I've considered this actually, but I wouldn't spend so much money on something so minor unless it was really affecting my standard of living, which it isn't, I'm just a perfectionist and it's mildly irritating that I can't do anything about having overbite. However, if you feel that it is affecting your confidence and basic standard of living, social issues etc. I would say go for it. Even if it is really minor, you might post a picture in here that I considered to be completely normal and that you didn't need braces or any correcting treatment, but you might just think the opposite. The answer is, unfortunately...'if you want to do it, do it' haha.
