Teeth whitening is a chemical process
and can be performed at the dentist or by the patient
in their home, using a product supplied by the dentist.
Before the teeth whitening regimen, the dentist creates
a custom mouth tray for the patient. The tray ensures
that the correct amount of solution is used and that
the teeth are correctly exposed to the solution.
Whitening session can last for two to three hours,
during which time you will have the tray and solution
in your mouth.
