Teeth Grinding and OCD: Serious Damage to My Mouth

Has anyone else caused serious damage to their mouth from grinding their teeth or chewing their inner cheeks? Part of my OCD is related to me having to do those things in a specific pattern, and I do it around half the day doing it most days. It's gotten to the point where I don't even notice I'm doing it until I catch myself randomly or something especially painful happens. My teeth are beyond repair. I get cavities filled only to wear away my filling, and I've chipped one of my teeth doing my rituals. My inner cheeks also have huge skin tag-like things by my canines, and then theres a straight line of white, damaged back where my teeth meet. Not sure what to do about it beyond a therapist. I don't want to be on medication if I can help it, just personal preference. But I am pretty worried about what my mouth will look like in 5 years.
