Hydrogen Peroxide for dental care

I have been using hydrogen peroxide as a mouthwash after I brush and floss my teeth for the past 8 years. I just use the 3% solution that you can buy at any pharmacy. I take a swig of hydrogen peroxide straight from the bottle and keep it in my mouth for about 30-60 seconds before spitting it out. It bubbles up and sometimes tingles. If you are not used to it, it will feel weird but it won't hurt unless you have an exposed nerve. Make sure not to swallow it. I don't think that it will cause any huge problems but it will probably give you a stomach ache. This use of hydrogen peroxide is great because it not only kills bacteria and keeps by breath fresh but also makes my teeth sparkling white. One time my dentist commented on how white my teeth are and I told him about the hydrogen peroxide and he jokingly told me not to tell anyone about it or he would lose business.

I have been brushing my teeth with hydrogen peroxide and baking soda for years, especially since new information is out about the harmful effects of flouride.

For those who have been warning that hydrogen peroxide should not be taken orally, why is it that so many over-the-counter toothpastes now advertise hydrogen peroxide as a beneficial ingredient?

Keep up the good work EC!

I use Hydrogen Peroxide when flossing my teeth. Mix the HP 50:50 with warm water and close your mouth tightly while you are flossing. I used the reach flossing thing and it worked really good. Just try it. HP is as good if not better and cheaper than name brand mouth wash. It helps with gum disease.

Plaque removal: use 1/2 capful hydrogen peroxide in a little bit of water and swish around in your mouth after brushing.

I love this website. the thought of losing so many loved ones recently makes me very sad. had i known about earth clinic, perhaps they would still be here. i have been using several different remedies. i tried the hydrogen peroxide method first. i use it in my water mostly, but sometimes i use the spray pump. i smoke heavily and my breathing has changed so much for the better. i have much more energy and overall feel good. i am diabetic and have very dry peeling feet. i soak my feet in enough water to cover the top of my feet and add about 1/2 c. peroxide to the water and soak about 30 minutes or longer if i have the time. after 2 times, i could see my feet start to heal. also, i found 3% peroxide without stabalizers at the family dollar. i can taste the difference. thank you so much.

Stop smoking then! It's not magic, you have to put some effort into it. (says my hubby next to me, I concur). Cinnamon capsules are available everywhere now, even walmart. 1 gram (1 of the fat caps or two of the smaller). It anchors into the nicotine receptors and reduces craving. I saw this and used it on my first hubby that was a 2.5 pack a day smoker- he went to smoking 1 pack without knowing I had added something in his vitamins.

H2O2 safety :

It has to be food grade H2O2. The bottle I bought is 12%, this has to be diluted down to a maximum of 3% . I am starting with 6 drops of the 12%, 3 times daily in half a pint of water, this is way under 3%, 3% is for mouthwash and external use .. I hope no one ever puts 12% H2O2 in their ear undiluted.

Please, if you recommend hydrogen peroxide for any personal use, STATE THE % DILUTION !!

It is not good enough to simply say Hydrogen Peroxide, as this is available in a various concentrations up to as high as 30%.

Is using distilled water essential to the effectiveness of the treatment? I noticed my 3% hydrogen peroxide is mixed with distilled water but couldn't manage to find any so have been using de-ionised water instead but after 6 dips have seen no real improvement.

Am I rendering it pointless by using the de-ionised water?

I have 8% FGHP in 16oz bottles. What is the dilution to bring it to 3%?

Gingerg: Pour 8oz of your H2O2 into an empty 16oz bottle then add 8oz of filtered water to each half full bottles, and you will have 2-16oz bottles of 4% H2O2.

Always use 35% food grade hp which can be bought at a health food store, dilute with 8 oz. of distilled water. start with 3 drops of hp in 8oz. water three times daily. I had copd, emphyzema, and other lung problems, they are all gone my dr says he can't believe it.

I have been doing alot of research on Hydrogen Peroxide and from all that I am finding, when mixed with water it breaks down VERY quickly. Is this not so if it is mixed with distilled water? If not, how long will it last after mixed?

Your 29% Hydrogen Peroxide - 1 oz. To 10 oz. distilled water. Mix 1 oz HP to 10 oz distilled water. Good luck!

Can some tell me how to mix 29% hydrogen peroxide with distilled water so that I can drink it. I have COPD and hopes that it can help me!!! Thanks

I would like to share a reposting of a helpful H2O2 Dilution Table that someone submitted a while back. It works wonderfully!

Hi Bill, I would like to know as to how an elderly healthy person can make use of food grade H2O2 to improve general health. At this age though there may not be any symptoms but arteries will have some blockages, lungs capacity will be reduced and so on. Is it ok if one takes three drops of 3% H2O2 in some green juice a day or you feel to follow any particular method, please give your opinion. It will be of great value. Thanks, Baldev

Hi Baldev...Nice to see you back on EC.

Many serious Hydrogen Peroxide users advise slowly working up to 25 drops FG Hydrogen Peroxide 3 times a day for serious problems. But this type of supplementation can be harsh on the body and will likely cause problems like nausea, headaches etc. If that happens using high dose HP then just taking one gram dosages of Vitamin C to neutralize the excess HP should resolve these side-effects fairly quickly.

But, like you, I personally think a gentler approach with HP is also beneficial. A dosage such as just 3 drops a day in water, as you suggest, would certainly be beneficial over the long term. In fact Ted from Bangkok relates a story on EC of how he improved his liver condition by taking low daily dosages of 0.5% HP over the longer term for over a year. And by taking HP in this way -- at a much lower daily drop dose -- would also mean that there would likely be no side-effects at all as compared with the higher drop dosages.

For more info on Hydrogen peroxide usage, there are some good alternative books out there such as The One Minute Cure and Hydrogen Peroxide: Medical Miracle.

I would also agree with you that hydrogen peroxide therapy would be useful for older people because it supplies oxygen to the body and, in this way, helps to revive cells and organs and would give you more energy whilst also boosting the immune system by killing a wide range of different pathogen species just on its own and, in this respect, it is also particularly good for the heart.

There are several alternative and proven solutions for calcium build up in the arteries. Linus Pauling's Vitamin C/Lysine therapy is one. Using a combination of niacin and lugols iodine or SSKI supplementation is another -- this was used in the older pre-WW II medicine and was called iodio-niacin(50 mgs niacin, 120 mgs potassium iodide per pill) which was fairly successful with few, if any, side-effects as compared to its more dangerous modern equivalent -- statins. I'm sure that you know about these alternative remedies for arteriosclerosis too. Another one that Ted mentions as a good calcium chelator is Trisodium EDTA -- but this is not so easy to get. And if you have to deal with thrombosis type blockages caused by fibrin build-up then using protease enzymes like nattokinase or even bromelain and papain are also useful.

For me, as a simple preventative, just simply taking the chanca piedra(bhumyamalaki) herb as a tea or decoction with magnesium supplements would also have great benefit against arteriosclerosis, high blood etc. The magnesium would help to more strictly regulate the calcium to proper levels in the cells and blood while the CP acts to reduce the calcium. And, just for an encore, CP also reduces blood lipids, lowers blood pressure, lowers cholesterol, lowers blood sugar and has anti-viral action as well. The chanca piedra herb also has no known overdose/toxicity effects on the human body but might have contraindications with some similar-acting modern drugs.
