3mo I ask because I myself have an underbite and my eye teeth are the only ones that go over my bottom teeth, they're also very pointy like vampire teeth. My teeth are also stained yellow (not as bad as it use to be, it's light yellow) from all the antibiotics I was taking as a kid.
My family nor me myself can't afford to have them fixed, but I will one day. It will require me getting braces until they are straight, then getting jaw realignment surgery.
Depends. Dental hygiene definitely matters for me (brushing teeth, flossing, keeping good care). But I'm not overly strict on the appearance, meaning some people have healthy teeth and have taken care of their teeth for ever, but it still doesn't look like perfect American artificial porcelain teeth.
