Exogenous coloring:

Exogenous coloring is due to the presence of a variety of bacteria on the surface of the teeth, which secrete a number of viscous substances on the surface of the teeth, tea stains in the daily diet, smoke and some minerals in drinking water and minerals in human saliva adsorption Plaques and calculus form on these stickies, gradually whitening or darkening the teeth.

Endogenous coloring:

Endogenous coloring means that the coloring substance enters the tooth structure and causes tooth discoloration. This discoloration may be due to coloration caused by the penetration of some of the body's degradation products into dentinal tubules (such as bilirubin produced during jaundice, degradation of hemoglobin after pulp necrosis, etc.) after tooth development is complete.
