This causes oxidation of organic pigments that are mainly located within dentine, which results in a reduction or elimination of the discoloration.

Composed of 6.5% urea and 3.5% peroxide, 10% CP is active up to 10 hours in the mouth, while hydrogen peroxide is only active for 30 to 60 minutes. It further removes plaque, kills bacteria and elevates the mouth's pH which results in fewer caries and acts as a tissue healing agent.

The legal limit for a dentist to use is between 0.1% and 6% hydrogen peroxide. These higher percentage products used by a dental professional will produce a safe, effective and long-lasting tooth lightening result.

Choose the right concentration: A low concentration of Hydrogen Peroxide (around 3% to 6%) is safe to use for teeth whitening usually without any side effects. Hydrogen Peroxide can produce certain side effects like gum or tooth sensitivity if used often in high concentration.

Nowadays, it is possible to apply hydrogen peroxide (HP) for in-office-bleaching in concentrations ranging from 6 to 40% [2,3]. ...
