Various methods exist for tooth whitening. Dental on Clarke uses a gentle whitening method which involves the taking of dental impressions and the construction of customised whitening trays. Those customised trays are then worn in your mouth with a whitening gel inside the customised trays. The time taken to whiten teeth varies according to the patient’s individual circumstances. This whitening method is beneficial because it produces less tooth sensitivity than some other whitening methods. Tooth whitening will not alter the colour of dental fillings, crowns or veneers, so you should have a thorough discussion with your dentist about the expected outcomes of any whitening method. For many patients, however, tooth whitening can produce a pleasing improvement in tooth colour and bring your natural tooth structure to its whitest potential.
