The professional whitening that we offer through our office is a wonderful way to remove stains and improve the overall appearance of your smile. There are two methods for whitening. One is to remove stains caused by drinking coffee, tea, wine, and also smoking. The other is to bleach discolored teeth (we commonly called bleaching as whitening.) caused by age matters. We apply "Air Flow" technique to remove stains, in which special powder and pressure work as remover. For bleaching, we have office power whitening using a laser technique, traditional home whitening and dual whitening technique which is a combination of office and home whitening. If you have a difficulty wearing mouth trays over a few hours, office whitening would be the choice. However, we now know dual whitening is the most effective and powerful whitening method to have satisfactory results.
