Teeth can become discolored and stained on the surface for many reasons. Some of the most common causes of surface stains include:
coffee and tea consumption
energy drink consumption

smoking or chewing tobacco
Other discoloration issues can occur when teeth are damaged or badly decayed, or after a root canal is performed.
