After playing for a while (less so when im playing for atleast a couple hours a day) my lower lip gets irritated and raw close to my gums. Its not so much from a biting pressure but more from a horizontal pressure pushing my out turned lip into the edges of my teeth. I have fairly sharp (almost serrated) teeth. I've been told so by my dentist and when mentioning that they can cause problems for sax he mentioned there was the option of filing them if the problem persists, but I'm 17 so I'd rather not jump to that this early. I've looked around SOTW and people have suggested things like dental tape and homemade toothguards (cut up mouthguard material formed to your teeth). I was wondering if anyone had other ways of protecting their lips from this kind of damage over the years, and if anyone's gone as far as to file their teeth for this reason. And before you ask, I play Rico 4's on a JodyJazz Jet 8 (.110) and Otto Link STM (Opened to .117). Thank You!
