Teeth whitening refers to one of a number of techniques including chemical whitening, mild acid whitening, and abrasive teeth brightening that are performed to correct discoloration of the teeth by removing brown and yellow staining. The process of teeth whitening begins by creating a custom fitted mouth tray for the patient. The mouth tray provides a proper fit for comfort and also ensures the proper distribution of whitening solution to the teeth.
Once the mouth tray is created, the dentist provides the patient with materials and instructions to follow through on their treatment. Typically, the teeth whitening session involves keeping the tray and solution in your mouth for between 2 to 3 hours. Occasionally the dentist might even instruct you to keep it in overnight. This process will continue anywhere from 2 to 3 weeks after which you would return to the dentist for a follow-up visit.
