Can I bleach my teeth only at a dentist’s office?

Along with professional teeth bleaching carried out in the dental office, there are also procedures carried out in non-professional environments (non-dental contexts such as kiosks in shopping malls, spas, beauty centres, etc.) and over-the-counter products available directly to consumers with a H2O2 content of less than 0.1% or without hydrogen peroxide.

These teeth bleaching or whitening products can be applied with preformed or adaptable trays using a brush or strips and often use lights to heat the gel and have to be repeated frequently (30-60 days).

However, there is no scientific study that supports the effectiveness of whitening/bleaching products that release or contain H202 concentrations of less than 0.1%.
