Rinsing with Hydrogen Peroxide for Teeth Whitening and Healthy Mouth

A Hydrogen Peroxide Solution Bottle, Pearly White Teeth and Apples

Homemade hydrogen peroxide mouthwash?

Want to naturally whiten your teeth? I was hanging out with a friend over the weekend and he started telling me — almost out of the blue — about how awesome hydrogen peroxide was for your mouth and teeth, giving him a pearly bright smile. Oh yes! I remember how the conversation started. I was telling him how I spent $500 last month at the dentist to fill 2 cavities.

He’s been using hydrogen peroxide for a while now, rinsing with it about 2 times per day to strengthen and whiten his teeth, as an alternative to expensive teeth whitening procedures. He said that the peroxide actually fortifies cavities (essentially, repairing them) and hardens the enamel on your teeth to prevent cavities from forming.

It’s funny, because a few months ago, I heard a few actors in a movie talking about how hydrogen peroxide is good to gargle with to help fight mouth infections and sore throats.

So, after my friend’s advice and remembering the movie… I decided to look further into the hydrogen peroxide issue today. And from what I found, it’s true.

Hydrogen Peroxide Uses (H2O2)

Hydrogen peroxide (3% hydrogen peroxide) helps with the following:

  • Strengthens teeth
  • Fight mouth bacteria
  • Heal canker sores
  • Soak and wash vegetables/fruits in to kill bacteria and neutralize chemicals
  • Brush teeth with for extra protection
  • Soak toothbrush in for a few seconds to disinfect (daily)

Of course, don’t be surprised if your dentist tells you this is bullshit . Why? Because they don’t want you taking care of your own teeth with “your own” natural remedies. They want you to have cavities and they want your teeth to be black as dirt. Why? Because that makes them more money.

Here’s what you do to whiten teeth naturally with hydrogen peroxide

  1. Clean your toothbrush with hydrogen peroxide to disinfect it
  2. Rinse 30 seconds to 1 minute with 3% hydrogen peroxide
  3. Brush your teeth in up and down motion

You’ll have to experiment with the hydrogen peroxide usage. Some people use it a few times a week, some people use it 2 times a day. Some people rinse for 30 seconds and others hold it in their mouth for 10 minutes. I’m going to start off with aforementioned guidelines once a day and see how it goes. Cheers to that new bright smile! Here’s a teeth whitening kit you may like.

Here’s some additional information and techniques on natural teeth whitening.

Other Uses of Hydrogen Peroxide

Hydrogen Peroxide is commonly found in households where people use it for little things like disinfecting small wounds etc. You may find it at your local drug store where it is sold for home use in a diluted form containing between 3-10 percent of Hydrogen Peroxide. The other uses of Hydrogen Peroxide include an antiseptic gargle, bleach for clothes and removing wax from the ears.

Update: 7/5/2009 – I recently read that hydrogen peroxide can weaken the filling in your cavities. I suggest looking into the usage more before using with cavity fillings. Also, please never use a higher concentration solution of Hydrogen Peroxide for any kind of oral use as it can be dangerous at that strength (less than 10% is okay).

    I wouldn’t use hydrogen peroxide as a regular part of an oral care routine. It can negatively effect the skin of your mouth:


    Gum disease and cavities are caused by a contagious bacterial infection. Repeated daily exposures to xylitol will kill this bacteria. Listerine twice a day is also good as is a rinse called Closys (you can get it at Walgreens). Closys can also whiten your teeth if you use it regularly.

      • Fereda says

        Fluoride is actually a really really good thing for your teeth im a dental assistant student i know. fluoride is a mineral that will strengthen your teeth which is why it is in toothpaste and many other oral products and when u go to the dentist they will almost always give u a fluoride solution to put in your mouth it is ur best friend when it comes to keeping your teeth healthy.

          • Mikhail says

            Fluoride is actually used by the teeth, and there is not really enough of it in toothpaste to cause serious problems unless you eat (yes, eat) two+ tubes a day. I’d suggest carefully reading the things you intend to use to attack western medicine.

            Of course, if you’re stupid enough to swallow mass quantities of fluoride (as opposed to using it to clean your teeth with and then spit out), then you deserve fluoride poisoning.

