Bleaching methods employed by dentists generate a similar result to laser treatment in that the effects are immediate. Instead of using a laser light to expedite the process, however, dentists will rely solely on a peroxide-based bleaching solution to do the whitening work.
While there is no question that solutions like carbamide peroxide work there is something to be said about the instant whitening effect – it might not be as significant as you think. Sometimes teeth can become dehydrated during the bleaching process and are temporarily lightened as a natural result. Once they come into contact with saliva again, they become re-hydrated and the lightening effect wears off.
This is why some dentists require patients to follow up their in-office treatment with a home-based whitener. Treatment sessions vary, depending on how discolored your teeth are. It may take between 2-6 visits to your dentist to acquire decent results. A tooth whitening cost can range from between $600-$2000 per treatment (not including any extra at-home whiteners).
