BLEACHING TEETH DENTAL QUESTIONS
Darkened or discolored teeth can be lightened by the application of chemicals. For many years this has been accomplished in the dental office with hydrogen peroxide. Recent advances now allow the bleaching teeth process to be done by the patient at home. The chemical is placed in an appliance which fits over the teeth. The amount of whitening one obtains during bleaching is dependent upon; the length of time the tray is worn, and the susceptibility of the teeth to the bleaching agent.
