Regardless of how well you care for your teeth, it is inevitable that, over time, some yellowing or discolouration will occur. This gradual change can be caused by ageing, substances that stain your teeth (such as coffee and tobacco), excessive fluoride, or the deterioration of a tooth’s nerve. A tooth whitening treatment can be performed either as an at-home, dentist-supervised process or in the dentist’s chair. While neither of these methods stops future discolouration, these tooth whitening treatments bring about whiter teeth and help create a brighter smile.
At Home Teeth Whitening
The most popular method of tooth whitening is the at-home, dentist-supervised option. During your visit to the dentist for tooth whitening, he or she takes a mould of your teeth and creates a comfortable, customised mouth tray. The mouth tray holds a mild solution whose main ingredient is carbamide peroxide, a substance that reacts with water to release a non-toxic bleaching element (hydrogen peroxide). The mouth tray is placed inside the mouth and sits only against the teeth, thereby avoiding contact with the gums. Patients can choose either to wear the mouth tray throughout the night or for stretches that last from two to four hours. When the mouth tray is worn throughout the night, the tooth whitening treatment lasts one to two weeks. Patients with more sensitive teeth may opt for the latter approach, which lasts three to five weeks.
