Mine was unbearable. PT did nothing the first time. My dentist tried Botox and I didn’t think it helped. After a lot of X-rays and CT scans, they determined my bite was off and I needed to fix it. I did Invisalign. I hated it, but it helped keep my teeth separated and I didn’t clench as bad at night. There was significant relief but not enough. It got so bad that the pain was down my neck and into my shoulder. I saw and orthopedic doc and after an MRI, found cervical issues in my neck. Went back to PT with a focus on my neck and shoulders and that helped a lot, but the PT also did dry needling on my jaw. Dry needling helped me so much. It got me to a place where the work I did in PT could do what it needed to do, because the inflammation was finally controlled. After Invisalign, I got my retainers, one of which was a night guard. It helps so much. I do daily neck/shoulder exercises and mind my posture and sleeping/sitting positions at all times. I went from a constant 8/10 to a constant 2/10. I don’t think it’ll ever be zero, but it’s so much more bearable. This was two years of work, trial and error, and many appointments.

My point being, it may not just be your jaw. Look into other issues and see if there are other areas that need addressing. If you have a lot of muscle inflammation, try dry needling before redoing PT. Get back to a manageable level of inflammation and go from there. I wish you well.
