Tooth discoloration or the yellowing of teeth is one dental condition which is not unusual for some. This condition is caused by various factors which are indicated below.

Intake of black coffee and tea
Black coffee and tea contain tannins causing tooth discoloration and yellowing of teeth. Tannins are biomolecules commonly found in plants, herbs and trees. These are dark in color and cause stain to a variety of surfaces and compounds.

Smoking tobacco
We all know that smoking is certainly bad for your health; well it is for your oral health as well. Smoking tobacco is another activity causing many bad oral hygiene conditions. This activity also contributes to the disruption of proper functioning of gum tissues.

Too much drinking of soft drinks
Another factor contributing to tooth discoloration is too much intake of soft drinks. This beverage contains large amount of acidic sugar, phosphoric and citric acid. These acids destroy the enamel and make it vulnerable to discoloration.
 
Wine
Wine as a beverage contains chromogens which is a pigment leading to tooth discoloration. Based on a study recently conducted at the New York University School of Dentistry, the teeth exposed to white wine before is extremely stained. This recommends that we should watch our food intake because of the possible unpleasant effect it gives to our body and our teeth.
