Dental bleaching or tooth whitening is a very common procedure in cosmetic dentistry. As a person ages their teeth may become darker due to changes in the internal structures of the teeth and also from staining by bacteria, foodstuffs or tobacco use. Having white teeth has become high priority for many patients, so they seek ways to brighten their smile. One of the best and most convenient ways to dramatically whiten your teeth is with a home bleaching kit.
Tooth whitening is not permanent. A touch-up maybe needed every several years, and more often if you smoke, drink coffee, tea, or wine.
Reasons for tooth whitening:
Fluorosis (excessive fluoridation during tooth development).
Normal wear of outer tooth layer.
Stained teeth due to medications (tetracycline, etc.).
Yellow, brown stained teeth.
What does tooth whitening involve?
This type of tooth whitening usually requires two visits. At the first appointment, impressions (molds) will be made of your teeth to fabricate custom, clear plastic, trays.
At your second appointment, you will try on the trays for proper fit, and adjustments will be made if necessary. The trays are worn with special whitening solution either twice a day for 30 minutes or overnight for a couple of weeks depending on the degree of staining and desired level of whitening. It is normal to experience tooth sensitivity during the time you are whitening your teeth, but it will subside shortly after you have stopped bleaching.
You will receive care instructions for your teeth and trays, and be encouraged to visit your dentist regularly to help maintain a beautiful, healthy, white smile.