            Hydrogen peroxide can be used to whiten teeth, but it doesn’t really do much for bacterial infections on its own.

            • Scott says

              You seem to forget the ability of the gum’s to absorb fluoride. Even if your not swallowing it you still will be giving your self more then you every would want. I suggest non-fluoride toothpaste. Besides even if you never get fluoride poisoning it is still harmful to the body. Many human and animal studies will support that. It’s believed to be harmful to the brain and can actually cause fluorosis. It’s a wonder anyone uses it.

            • Manny says

              my head almost exploded when i read that initial comment.. so i Just wanted to add this to your argument. “Fluoride is
              considered by the U.S. Centers for Disease Control and Prevention as “one of 10 great public health achievements of the 20th century”

              if u fill a glass with fluoride and drink it your are an absolute moron. Hydrogen(the most natural element in the universe – and 2/3 of the chemical makeup of pure water) is also poisonous to the human body if you are idiotic enough to drink it in its pure undiluted state.

        • In Seattle says

          Fereda, How sure are you that fluoride is an element? I think you’ll find it isn’t. To all others, dilute the hydrogen peroxide with water. Using undiluted will dessicate your gums.

          • Jess says

            I think what you all are referring to is SYSTEMIC flouride. Yes, SYSTEMICALLY (as in throughout the body, or ingested) flouride can be harmful. However the method for which it is used dentally is topical. Topical applications such as mouthrinses or foams at your dentist office have not been known to cause poisoning UNLESS INGESTED. Topically on the teeth strengthens enamel and can actually repair some incipient cavity lesions. It is especially important in children as their teeth are still developing and TOPICAL applications can help strong healthy teeth come in.

            • barlesinger says

              The American Dental Association has *NEVER* come out in favor of the use of fluoride on teeth, in rinses, in water or in little pills. All these 0practices, and especially water fluoridation have always been very contentious ideas to the ADA.


              SODIUM FLUORIDE is a rat poison and it is also damaging to the body as a whole. It is the fluoride used all over the world. It is also the wrong one. Calcium fluoride is the one that strengthens bones and teeth and it is used by natural medicine docs for the purpose (because they take biochemistry and listen in class).

              That said SODIUM FLUORIDE is actually PRESCRIBED as a treatment in little pills by dentists and docs all over the USA to harden kids teeth in areas that have soft water (or where rain water is common for drinking). This has killed a whole lot of little kids, by giving them bone cancer. Look it up.

              SODIUM FLUORIDE is also added (for no good reason) to WATER SUPPLIES in the USA and it causes a whole lot of health problems. IN fact hundreds of wells put in by UNICEF in India had to be capped forever, due to high levels of fluoride, which have the kids cancer and twisted leg bones. Contractors were paid by the meter, and bypassed safe water for water further down. It was a well documented international scandle.


              AGAIN there are two major fluoride salts, and the one used by dentists and added to water supplies is the WRONG ONE – sodium fluoride. The stuff commonly used for (supposed) tooth health is actually a toxic waste and a rat poison and has similar effects on the brain to lithium. Sodium fluoride, which comes from the the aluminum and uranium mining industry. Look it up on google. They sell it off to water districts, put it into mouth wash and toothpaste and also little white pills to EAT. They do this in order not to have to dispose of it (very expensive)…except…that sodium fluoride is also used as RAT POISON.

              The habit of selling off toxic waste as a “value added” instead of properly disposing of it; is very common: Heavy metal waste is so,d exactly the same stuff, as fertilizer for farmer fields (and it poisons their fields). Artificial vanilla (vanillin) is made from the dioxin rich waste of the paper and pulp industry.

              Now it is true that fluoride, used in very small TOPICAL quantities, with a PROFESSIONAL application where the gums are first coated to protect them body, does have an enamel hardening effect… from topical fluoride. However sodium fluoride is still very poisonous no matter who uses it or how and it does not leave the body easily. It builds up in the body over time and does damage.

        • Gordon says

          :) …….. that’s the expected response from those educated in the industry. My sister is a Hygenist and says the same thing. It is obvious that the natural remedies are not taught so they are refuted. When it comes to ‘fluoride’ ……. I run the opposite direction ….. don’t ever believe what you are told about it … period.

