2. Pigmentation: for example, taking dragon fruit, prunes and other dark-colored food, food pigmentation attached to the top of the gums, can also lead to adult teeth black purple.
3. Lead poisoning: long-term exposure to lead and other peripheral hormones may cause lead poisoning, which can cause the surface of the gums to appear lead-colored, causing the flesh of the adult dental bed to be black and purple.
