You'd probably be looking at ProTech Mouthguards
or Gladiator Mouthguards
. Both are pretty spendy, and I know that the ProTech has gotten real popular lately (a lot of CA based fighters are going with them). However, I've been reading a lot of negative posts at various fora about how long it takes to actually get the mouthguard after ordering (and paying) for it. Don't know too much about Gladiator Mouthguards to be honest.
In any case, you're probably looking at a few hundred dollars for a custom guard. If you're just starting out, save the case and get yourself a plain mouthguard. Use the rest of the cash for other equipment you really need.
It doesn't matter if you agree or disagree
