The causes of teeth discoloration can vary and are generally classified into external and internal factors.

External Factors


Teeth discoloration can be caused by pigmentation on the surface of the teeth due to external factors such as eating, drinking, or smoking. Black tea, green tea, coffee, wine, and chocolate are the typical types of food that can easily cause teeth discoloration.


Every time you smoke, small amounts of nicotine and tar in cigarettes accumulate on the surface of your teeth, making them look extra yellow and darker.

Internal Factors


The enamel, the outer part of the tooth, may wear out, causing the inner dentine to be visible, which may make your teeth look more yellow.

Tooth Trauma

When your teeth are affected by external damage, foreign substances formed from the destruction of blood cells, can stain the teeth on the inside, causing discoloration.

Root Canal Treatment (Endodontic)

Inadequate/ineffective root canal treatment may leave some necrotic tissues within the cavities, causing teeth discoloration. Sometimes discoloration can be caused by a bacterial infection or dental filling material, after receiving root canal treatment. 


During the tooth formation stage, dental discoloration may occur due to inadequate ingestion of various compounds such as drugs and heavy metals. (ex: tetracycline, fluoride, etc.)
