Another option for whitening is the professional home bleaching method. It requires a dental tray, which can be customized to your mouth by getting a fitting from your dentist. The tray with bleach inside can be worn overnight or for an hour each day. Laser bleaching is another whitening procedure. The laser light is used to accelerate the whitening solution.
Porcelain veneers are another way to whiten teeth.
This option works best for teeth that are discolored because of genetic, medical or environmental reasons. The procedure is done in the dentist's office. The tooth is roughed up, covered with glazed porcelain and then the porcelain is bonded to the tooth. This procedure can be used in conjunction with bleaching. Whitening toothpaste is perhaps the cheapest option.
