Why peroxide-free?

Bleaching agents like peroxide have an aggressive whitening mechanism called free-radical oxidisation, which has some detrimental side effects.

Among these side effects are sensitivity, irritated gums, and the loss of minerals in the tooth. Dentists limit these reactions with in-chair treatments, but at-home treatments are riskier.

We use Pentasodium Triphosphate (PT) as our primary whitening ingredient. The PT method is a safer alternative to peroxide because there are no free radicals released. As a result, no damage is done to the gums or enamel.