        • Joshua says

          Fluoride is a poison, that’s why toothpaste labels warn not to ingest it. Too much fluoride can have dramatic results. I wouldn’t be surprised if dentists use fluoride to make your teeth weaker just to get more money out of you. I don’t trust so called medics or dentists. Their all out there to make a buck. Sure they don’t want you using home remedies, because they would be out of jobs. All the dentists on here knock using any form of home remedies. They make sure to tell you to check with your dentist or to only whiten your teeth by a professional. I’ve brushed my teeth twice a day all my life, yet still have had more cavities then i should of ever had. Just makes you wonder, how do you still get bad teeth when you practice so called good “oral hygiene”. It’s all a fraud, a scam, a business. Their in it together.

        • Darren says

          Flouride is in rat poison.
          It is in your water, toothpast and anti depressants. absorbed threw taking showers (your skin) and drinking water. Just read the poisen label on your toothpast.
          How can this be intake regulated? a two year old vs a 40 year old.
          Now why does Europe who bands this in 95% of the drinking water have less cavities than our kids…..Hello

    • NathanPyndleton67 says

      Hydrogen peroxide is PERFECTLY SAFE to use orally! I have used it and it works great! Here’s how:
      1. Brush teeth as usual
      2. Rinse with water
      3. Put .5 – 1 oz peroxide in your mouth and GENTLY swish for 1 minute, allowing it to sit on your gumline
      4. Spit out peroxide
      5. Rinse mouth thoroughly with water.

      You have just killed bacteria and strengthened your teeth. Now, stay away from junk food and you wil never have to worry about cavities or gum disease again!

      Dentists use peroxide to whiten your teeth, too. Now you can do it yourself for 85 cents!

      • Sarah says

        I agree with Nathan. I used to have gingivitis and NYU Dentistry recommended I use perioxide as a rinse to reduce bleeding and swelling. I did that for several months and I never had gingivitis again!!! It also made my teeth very white.

      • Janis Owens says

        I have used peroxide as a mouth rinse for some time since other “mouth products” took off the lining in my mouth (including Colgate toothpaste.) This didn’t seem safe to me so I went (back) to peroxide. However it took off the lining in my mouth as well although I had used it in the past with no problems. It recommended diluting it half and half so that is what I now do and have had no further problems. I also gargle with it as a preventative measure-and of course use it on wounds and such.

    • gary says

      I have used peroxide for about 6 years.dosen’t whiten my teeth but kills a lot of germs, (good and bad).So I wouldn’t over do it. I use it once a day reduce with one part mint mouth wash and nine parts peroxide. Don’t have that funny taste.

    • Sarah says

      It is very safe. It worked for me. I don’t suggest you keep it in your mouth for too much for too long each time you use it, your gums and tongue feel like its burning. A small capful is sufficient. See my comment above, under Nathan’s.

  2. D says

    Too many articles about the same bull crap. What about the baking soda with peroxide, etc? How about providing some evidence on your own teeth and showing some progress before blowing the trumpets??

    How do I know about peroxide because I tried it, and wrecks your gum.

    Too many eat arse posting the same bull crap….oh, and I’m no dentist either…you just make the world worse than it already is with your lies.

    • david says

      to the i’m no dentist perhaps you should have washed your mouth with a bit stronger solution of Hydrogen Peroxide then maybe the rubbish and filth coming from it would not be there. I use Hydrogen Peroxide on my teeth and have had no problems.

      • D says

        ?? Well that makes sense….your no dentist but an expert in rubbish and filth who recommends anything higher than Hydrogen peroxide (3% hydrogen peroxide)?? Maybe you can show us your teeth from stein and to whitening. Please don’t tell us how its done but show some evidence day by day.

        If I hear another expert with no real evidence or footage……UM….SHUT YOUR MOUTH!!

    • dan plesse says

      The Hydrogen Peroxide study experiment which I passed onto David in2009 was only a single
      experiment out of hundreds and since that time I have stopped using hydrogen altogether. I started using antibacterial agents to fight tooth decay and got better but not complete protection. I am currently testing a green gunpowder tea direct eating of leaves not drinking as a weight loss program and I am on day 5 with that. The idea combines garlic too and lots of water and outdoor running and biking. I will bike until sundown and try to reduce eating via 1. too much at each sitting 2. fewer meals and so far so good. Remember correlation does not imply causation so be careful and be well. By Dan Plesse. experimenter.

