teeth braces

are teeth braces a common thing for adults??

i went to the dentist and he says i can use them bcoz my bottom teeth have become too crowded by wisdom teeth (which he says need to come out too) and he says i have too much over bite.

according to my dentist im still growing.........hmmmm.....i was thinking that by 27 i would be considered a fully grown woman now .......but he says my teeth are still moving around bcoz im still growing!!!!

does this sound right? do i need a new dentist or

has anyone else had braces installed in your late 20s or beyond?
