Teeth whitening is a process that helps to lighten the colour of teeth. While a number of whitening methods are available today, our dentists favour the “custom tray method” of whitening. This approach involves the once a day (or night) wearing of thin, pliable, custom fit “shells” that hold a small amount of whitening gel. After several applications, teeth will reach their whitening potential. Halifax Dental Group does not typically perform “light activated” or “laser” whitening. Several studies have shown that the “light-activated” whitening products rely primarily on a highly concentrated whitener. Recent studies have also show that the similar results can be obtained with the custom tray method at a fraction of the cost of the light assisted products; significantly less sensitivity is an added benefit.