    • mary says

      Silly comment.. Hydrogen peroxide has been used for years and years to whiten teeth.And as a mouth wash..Because years ago there were no mouthwashes and toothpastes like they have today..
      It is perfectly safe and will whiten teeth.. It will not harm your gums .It actually helps get rid of harmful bacteria..
      You shouldn’t swallow it.. Of course ~! Why would you want to?
      Rinsing your mouth out with water afterwards gets rid of the taste..
      If your not into buying a $1.00 bottle and would like to spend $50. Or more to whiten your teeth elsewhere..Fine..
      But I sure don’t….
      And I sure trust hydrogen peroxide more than I do harsher bleaching chemicals ..

      • dan plesse says

        Thanks Mary,

        After my last comment I actually returned to Hydrogen peroxide but only at 3% and in combination
        with tooth paste. The green gunpowder tea experiment was a no go.


      • jessica says

        mary, i agree we shouldn’t swallow hydrogen peroxide. however, if your dog should swallow something dangerous like a pill not meant for them, you can make them swallow 1 tablespoon of it and in a few minutes the pill will come up in a foamy mess caused by the peroxide! the dog wont be happy but WILL live!

        I have used hydrogen peroxide for years to whiten my teeth and am very happy with the results!

    • fay says

      Wow, D! Is the world ending for you or what?…To all -If you eat alot of crap then it fallows that it won’t whiten your teeth, it does sting a little when you rinse because it is killing bacteria. If it is hurting your gums after use dilute it or use something else but most anything else you use will have some side effect too. Your best bet is to eat fruits and vegetables and sparingly breads and grains. If not, deal with the consequences.

  3. Cob says

    You dont know anything about h2o2 dont you? It releases free radicals which are very active, and they can cause a lot of stuff in your mouth. Including cancer. By the way, desinfencting your mouth too much is also bad. I`m pretty sure you havent heard about dysbacteriosis.. Good luck with hurting yourselves.

    • jerry t says


      Ever put hydrogen peroxide on a cut? It will bubble as it disinfects the wound. I was told by my dentist that I should have my teeth whitened at his office for about $500. I said I read that dp works just a well. He answered that it did but it took much longer. Let’s see $500 vs. a few bottles of hp at $1….the winner is Hydrogen Peroxide by a long shot. Now I use it daily and have whitened my teeth several levels.

      • crystal says

        My moms dr told her using peroxide on a cut is a sure way to end up with a scar because it will eat at living tissue, not just disinfect

    • ron says

      Wrong again. Hydrogen Peroxide hyper-oxygenates by virtue of its chemical make-up. They use it in homeopathic medicine cancer hospitals like Hospital Santa Monica. Reason being is that cancer cells don’t like oxygen and don’t survive well in a oxygenated environment. You sound quite hypocondriacle. Your preocupation with and or reference to dysbacteriosis is a CLEAR sign of that. You’re not going to hurt yourself with h2o2 as a mouth wash when used with some common sence. You’ll find that unless you have some kind of sensetivity to it (Just dilute it 50/50 with water), its actually helpful. Talk all the smack you want but ” Dems da Factts” ! LOL Have Fun………..

  4. Bill says

    I’m gonna try it. My dentist told me once to use it when my filling was infected. It worked well for that and as long as I rinse real well I’m convinced my mouth will soon fill up with lots more bacteria so fearing dysbacteriosis just seems silly. But hey, I’m not a doctor I just play one in my mind…

    • dan says

      Its working better mixing it with toothpaste I think. I remember aspartame having a warning label and now that warning label is gone and its in all the candy. Checkout Wendell Potter: Health-Care Exec Turns Whistle-Blower and Mike Harari on 9/11.

  5. Christina Thompson says

    Has anyone used peroxide that has fillings? I would like to try it but I have a few fillings, and I don’t want to weaken them. I’m just wondering how it has worked out for others with fillings. Thanks!

