Hydrogen peroxide teeth whitening

Hydrogen peroxide teeth whiteningTeeth whitening is more important than ever. An attractive and confident smile is no longer considered a celebrities’ advantage. Now, we can all have the bright, white teeth of our dreams, and home-whitening products seem to be available everywhere. A healthy-looking mouth and a radiant smile can bring us closer to personal or professional success.

Bleaching is the most commonly used method of teeth whitening and the most effective so far. However, various substances are used for bleaching and there may be several differences between them. Most home teeth-whitening kits include a whitening gel which contains either hydrogen peroxide or carbamide peroxide as their bleaching substance.

What is hydrogen peroxide?

As its name suggests, hydrogen peroxide is a combination of hydrogen and oxygen (H2O2) and it has a liquid, water-like form. In nature it is formed with the help of the sun and as a by product of several organisms.  It has a strong oxidizing capacity and it is medically used to treat cuts, wounds or injuries. Moreover, in high concentrations it is so powerful that it can be used even as a rocket propellant.

At home it is used as a cleaning agent in different washing powders for clothes or general cleaning and in cosmetics for skin care or personal hygiene. Also, hydrogen peroxide has strong bleaching capacities and that is why it is the active ingredient in carbamide peroxide.

What is the difference between hydrogen peroxide and carbamide peroxide?

Several whitening kits contain hydrogen peroxide while others use carbamide peroxide. It seems that carbamide peroxide is more effective, because when it comes in contact with the saliva in the mouth, it releases hydrogen peroxide in a natural way.

This process may be slower but it bleaches the teeth more naturally while the molecules produced, which are called free radicals, are steadily produced for a longer time. In this way, bleaching takes place smoothly and effortlessly, and this means less drastic impact on the teeth and much safer results.

Dentists usually show a preference to carbamide peroxide mainly for the long-lasting results it can have. Hydrogen peroxide also offers good results but its whitening effects wear off fast. Another reason is the long shelf life of carbamide that saves dentists from frequent orders, and finally, because it is a more stable substance than hydrogen peroxide.

A serious danger of home teeth-whitening kits is the tendency of some people to continuously improve their already good results and the temptation to use the treatment again and again. Teeth whitening is absolutely safe if used according to the recommended frequency, but it can damage tooth enamel if it is overused.

The only way to enjoy beautiful, bright teeth and an attractive smile without running the risk of causing permanent damage to your teeth is to follow the instructions that come with your package, and never exceed the recommended treatment time because you think you are going to have better results.
