Stained or discolored teeth can have a big impact on confidence, and sometimes daily brushing and regular teeth cleanings cannot remove the discoloration. In these cases, there are options like porcelain veneers and teeth whitening services. Porcelain veneers cover existing teeth with custom made, tooth colored caps which are made to last and provide a natural looking smile. They are also resistant to staining. Teeth whitening services can be administered for patients whose teeth are expected to respond well to bleaching. Teeth whitening can only be done on natural enamel so it is important to consider having old crowns and fillings replaced before bleaching is done so that all teeth will match. Also, avoiding foods and beverages which are known to cause discoloration can help diminish staining. These might include red wine, coffee, tea, curry, berries, and other foods or beverages. Smoking and chewing tobacco is also known to cause tooth discoloration.