    • Janis Owens says

      Yup, got a major mouthfull! About every 20 years or so I might lose the one in my front tooth but otherwise I don’t recall losing any. Ya, I’m an “old horse”…

    • Rick says

      Check the web. Peroxide will significantly increase the release of mercury in your amalgam fillings. It wont happen overnight but if you use this stuff on a regular basis, the mercury will accumulate in your system and can cause a number of health problems.
      Be careful with this stuff if you have dental amalgams.

  6. jenny says

    i started using it and it has worked great for me. i have never been to a dentist (i am 16), but i had problems with my gums. (skin would just come off them and i could wipe it off with my finger) but after seeing this website and using peroxide i have had no more problems and my theeth are whiter! its pretty awesome!

    • Jim says

      I think if your 16 you didnt have a problem in the first place. Dont know to many 16 years old with less then white teeth to begin with.

      • Grant says

        hay i have braces and drink a lot of soda and have green theeth and im 16 where u live africa jim iv use proxide four a whole 3 years a whole wapping 3 years and it took away my infections and now i lowering my gum line which i need and also i had a whitening problem and my dentist said to lower you gum line and help lower yo gum line swish 3% hp and this will in the long run fix you problem (this was when im 14) and it did only reason my theeth are no so good no is because iv stoped useing it because im out of it only reason people dont like useing this product is because it kills good and bad cell… dont go kissing every one and skip brusing you theeth and rinsing and you will do just fine.

  7. rosie sparks says

    so i used hydrogen peroxide to whiten my teeth. it did work but my gums also got damaged. did this happen to anyone else or just me?? and should i see a dentist about my gums??

    • Sarah says

      Did you leave the peroxide in your mouth for a long time? And how long ago did you stop using it? I had gingivitis as a teen as well. I used a small capful each time I brushed, 3 time a day. Held it in my mouth for a couple of minutes, then rinsed with water. I noticed that when I used too much perioxide and kept it in for too long, my gums would get white and look discolored but all that healed in time. I did this for several months until my gums healed (25 years ago) and I haven’t suffered from gingivitis again.

    • mary patchell says

      all of a sudden my teeth and gums hurt. i can only figure it is from my use of baking soda for all my brushings and hydrogen peroxide almost every day. i’m rinsing my mouth with salt water to relieve the pain.

  8. Jackie says

    I used Hydrogen Peroxide while undergoing chemo to help prevent and heal sores in my mouth. My oncologist and dentist both suggested that I do this once or twice a day. It worked to heal my mouth and I have continued using it after I brush at night. There are some theories floating around that dental bacteria causes cancer, so I have adopted this ritual as a preventive measure.

  9. says

    My dentist (>30 yrs experience) recommends to this day peroxide for keeping gums healthy.

    Only disadvantage is it seriously leaves your mouth tasting like crap, however a light brushing or clean water rinse is enough to take care of that problem.

    • Jessica says

      I have seriously swollen gums due to medication. Does anyone have any experience using peroxide to prevent this and infection while taking Dilantin (Phenytoin)? I cannot afford the dental treatments that I would need to cure this. I have been to a gum specialist just for a consultation and there is no way I can afford those treatments. .

      • Jess says

        Unfortunately overgrown gums can be a side effect of Dilantin. As a dental hygienist I have seen this many times. HP can be used for infections in the mouth but will not cure the swollen gums. However caution should be used when using HP as well. While it is good for infection, don’t rinse too long. Maybe 20-30 seconds and only a small capful. Using it too often can also cause Black Hairy tongue where the papilla on your tongue become overgrown and turn brown/black.

    • Verve says

      I just bought some 3% H202 from our local hairdressing supplies shop, to whiten and disinfect the mouth. They also have 6%, 10%, containers, etc, right up to 18%, after which it is too strong for the hairdressing industry. My question is: If I buy 6% H202 and dilute it 100%, will this bring the concentration down to 3%. The lass in the shop suggested that the suppliers say this is not an accurate way of bringing the concentration from 6% down to 3%. Could anyone clarify this please.

  10. Brandy Watford says

    Test the power of HP! Place a washcloth in a sink… close the drain …add water and 2 oz. of HP …see what happens.. Clue…. something that your soap didn’t do! Try it.

