Can a person inheirate bad teeth?

Answer 1

Yes. Just as all other health related issues are genetic - bad heart, varicose veins, poor eye-sight, body structure - so are your teeth dependant on your genes. Of course, as with most things, you have ultimate control over how bad, or good, things will go... like, if you're family is cavity prone regular check-ups, and brushing and flossing after every meal (flossing is most important for all mouths), as well as keeping gums can help you fight off the ravages of the "bad genes". It's all random, too. While my brother, who would never brush and floss, never had a cavity growing up, I was plagued... despite my impeccable dental hygiene! He got our mother's good side, while I got my father's bad side... though, I got more of our mother's mouth and tooth structure, and he got our father's less "toothy" structure.
