Why Teeth Turn Yellow

Tooth discolouration may be caused by four factors—extrinsic or intrinsic staining, as well as genetics and aging.

Extrinsic staining happens on the surface of the tooth and can be caused by one’s diet. Dark-coloured foods and drinks like chocolates and coffee are common culprits. Additionally, habits such as cigarette smoking and poor dental practice can also contribute to the yellowing of teeth.

Intrinsic staining happens within the tooth. Some of the factors that contribute to changing the “light-transmitting properties of the enamel and the underlying dentin” include medications and excessive fluoride ingestion.

Moreover, genetics and aging are two lesser known reasons for why teeth can turn yellow. Read more in this informative Live Science article.
