Teeth whitening often provides excellent results, unfortunately, they will not last a lifetime. While the longevity of the results varies depending on each patient's individual care routine, teeth whitening results can last anywhere between several months to several years. The key to sustaining brightened teeth is to maintain a regular oral hygiene routine and receive routine dental checkups and rinsing your mouth after consuming foods and drinks prone to staining, such as coffee and tea. In addition, it is advised to quit smoking in order to prevent new nicotine and tar stains from appearing.
