I recently got braces and after having my mouth shredded last night I've decided I want to get a mouth piece. I grabbed one of the spare mouth pieces that I brought from the States (I'm in Brazil) and molded it. The thing is, it fits very tightly and it's a pain in the ass to get off, I'm kind of worried that I might peel off one of the brackets and that would not be ideal. My questions is, does anyone have experience with molding a regular mouth piece while wearing braces. Also, does anyone have any tips of tricks for preventing cuts in your mouth while grappling? Thanks in advance.
