Actually yes, when it was quite an issue I made sure I sleep on a high pillow. Just by mechanics it's more difficult to chew on your teeth. Also back then I only slept on either multiple pillows or thick pillows that are meant for sofas to have the head higher, just by mechanics it's more difficult to chew. Also I started the habit to eat chewing gum regularly, it makes the jaw muscles more tired at night. And, holding your head up high during the day helps. Especially when sitting on the computer, I highly recommend using an external screen, so your head is straight.
That in combination was already a game changer.
Also I started the habit to do light sports at least once a week, although that was mostly because of back pain. The bruxism practically vanished after I went to the psychologist to treat my anxiety. It was a treatment without pills, just talking and learning new methods. In my case it was a Systemic Therapy (I think combined with CBT - though I'm not sure) but YMMV and I think you need to choose someone you're comfortable with. For me the priority was to pick someone that I'm comfortable with, that seems to be specialized in what I think might be the overall issue and that seems to adhere to modern methods. Whenever I feel tense when going to sleep, I do Progressive Muscle Relaxation (PMR) which was a recommendation from the Psychologist. There are audios on the internet which guide you through this, takes 10-15 minutes but now I just do it myself in 2 minutes. It's kind of a non-issue for me now, I cannot remember the last time I woke up with my teeth hurting because of that, the last series must have been years ago.
My dentist noticed some wear on my molars right around the time I started experiencing a bunch of minor issues: xerostomia (dry mouth), excessive salivation (strange to have at the same time as xerostomia), jaw fatigue, teeth clenching during the day, and an abnormal awareness of the position of my tongue in my mouth. These were among the many low-priority bugs I'd filed against my body as I was recovering from chemotherapy.
I started chewing gum to help control the xerostomia, and it became a habit. Over time, I believe I actually strengthened my jaw muscles enough to make the bruxism worse, leading to a vicious cycle of needing gum chewing to alleviate the discomfort from constant jaw clenching. This went on for many years.
About a year ago, after changing nearly everything about my daily routine to narrow down the cause, I stopped chewing gum, cold turkey. I replaced it with Tic-Tacs, resolving never to chew them. After a couple months I gave them up, too. While the bruxism and jaw clenching occasionally come back during times of work stress, it no longer seems to be a chronic condition, and my mind has restored enough muscle memory of what a normal mouth feels like that when I notice it's coming back, I can will myself back into a comfortable state again.
Hard to say whether the gum really was to blame. but for me, when I stopped was when I regained control.
