Hydrogen Peroxide Teeth Whitening

Can Hydrogen Peroxide Whiten Teeth

The majority of teeth whitening kits use a gel called Carbamide Peroxide, this is available in many strengths ranging from 10% right through to 35%. Generally speaking, the stronger the gel, the quicker it will whiten your teeth, however BEWARE…..  Gels that are over 22% are more than likely to cause adverse side effects that include teeth and gum sensitivity.

The FDA in America only approve Carbamide Peroxide gels up to and including 16% strength.

Some Dental Surgeries and a few teeth whitening kits are now using Hydrogen Peroxide gel in their kits.hydrogen peroxide teeth whitening

What Is Hydrogen Peroxide

Hydrogen Peroxide is a reactive chemical consisting of hydrogen and oxygen, more commonly used to bleach textiles and paper and is commonly used as a medical disinfectant both in the home and in hospitals.

When used in teeth whitening kits, strengths can range from 3% up to around 6%, generally the stronger the concentration of peroxide, the better the whitening potential.

Does Hydrogen Peroxide Cause Any Side Effects

Hydrogen peroxide is highly reactive, and when it mixes with oxygen and saliva in the mouth it can whiten teeth quite quickly. It works well because it can pass into the enamel quickly, and some manufactures claim that hydrogen peroxide is 4 times faster than standard whitening gels.

The problem is however, that it can cause adverse reactions similar to those caused by over strength Carbamide Peroxide gels, other issues can be increased teeth sensitivity to changes in heat and cold..

Differences Between Hydrogen and Carbamide Peroxide

Hydrogen peroxide is a volatile compound and can be effected by high or low temperatures. That is why there are not many home kits that use it, in professional dental surgeries, the temperature can be kept at correct levels, but the makers have no control over where and how everyday users would use and store kits with hydrogen peroxide gels.

Carbamide Peroxide gels will last longer and tend to have an effective life span of around 2 years.

As a strength comparison, 6% hydrogen Peroxide is comparable with 16% Carbamide Peroxide.

What Is Best – Hydrogen Or Carbamide Peroxide Gel

Different manufacturers will argue the case for the two, Hydrogen peroxide is without a doubt faster at whitening teeth, but its instability and the chances of adverse side effects from it use are possibly higher.

The suggested short shelf life should always be taken into consideration. Carbamide Peroxide is a bit slower at whitening teeth, but shouldn’t cause too much in the way of side effects as long as users avoid gels over 22% concentration. Its longer life expectancy could offer better value for money in the long term.

Neither Hydrogen Or Peroxide gels will whiten fillings, crowns, veneers or any other restorative dental work, there has also been some reports that hydrogen peroxide has in a few cases affected dental cements and amalgam fillings by softening them.
