I have TMD and all my life I’ve had a habit of clenching my jaw. I used to grind my teeth but through steely determination I’ve managed to stop that. Jaw clenching OTOH... I do it in my sleep and it wakes me up throughout the night.
I had a custom-made guard from the dentist but it only makes it worse, and from what I’ve read a lot of dentists don’t like prescribing them anymore for this reason.
Aside from the soreness and aching throughout the day, my masseter muscles are enlarged and make my face look rounder than it is
