how can i whiten my teeth

Bottle. The goal is both to whiten the teeth and to make them more permeable to oxygen.

Now with your teeth more receptive to the oxygenating effect of bleach, you return to the dentist's office this time for a standard power bleaching session with retractors and rubber dam.

Depending on how deeply the teeth have been bleached using the home trays, your dentist will use a nine percent or a 27 percent hydrogen peroxide solution. To maintain maximum whiteness, you continue using your Deep Bleaching Trays overnight once every one to three months.

If you drink red wine on a daily basis, you are advised to use the trays overnight once every two weeks. Dentists who use the Deep Bleaching regimen say it provides permanent deep-whitening if patients follow maintenance instructions.
