A number of professional teeth whitening options are used today. In all of these treatments, a similar basic process is used to eliminate or greatly reduce discoloration from the tooth surfaces. Here is how these procedures work.
Gels used for professional whitening are all have a peroxide base. Most of these gels contain hydrogen peroxide in concentrations higher than what is sold on store shelves. Some treatments from our cosmetic dentist in Northridge, such as Zoom whitening, also contain carbamide peroxide to boost the effects.
Oxidation is the key to how bleaching gels are able to clear stains off of teeth. When the peroxides make contact with the pigments that have settled on the tooth enamel, the chemical reaction of oxidation occurs. After oxidation is finished, the pigment particles are smaller and lighter colored. Activation methods, such as lights, cause oxidation to happen more rapidly.
Because whitening gels must make contact with particles in order to oxidize them, the gels only work on discoloration on the outsides of teeth. These include most stains resulting from coffee, tea, wine, chocolate, and tobacco. Patients can schedule a consultation with our teeth whitening dentist in Northridge to learn more about our whitening treatments.
