Tooth whitening is the number one requested and performed cosmetic dental procedure. Tooth whitening is a procedure that lightens teeth and helps to remove stains and discoloration. A thin coating forms on your teeth, throughout the day, which attracts stains. The tooth's enamel contains pores that hold stains. Cavities need to be treated before teeth are whitened because the whitening solution can penetrate decay and reach inner areas of the tooth, which can cause sensitivity. Receding gums can cause roots to become exposed. Whitening will not work on exposed tooth roots, because roots do not have an enamel layer. Whitening also does not work on tooth restorations such as crowns or veneers.
Whitening can be done in the dental office or at home.
