There are several methods available for bleaching the teeth: in office, overnight or daily. For overnight bleaching, we make an impression of your teeth and create a mouthguard that fits your bite. Each day you fill the mouthguard with a small amount of bleaching gel and wear it overnight or for a few hours during the day. The overnight bleaching process takes approximately two weeks.
Other over-the-counter daily bleaching products are available, but it is important to use any bleaching product only under the supervision of a dentist. To achieve the whitening results you desire, the ADA recommends that you seek the professional advice of a dentist, including examination and diagnosis of the cause of tooth discoloration, before you begin any bleaching program.
