Whitening methods include :
- In-office bleaching solutions (carried out by your dentist).
- Home Bleaching solutions (either supplied by a dental professional or available over the counter).
Bleaching solutions generally contain hydrogen peroxide or carbamide peroxide, which bleaches the tooth enamel to change its color.
Bleaching solutions may be applied directly to the teeth, embedded in a plastic tray that is placed on the teeth or use a gel held in place by a mouthguard.
The effects of bleaching can last for several months, but may vary depending on the lifestyle of the patient.
