Tooth whitening, also referred to as tooth "bleaching", has become a very popular and satisfying way to improve the look of your smile without being invasive. There are many reasons why teeth become discolored. The sources of tooth discoloration include 1) the daily use of stain producing foods and beverages such as coffee, tea, wine and dark colored soda, 2) the use of certain antibiotics at an early age while permanent teeth were developing, and 3) the aging of teeth which causes the enamel to become thin and thus the inner yellow tooth layer to become more noticeable. All of these causes are successfully treatable with tooth whitening. Clifton Park Dental offers bleaching kits, in various strengths, that patients can conveniently use at home for whatever length of time is needed to achieve the desired result. In order to use these professional grade whitening kits, ( that's right- these kits are only available through a dentist due to the higher concentration of bleach and cannot be bought over the counter) a patient must first have an appointment with the dentist to take impressions of the patient's teeth. These are used to fabricate custom fit bleaching trays that fit the patients teeth precisely and hold the whitening material against the teeth.
