OP I'm a kickboxer and I have to use a mouthguard which is made out of plastic, I'm trying to find a supplier that makes natural rubber mouthguards but until then, what should I do? I read that you can remove xeno-estrogens from plastic by using salt water and alcohol

Remove as many toxins from what you end up using as possible, but the thermoplastic material they use in almost all mouth guards is ideal for fit and there's no natural material I can imagine having the same properties for fitting so perfectly. maybe make a clay mold of a prefitted plastic one that you currently use and pour in pure high quality silicone. Idk if it would be perfectly as fitted as the plastic ones even then. Alcohol may make the plastic more brittle but test it for yourself. You could spar with no mouth guard if you worry enough about plastics or prefer the advantage of being able to breathe better while fighting over the added security of the mouth guard. I sparred with no mouth guard in Muay Thai because I get winded easily with mouth guards restricting my ability to breathe through my mouth and I never got serious injuries to my lip or jaw but I wouldn't advise it as a concussive blow to the head is most likely way worse than plastics getting to you. I haven't studied the effects of mouth guards or the type of plastic they use though so try out various things
