What other tooth-whitening methods are there?

There is now laser whitening or ‘power whitening’. During this treatment a light or laser is shone on the teeth to activate the chemical. The light speeds up the chemical reaction of the whitening product and the shade change can be achieved more quickly. Laser whitening can make teeth up to five or six shades lighter. This treatment usually takes about one hour and you must be seen by a qualified dentist before starting treatment.
