In-office bleaching procedures are ideal if you want immediate results. The whole process takes about an hour, taking little time out of busy lives. A protective gel is applied to your gums to protect the soft tissue. Then a special light-activated gel is applied to your teeth and light or laser is used to enhance the action of the agent. Finally, the patient receives a take-home gel and instructions to keep the smile bright. The result is dramatically whiter teeth that will last for years.

Tray whitening is a less-expensive and more convenient at-home whitening treatment. The results are more gradual. An impression is taken at the dentist's office in order to create a customized clear tray. Trays are generally ready within a few days, depending, and the patient must follow instructions for how to apply the gel in the trays and how often to use it. Maximum whitening results and a dazzling smile are achieved at the end of the set treatment period. An occasional treatment can be used to maintain the new smile.

Whitening strips can be available at the local store or at dental practices. The dentist will have the best recommendations for your needs.
