I got braces when I was 30. My family could never have afforded them for me, as a kid. Was very self-conscious about overbite. They were removed 3 1/2 years later!!! Four teeth were extracted to allow for moving the others around, as well as four wisdom teeth before the braces went on. I never regret having the braces, am pleased w/the results. They've stayed pretty well in line for 13 years now, only wore the retainer for about a year. My husband HATED the braces. When I had to wear the neckpiece for 12 hr a day, he insisted I wear it during the day, at work, so he wouldn't have to look at it at home!! Ah, well, I survived. I honestly thought of writing a book of all the weird comments folks came up with when they saw I wore braces. I actually had fun with the comments! You can probably have predicted this: I say if you want to get them, go for it. It WAS uncomfortable when the wires were re-shaped (people always say the braces were "tightened."); I learned how to chew gum even w/the braces, so it wouldn't get caught in 'em (am an AVID gum chewer, and ALL the instructions say to NOT, absolutely NOT, chew gum with the braces on!!), and I think the gum-chewing actually helped get over the soreness after the q six week wire re-shaping episodes. Just my opinion. I got to where I'd cut up all my food (burritos, sandwiches, apples, etc) into small pieces to eat, rather than just bite into it and face cleaning all the crevices, nooks and crannies in front afterwords. Be sure and keep things CLEAN (brush, swish, floss).
My friend's mom got braces when she was in her 50's!! Good luck with the decision!
