Im a 28 year old male. I got a few questions and hopefully some one could share some light.

1. Is it ever too late for an adult to have the teeth straighten or at least position improved? If so, what are the commonly used options?

2. All, my wisdom tooth are out and intact. Some growing in an awkward position, some normal, but of course it affects the other tooths. What I would like to know, is whether shifting occurs throughout the adult hood.

It is never too late to get your teeth straightened, usually done with braces. However, after the braces come off, you have to wear a retainer because your teeth have "memories" and would tend to move back to their original crooked position if you didn't constantly wear your retainer - day and night at first, then probably just at night later on. A lot of adults have braces. I did when I was 30 for two years. Best thing I ever did.
