Teeth Whitening Hydrogen Peroxide Hydrogen peroxide is a highly reactive chemical compound of hydrogen and oxygen. This chemical is widely used to bleach paper and textiles, and is used as a disinfectant in the medical field and in the household and is also the main ingredient used to whiten your teeth. Normal concentrations are about 3% and up to 10%. In general, the higher the peroxide, the greater the whitening power.
Adverse
Because hydrogen peroxide is a highly reactive chemical the two most common side effects are mouth and gum irritation over the increased tooth sensitivity to temperature changes, however, both effects are temporary. Hydrogen peroxide works so well because it can easily pass through the enamel of teeth and begin to interact with dentin and part of your tooth paste. Studies have shown that it does not harm or effect the party tooth enamel and is considered safe by the ADA.
Urea peroxide
Hydrogen peroxide and carbamide peroxide should not be confused because they are very different from each other. Hydrogen is a chemical that reacts much more quickly and has a very short lifespan. When mixed with oxygen and saliva, breaks hydrogen peroxide quickly led to short teeth whitening sessions. Urea peroxide was invented to slow down the decomposition process so that the peroxide last longer and provide greater effects of teeth whitening, and live longer.
What he does not touch
Hydrogen peroxide can not change the color of trim, porcelain teeth, ceramic teeth, gold teeth, or other restorative materials, because hydrogen can not penetrate the surface layers of these materials. However, it can do more work such as porous dental cements and dental amalgams, but the effect can be negative, making them softer or more soluble.
