MrsBouy grinds her teeth, been doing it since a teenager. She’s not stressed, nor anxious it’s just a “thing” she does. I can see the link to stress, but it’s not the only cause. Sometimes folks just do stuff like that, I suck my teeth and I’m not stressed either.
During a routine dentist visit about 5 years ago she was offered a guard, seems she’s been wearing down her rear teeth an bit too much. After a couple of fittings she came away with the guard, tried it for about 3months all the time before complaining about it interfering with her jaw movement and said it felt odd (as you’d expect). So it went in the bedside draw, occasionally it would come out and she’d wear it then for months at a time not.. over the last 2years she’s been wearing it on and off and it’s helping a little…
She does suffer jaw pain, both with it in and without it in. It seems not to make any difference to that aspect.
The guard wasn’t cheap, IIRC it was at least £300…
