Although there are many ways this can be accomplished, the most effective, long-term results occur with a procedure called “home whitening.” This is a dentist-supervised treatment utilizing custom trays made from accurate impressions of your teeth. These thin trays hold & retain the whitening gel comfortably & intimately on your teeth, preventing the saliva from diluting or washing it away. Treatment time varies, but typically a two-week protocol is recommended. The whitening trays are either worn at night while sleeping or, if preferred, a daytime regimen may be used. The trays can then be saved & used for an occasional touch-up when desired.
