In this article, I want to review the proven, safe method of teeth whitening which we have been using in our office. This is also what we teach our students at USC dental school because it is supported by years of research proving its effectiveness and safety.
Custom Tray Teeth Whitening (Bleaching)
Teeth do have a maximum shade of whiteness than can be achieved, and this varies from person to person. The method we recommend is the safest method to achieve the maximum shade of whiteness possible. It involves the use of a low concentration of carbamide peroxide gel (10%) worn over night for 6-10 hours with an extremely well adapted custom tray. Treatment time varies depending on the initial shade, and certain conditions such as Tetracycline staining may require an extended treatment time to achieve the desired results.
The custom tray is made to form a tight seal around your teeth to keep the gel intimately adapted to your teeth. The precise fit of the tray is critical because using poorly fitting trays allow saliva to dilute the gel material and decreases the efficacy significantly. Also, the proper fit of your trays will prevent the gel from contacting your gums and causing irritation.
Whitening with 10% Carbamide Peroxide Gel
10% carbamide peroxide gel has been used effectively for over 25 years with no long-term post treatment side effects. Higher concentrations of gel may work faster but will not increase the maximum whiteness which can be achieved.
Treatment with 10% carbamide peroxide is recommended for its effectiveness and its proven safety which is unrivaled with higher concentrations of gel.
