So you've polished those ivories and you want to know how to keep them sparkling! It is wise to stay away from cigarettes, coffee, red wine, and soda. In some cases, the whitening treatment will fade in as little as one month if there is continued use of teeth staining products. In cases where teeth staining products are kept to a minimal, your teeth whitening could last up to a year. It would be best though, to check with your dentist on the best methods to keep your teeth looking white.
After treatment your teeth can be sensitive, especially to hot and cold food or drinks. Try your local pharmacy for products to help ease the sensitivity. Many people use toothpaste for sensitive teeth-which comes in several varieties including whitening!
