There are several methods available for whitening teeth: in-office, overnight or daily. One session of in-office bleaching generally lasts one and a half to two hours, and you can read or relax during the treatment. 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 an hour during the day. The overnight bleaching process takes approximately two weeks.
Other over-the-counter daily bleaching products are available. The benefits of products like these is that you can start and stop your bleaching routine as sensitivity develops. In office whitening can lead to greater sensitivity since it is more of a shock to your system. To achieve the whitening results you desire, the CDA 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.Posted by
