Professional tooth whitening- this is a highly effective way of lightening the colour of your teeth. It does not involve the removal of any tooth structure. The whitening product is applied using a specially made tray, which fits into the mouth like a gum shield. Initially, you will probably need two or three visits to the practice but once we have started the treatment, you can continue the treatment at home. You will require regular applications of the whitening product over a period of 2-4 weeks for 30 minutes to 1 hour at a time. Treatment results may vary depending on the original shade of the teeth.
