Why Are My Teeth Yellow?
Teeth tend to naturally discolor as we age, but besides that, there are several different ways for teeth to become discolored. Some of the causes of darkened teeth are genetics, antibiotics, and certain foods. Internal tooth discoloration is caused by changes in the enamel of the tooth and the dentin. External tooth discoloration is caused mainly by foods and tobacco. The main causes of tooth yellowing are smoking, foods with tannins, coffee, tea, carrots, oranges, and other foods. To avoid excessive yellowing, stay away from these factors, and brush daily.
