What causes black teeth in adults?

Answer:
Teeth can be stained a multitude of colors but some people end up with teeth that are literally black.


From Wiki:Ohaguro (お歯黒?) is a custom of dyeing one's teeth black. It was most popular in Japan until the Meiji era, as well as in the southeastern parts of China and Southeast Asia. Dyeing was mainly done by married women, though occasionally men did it as well. It was also beneficial, as it prevented tooth decay, in a similar fashion to modern dental sealants.


Users of Betel Nut can also end up with teeth stained very dark red and in some cases black. Almost 10% of the entire world population chews Betel Nut.


There are many substances that when chewed can stain and even blacked your teeth.
