Should I bleach my teeth?

Private practitioner, Dr Paul Gallop, replies: You can have your teeth bleached by a dentist or do it yourself using a dental surgery home bleaching kit.

The light is only shone on each part of the tooth for a few seconds, but the whole process takes two hours. Your teeth are then rinsed with water.
