How does bleaching work?
Teeth naturally darken as we age. Over time, staining may be caused by exposure to coffee, tea, soda, tobacco, and certain foods. Discoloration can also occur because of certain childhood illnesses, medications, physical trauma, etc. A tooth whitening system will remove discolorations with a gentle sustained release action that will oxidize (bleach) stains within your teeth. Your tooth structure remains unchanged. History and research show that most patients treated experience some level of tooth whitening. Porcelain restorations and white fillings do not whiten with bleaching agents. Your dentist will examine your teeth and gums to ensure good oral health. Old fillings may need to be replaced and/or decayed areas treated and filled. An impression of your teeth will be taken to guarantee proper fit of the custom fabricated bleaching trays. The thin, soft plastic trays provide sufficient comfort while bleaching. Once the tray is made, your dentist will explain how to use bleaching gel.
