My parents had bad teeth and ended up with dentures so I will too, right?
No. Your parents gave you your eye color and a lot of your other characteristics, but luckily you aren’t stuck with their bad teeth. There are a small handful of genetic disorders that cause teeth to form incorrectly, but these are pretty rare. One important thing that affects your teeth that is handed down from parents to children is habits. You tend to eat the same sort of foods as your parents (as a kid you really don’t have a choice, do you?), and if they didn’t put too much importance on brushing and going to see the dentist regularly then you might not either. For the vast majority of people the health of their teeth depends on two things: diet and home care (brushing and flossing). Most dental problems can be fixed or avoided altogether with regular dental checkups and good home care.
