Dentist-prescribed home whitening is a new bleaching alternative. It combines the convenience of at-home bleaching products with the assistance and expertise of your dentist. Here's how it works: We take a model of your teeth and use it to make a custom-fitted tray. Then we provide you with instructions for application of the tray, which contains bleaching gel. You wear it each day or night for as little as 1 hour, only returning to have the procedure monitored. Patients often see results after the first day. A significant change can be noticed in as little as 3 days. Maximum results will be achieved with use over a 4 to 6 week period. For further information, please ask any of the dentists or office staff here at Markham 7 Dental in Markham.
