Tooth whitening lightens teeth and helps to remove stains and discoloration. Whitening is among the most popular cosmetic dental procedures because it can greatly improve how your teeth look. Most dentists perform tooth whitening. Whitening is not a one-time procedure.
The teeth are then coated with the whitening solution on the front surface of the tooth. Your office may choose to use either hydrogen peroxide or carbamide peroxide as the bleaching agent. Many whitening products require a curing light or laser to be used to add heat to the solution to activate the peroxide.
