What are the causes of black teeth in adults? Tooth coloration is a situation that we do not encounter for any reason. Although we brush our teeth every day, the teeth will still turn black. So what are the reasons for the black teeth of adults?
Endogenous coloration causes adult teeth to become black. Endogenous coloration refers to the coloration caused by the mixing of pigmented organic macromolecules in the matrix during the development of enamel and dentin. There are mainly drug-related discoloration, and possibly mineralization-related discoloration, and finally systemic factors. Trauma causes blackening of adult teeth. After the teeth are collided, hemorrhage in the pulp chamber can be caused, and hemosiderin deposits in the dentin tubules, making the teeth dark gray.
Such teeth are often still alive, but some are necrotic and require root canal treatment. Exogenous coloration causes adult teeth to become black, and the exogenous coloration on the surface usually comes from coffee, tea, tobacco, etc., so that the pigment molecules only exist in the protein layer on the surface of the enamel, which can be removed by mechanical methods.
Penetrating exogenous coloration causes the darkening of adult teeth. Pigment molecules pass through the many microscopic spaces and pores in the enamel matrix and enter the interior of the enamel, causing tooth discoloration. This discoloration cannot be removed mechanically, only chemically. Drug-induced tooth discoloration is common in chemotherapy patients.
What are the causes of adult teeth blackening? After understanding the reasons, you should try to avoid them in your daily life. If the teeth are stained, you can choose to go to a regular professional hospital for cold light whitening to restore the teeth to white and bright.
