Grinding teeth and biting tongue.

[Scarecrowrowboat]

I have a real problem with biting my tongue and grinding my teeth on it while biting.
I've already lost a tooth and in danger of losing another and an implant. I only do it during day time. I've tried mouthguard and I've tried hypnotherapy.
One interesting thing I noticed was that this behaviour and compulsively pulling out my hair almost completely stopped during all my pregnancies. I was wondering whether anyone had experience of this or knowledge of why this could be as it could be the key to saving my teeth.

I do this as well as jaw clench. I find it is worse during periods of high stress. All my teeth are flat & I even managed to bite a hole in my mouth guard.

I have ADHD, and apparently it is a common stimming behaviour/tic.

Clearly, I don't know if this applies to you OP, but I have heard that hair pulling can also be a trait.

It's so frustrating isn't it just not being able to stop even when your teeth are being slowly ruined!
Yes I have ADHD and am autistic so they probably are stims but I'm just confused that these behaviours stopped every time I was pregnant. I just had no urge to do either. It makes me think somehow hormones play a part but that seems so strange.
