Can Hydrogen Peroxide Be Used as a Teeth Whitening Agent?

Posted: 11/15/10 05:16 PM ET

Let's talk about Hydrogen Peroxide for a few minutes -- especially how it relates to your teeth and general dental care.

To start, Hydrogen Peroxide is a fairly common product, and has been used by people for years as a disinfectant/antiseptic, especially in the case of cuts and small wounds. Chemically, you might be surprised that Hydrogen Peroxide is fairly close to water. In fact, it's simply water with an extra oxygen molecule (water is H2O, Hydrogen Peroxide is H2O2). This doesn't mean you should drink it, of course, but it's interesting nonetheless.

An interesting fact about Hydrogen Peroxide is: is it universally sold in brown bottles. Why? Because light is the enemy of Hydrogen Peroxide, and continued exposure to light will slowly turn it into plain water. Thus, the brown bottles are used to keep light at bay. But even that won't help keep the product fresh indefinitely. Hydrogen Peroxide is fairly unstable, meaning it will degenerate no matter what. So keeping bottles around for years will definitely lessen the effectiveness of the product. You can increase the time you keep it by refrigerating it, but depending on how much fridge space you have, I'm not sure how practical that is (especially since it's so inexpensive).

As a NYC Cosmetic Dentist, I definitely use Hydrogen Peroxide in a variety of ways -- generally in the areas of teeth whitening. To start, Hydrogen Peroxide is a bleaching agent, and can absolutely help in whitening teeth. In fact, many over-the-counter tooth whitening products have a good amount of Hydrogen Peroxide -- sometimes as much as 10 percent (just to give you a point of reference, the brown bottles you buy are typically 3 percent.)

But this concentration comes with a price for some people -- there are certain side effects that will affect some (but not all) users. The main side effects are tooth sensitivity and/or gum irritation. These side effects seem to be more common in people who already have some degree of sensitivity, so if you find yourself returning from a dental cleaning with sensitive teeth, you may want to rethink using whitening strips or the like. But if you experience no side effects, then using Hydrogen Peroxide (in moderation) to help whiten teeth is probably OK.

Knowing that Hydrogen Peroxide degrades naturally is a very important point I am focusing on in this blog post. If it degrades naturally from light, heat and age then what's to say that the whitening strips, whitening gels and various over-the-counter whitening products we have to choose from are fresh? If the degeneration is a gradual process, wouldn't freshly made whitening gels/strips actually be more potent than those that have been shipped in a tractor trailer on a 100 degree sunny day, and then sat on a store shelf for 24 months? You bet they would. This brings me to my point: "stabilized Hydrogen Peroxide."

There are a few ways to stabilize Hydrogen Peroxide:

1. Preservative Compounds
2. Refrigeration
3. Complete Encapsulation

The problem with number one is that the preservatives prevent the Hydrogen Peroxide from "disassociating" which is something we actually want when we put it on the teeth. This may save the Hydrogen Peroxide from breaking down while it's on the shelf, but it also prevents it from breaking down when you want it to.

Refrigeration is a great method. If Hydrogen Peroxide is immediately refrigerated after being made, it can maintain its potency over quite a long period. And, once it's removed from refrigeration and used on the teeth, it will completely disassociate and provide a very effective bleaching of the tooth enamel. I have not seen this in an OTC product (yet), however we do use systems that utilize this refrigeration methodology clinically, and they are very effective.

Complete encapsulation is the most practical method. By encapsulating Hydrogen Peroxide in a vacuum sealed ampoule, you can prevent degradation as well. A good analogy here is soda. The carbonation in a soda can really wants to escape, but since it's in a sealed system (such as a can), it is unable to leak out. Many of the OTC systems use a very weakly sealed packaging system that is not immune to this degradation process like an ampoule is.

I hope this post gave you a little more insight into H2O2, and how it can be used in tooth whitening.

Until next time, keep smiling.

As a mobile teeth whitener in Arizona, with Sensational Smiles I have seen numerours clients with damage from in home remedies. No matter where you get your teeth whitened I recommend that you contact a professional. Take care of your teeth and keep them white the right way.

I've been using slightly dilute 3% peroxide as a mouth wash right after brushing for over 20 years and do have nice white teeth though not as white as those that are "done" but more natural looking. I also use Arm and Hammer soda and peroxide toothpaste the past few years but have noticed no change but like the idea of soda and peroxide in a toothpaste. I often brush my teeth with soda as my teeth feeling incredibly clean. I"m a growing older senior and since the seniors I know don't have white teeth I must assume my regimen has something to do with it.

H2O2 will result in increased release of mercury from your so called silver fillings.

Don't try to whiten "silver" fillings.

How come no discussion as to the potent free radical-generating effects of this reactive oxide? Will prolonged use result in increased incidence of oral cancers?

As a note, I do use H2O2 to brighten my smile. But I am also very aware of how reactive H2O2 is and how destructive it is to cells, cellular proteins and nucleic acids. That funny foaming action when used...yeah, that's your body defending itself, converting H2O2 into H2O and O2. Free radical generating compounds (just like ionizing radiation) is destructive and can/might lead to oral cancer. This is something we need to pay attention to.

A very interesting article written by a dentist. He specifically mentions that you shouldn't drink H2O2 and from that I can gather that he never has. While I respect his learned approach to H2O2 he omitted many salient points that need to be discussed when you tackle the subject of H2O2.

I have been on The Oxygen Therapy Program for the past 2 years. After 3 days every twinge of my arthritis was gone. After 3 months my doctor took me off of my high blood pressure medication and after 6 months I took my self off of Avandia for my diabetes.

Today, 2 years later, I am healthier than I have ever been and I owe it all to my oral oxygen therapy program.

All I can tell anyone who is interested is what it did for me and to do your own due diligence when looking for alternative therapies.

Everyone has their own agenda. This dentist is part of the established medical community and has been taught to revere pharmacological pills and potions to treat human ailments. I personally, own The Oxygen Therapy Program so there is my angle.

But my point is that everyone out here has an agenda and rather than become a pawn in someone else's plan, search for yourself and decide for yourself what works for you and what doesn't.

some doctors in alternative field use h2o2 to kill germs [ part of oxygen therapy including 4% ozone in nitrogen ]

15 years ago a toothpaste package ina organic health food store { Caper's in vancouver ] said it contains 2 enzymes which turn left over food particles in to hydrogen peroxide which kills germs it said in a healthy mouth [no dry mouth ] saliva contains these 2 enzymes

Hydrogen peroxide has been used as a disinfectant for cuts and scrapes on the skin for several decades, (probably at least 60 years) without being considered an "alternative" medicine.

I've always used it as a disinfectant and a mouthwash. I didn't realize I was being "alternative." I just thought I was cheap!
