I just got my braces off today and i just got retainers and i was just wondering if its ok to play with them because they told me to take them off while playing sports
Your orthodontist is probably thinking more along the lines of like baseball, soccer, basketball, anything where you can get socked in the jaw. Doesn't happen too often in paintball but if you are uncomfortable with it just take it out when you are actually playing.
Also, must remember to put it back in again eventually. You definitely don't want to have braces a second time.
I am 13 so this might not help but I am whating till i am at least 16 or 17 to start to play on a team because you have a lot of experince and you will know more people. Trust me I tryed to join a team and it is hard for young players like me to find ones.
