Why Do Teeth Become Discoloured?

The yellowing and darkening of the teeth is a natural process that many people will experience, although it can be influenced by a variety of factors.

Smoking, failure to brush your teeth properly, regular consumption of foods and drinks rich in tannins (including tea, coffee, some berries and other fruits, nuts, legumes and wine), exposure to certain chemicals (some found in fairly common medicines) and the natural wear and tear to the enamel that comes with age can all magnify the effects.
