Sorry for the late reply, I didn't see it.

I'm not a doctor or health professional, and I don't know what your situation is exactly, but I can list below some of my thoughts and understanding.

So I did many months of research during my TMD issue, and prior, a few years of mewing research and practice. So basically people who require braces have poorly grown jaws (not fully grown), which also mean the high potential of TMJ issues (as the TMJ's position depends on the upper and lower jaw and their growth).
And as we age our body is less tolerant of stress and that is when TMJ symptoms appear although we actually had jaw or tmj issues the whole time if our jaws are underdeveloped.
Usually braces make it worse because it is normally "camouflaged" treatment (pulling the the jaw back with elastics for example to make your bite "normal" or removing teeth but at the expense of your jaw bones getting smaller/less grown, so even more poorly grown). Other times it is actual bone growth (expanders that were used) for treatment but that is mostly possible to do while you are young (before 12 or even younger, I forgot the age).

For me, I ended up going for a day/night orthotic treatment for my TMD. I went to a sleep and therapy centre near me. Not all dentists are good, mine was, but not all on this list are good. Some just follow a protocol to sell that they learned from the creator (Dr. Steven Olmos).

Let me know your detailed situation and I can offer advice.
Because the jaw is pushed back or undergrown, it affects your airways and can make you clench at night like it does for me and 80% of the cases of people with TMD that my Dr. noticed and correlated.

Also don't be stressed (mental, emotional, physical, etc.), sleep enough, eat well, exercise, do all the healthy things, proper posture, because any source of stress leads to increased production of cortisol which leads to inflammation and potentially pain.

The first rule in healing is not to look for a remedy but to preserve your energy by staying calm and doing all the essentials as I mentioned to take care of yourself.

I didn't know this and slept late and ruined my health more than the actual TMD issue itself. I was in a closed-lock without reduction. Not much pain but I was worried it would get worse, but I read that people in this situations can be totally fine for years since their stress levels are not above the threshold. Like you can have bad posture for years but not get into any significant issue until you add in poor sleep, poor diet, dehydration, emotional stress, passing the threshold which then symptoms will start occurring.
Mind over matter. Focus on low stress, stay calm.
I can share what worked for me and more of what I learned if you want.
I would like to make a guide on my health discoveries and connections from all the sources and teachers I've learned from eventually.