  11. JJJ says

    i’ve been using peroxide as a mouthwash once a night for about a minute, for 4 months now and have had no problems whatsoever. no canker sores either which is why i started using it in the first place. my teeth are also definitely whiter.

  12. Raw raj says

    I started to search for hydrogen peroxide after I found 2 “approved” tooth whitening products that uses H2O2 as a whitening agent.
    A 7 day pack that includes some “unique” application popper costs around 100$
    Apart from Alcohol and some thickening and “spreading” agents(which are dangerous for health BTW) all it had was H2O2
    So I decided to check if people were using food grade H2O2.
    So to all those who are saying it does not work(either they used too much or their gums are already damaged from the chemicals that exists in todays general dental products and ofcourse their diet) are TROLLS for sure.(or dentists or maybe paid “commenters” yes they exist there are agencies who give such services around a year ago GMO companies were found guilty of using such services to “argue” on websites that were exposes the dangers of GMO food and to spread lies about its benefits in regards to “yield”.)

    H2O2 can be damages to already damaged gums. What I wanted to share here was how these 100$ products(and another that was around 12$) work.
    They have method like a brush(or more advance “pop and cap” B.S.) that applies the H2O2 only to the teeth.
    So maybe if people are having problem with gums then they can apply the product with a brush also mix it with some glycerine to thicken (as these products use glycerine too) and only apply to the teeth and keep for a longer time.
    You can rinse your mouth for just 30 seconds to avoid any issues with gums after that. Rinsing for 30 seconds should be safe for anyone.(and yeah sort out your diet eating a whole food plant based diet would do wonders not only for your “inflamed” gums, as a plant based diet is highly anti-inflammatory)
    Thank you for this article and thanks to those who took time to post the comments and their experiences, I can save 99$(or atleast 11$) and buy the 1$ bottle of H2O2 and whiten by teeth at home.

    • orange says

      Thanks for the glycerine idea! Exactly what I was looking for. I wanted to make a peroxide paste that I could smear on my teeth – something that would stay in place. A mixture of peroxide and baking soda does not work, as it slides off the teeth. I will be experimenting with the glycerine.

  13. Bryan says

    does it help with Streph throat? Im on antibiotics for strep throat now, Ive been using it too., figured it couldn’t hurt gargling with the stuff

  14. Breanna says

    Hi! I’ve read through all the comments and I’m just wondering because my boyfriend told me that doing this kills your teeth, is that true?

    • Ella says

      To “kill” a tooth (as you say), you’d really need to damage the nerve. If HP got to your tooth nerve, you had more problems than needing whiter teeth.

  15. Thomas says

    It’s not fair to call hydrogen peroxide ‘natural’, produced by the electrolysis of sulfuric acid and ammonium bisulfate. Hydrogen peroxide decomposes in nature to oxygen gas and water.

    Hydrogen peroxide do have important and good uses, as a bleaching agent and as an antiseptic. But ethanol, chlorhexidine and sodium hypochlorite is recommended over hydrogen peroxide – but do not make your teeth whiter.

  16. Whitey says

    Please be careful – my mouth was still kind of nasty after a sinus infection so I used 3% to rinse my mouth out TWO WEEKS AGO. My toungue is still white, like WHITE, feels constantly like I just ate salt – and it is a tad cotton-mouthy as well.

    It looks so creepy… I only rinsed for about a minute. Be careful folks, I would dilute this stuff. Ugh.

  17. Janelle Davis says

    So I just tried rinsing with hydrogen peroxide and wasn’t bad. If by the time I wake up in the morning and there’s no problem, I’m going to start using it daily. It didn’t taste bad, either…really it had no taste.I’m 21 and I’ve been a smoker for a few years and my teeth turned yellow and so I’m trying to find something that will help whiten my teeth. I hope this works.

  18. says

    I’ve been rinsing with P for weeks now and find that I can see the difference. I also cannot use toothpaste as I have a salisolate sensativity (plant based products) so I use baking soda instead. Not sure if the combo of these two is making my teeth whiter or not but pleased with the results for sure.

    I see comments escalating over who’s right and who’s wrong…really? We are all different and being so, know that one solution works for me and may not for you. Try it and if you’re not happy with the outcome, stop doing it and try something else. Say that you did and don’t badmouth others because it failed for you. Most of us left the 3rd grade years ago and are chosing our battles.

