The teeth are microscopically porous. These pores within the enamel (or outerlayer of the tooth) can collect stains over time. Extrinsic stains from coffee, tea, smoking and normal use can accumulate within these pores creating a discolored tooth. Tooth whitening removes the stains from within these pores. Whitening is less effective with intrinsic stains from medications or discoloration that occurred during the development of the tooth.
Most patients who whiten their teeth notice a difference afterwards. However, the amount of whitening achieved varies from person to person. This is dependent on the type of enamel and the type of stain. Those with opaque enamel and extrinsic stains usually see a more dramatic result than those with translucent enamel and or intrinsic stains.

There are two methods for whitening. In the first method, plastic trays that are custom fit to the shape of the teeth are made. The patient performs the whitening at home by placing a small amount of whitening solution in the tray and wearing the tray on the teeth for a directed amount of time
The second method in an in-office procedure where the dentist places the whitening solution directly on the teeth and activates the solution with an ultraviolet light for a given time. The in-office procedure usually takes an hour and provides for a quicker result than the whitening done at home.
Remember that crowns, fillings, bondings and porcelain veneers do not whiten. Only natural teeth whiten.
