Diet and oral habits such as smoking and tobacco chewing discolor teeth. Constant in-take of staining agents such as soda, tea, coffee, dyed foods and tobacco products contribute to superficial stains on teeth that can only be removed through bleaching.

Bleaching can be done at home or at the dental office. Home bleaching kits are convenient for some but are often time consuming and limited in its whitening ability. In-office bleaching takes only one session which more or less lasts for 30 minutes. It is a faster bleaching method that often yields teeth whitening that lasts longer than home bleaching methods. Regardless of whether home bleaching methods or in-office bleaching is to be done, consultation with your dentist is important before starting any dental treatment.