    • Sean says

      Well said, Tammerjack! After reading everything down to your comment, YOURS impressed me the most and is SO TRUE!! I couldn’t have made this point any better!

    • SkepticRina says

      I love Hydrogen Peroxide. My mouth and teeth feel so much cleaner and healthier and yes, whiter. I add peppermint or cinnamon extract in 3% HP and it tastes so much better when rinsing for a minute. Try it. It totally works.

    • Ben says

      This is a safe and effective method for whitening the teeth. All other comments saying this is dangerous should be disregarded as I have done this for years with no problems. Just mix 1 part peroxide with 1 part water and rinse for 1 minute or more. Also, try to avoid swallowing it.

  19. Marc says

    At the end of the day….the most important thing to remember about fluoride is that it is a waste product, produced by various different industries. you are essentially cleaning your teeth with crap.
    no it wont kill you if you rub it over your gums, but still…should you really clean your teeth with a waste product?

  20. Dan says

    Belive it or not, cocoa powder can rebuild enamel. It contains a unidentified white crystaline substance that rehardens teeth. Also try ashes of the grapevine. The microscopic charcoal polishes and removes stains.

  21. Clareee says

    I am 16 and I have been using Peroxide for about a week, twice a day. My only intention is to whiten. I use a q-tip and dip it into Hydrogen peroxide and rub it all over my front teeth, til they are foamy. It works great for me. It barely touches my gums and you can’t taste it after rinsing.

    H202 is safe, but I would suggest using trays to not overexpose the tissue.

    Peroxide is unstable and reverts to water and oxygen. Oxygen is very much like Flourine, a halogen. They aggressively bond with most other elements (needs 2+ to become balanced charge). This is why both elements react with calcium the way they do. Also means they destroy cells in the same reactive manner.

    Your own microbes are there for a reason, and the colony could die if too many are killed off with peroxide. That means any other “invading” microbe or bacteria can move on in.

    I have used H2O2 for over 30 years. Never had a cavity in my life. My teeth are awesome. Flouride is poison period. There is nothing wrong with H2O2 at all. Anyone who says otherwise is just trying to make $$$.

    I’ve been doing oil pulling to fix my gum problems and remove the plaques on my teeth. I take a spoonful of olive oil and swish it in my mouth. It works by trapping the bacteria in the oil. Kinda like cleaning the car engine with oil. I spit it out after 15 minutes. It is a cheap method and my gums look pinker now.

    DO NOT USE H2O2 AS AN ORAL RINSE IF YOU HAVE MERCURY DENTAL AMALGAMS. I had used 3% drug store H2O2 as an oral rinse for over a year.
    Took me a long time to associate the onset of a number of health problems with mercury toxicity from the use of H2O2. It’s been a month since I’ve stopped using H2O2 as a mouth wash. Symptoms are very slowly reversing. Be careful with this stuff if you have dental amalgams.

    I’m in my 60s with excellent teeth. I brush at least once a day, floss every other day, and rise out with hydrogen peroxide occasionally. Please note that you do not have to use HP every day. Eat well, practice good hygiene, and your teeth will last long a good long while.

    Keep smiling! :)

    I do not think other ways than the peroxide would be the best way to whiten your teeth. I have been using peroxide while I has a surgery from my back teeth. Doctors also suggest. But you have to be careful and should not use without a control of a professional doctor. Yesterday I was going around the internet and I saw a website called http://www.peroxideforwhiteteeth.com/ you can even find some reviews about peroxide out there. So I suggest you to find best one available in your country

    What is a lethal dose of Fluoride? 5 grams.
    It is recommended to drink 2 liters of water a day according to the FDA.
    But how much fluoride is in the city water? Minimum is 0.7 ppm or 0.7 mg/L
    NOTE: If you don’t flush heavy metals out of your body frequently then they stay.
    How long does it take to reach a deadly dose, if you were drinking city water at 2 liters per day? Daily intake 1.4 mg for every 2 liters. 5 grams divided by 1.4 milligrams is about 3,572 days! or 4 years, 6 months, and about 24 days. And if that isn’t bad Skeletal Fluorosis is just around the corner.
