Man, I am 16 and I am having an issue similar to that, but I don't have braces. My front tooth feels a tiny bit wobbly and i'm terrified of having it fall out. I don't know what to think and I have to wait for two days because my mom is going out of town for work so I can't go to the dentist till she gets back. I'm so scared. I love my teeth!
Trust me i know the feeling and im 14. Either go to your dentist and ask for advise. You might get a false one but until your 18 you will be able to get it permanently placed. It could simply be paranoia. I think mine are wobbly but it could just sort its self out in the future.however my opinion is get it checked out there is no harm in that.
