Going into reserves.

Im a prior service army veteran. Long story short my wife decided to join active duty airforce or army as I cleared my process to join coast guard reserve. So I decided to give up and reapply down the road again due to my 3yr old daughter. I also end up getting braces for my teeth.

I been getting second thoughts about join. Recruiter said I can still join as long as I take my braces. Didn't ask about getting retainer. I'm a us customs and border protection officer. Can you guys give me any advices? I guess i don't really have to join but I want to cuz I wanna go BM get enough boat hrs to go apply AMO.
