Believe me, I think most if not all of us have hesitated for one reason or another. For me, the thought of the extractions was the major issue. I had to have 3 extractions and I was SCARED of it! The process, the pain, and the aesthetic result aren't nearly as bad as I imagined them to be, at ALL.
Do I absolutely LOVE my braces? Ummm.....no. I never imagined I would, despite some people on this forum who are lucky enough TO be in love with them. I've had mine on for about 6 months now and the changes have been amazing. If I didn't have some hangup about reaching into other people's mouths, I would consider a career in orthodontics, because I think it's SO FASCINATING how it all works, to be honest...
For the first week, I thought that there would be no way in H*** that I would be able to get through it. It felt completely foreign and uncomfortable, and I felt ugly and had a lisp.....I'd resigned to be utterly single, self-conscious and in waiting mode to resume a normal life until they came off. I cried, mourned...it sucked.
But....virtually nothing has changed in a negative way; it's all been positive. I've gotten used to them to a degree...not COMPLETELY but it's certainly tolerable and most of the time I really don't think about them.
Once you get them on, and get used to them (that's the key...), I think you'll be fine and you too will realize that all of the mental anxiety you had pre-braces, although understandable, was mostly in vain. If it were THAT bad, no one would do it.
Good luck, but...you probably won't need it.
But these 2 months have gone by faster than I would have imagined in the beginning. And I'm still in the novelty phase of the excitement of small movements.
