Also, with your teeth having so many problems, please make sure with your doctor that your kidneys are functioning fine (lab testing) and your blood calcium is normal.
I'm sorry I did not see this before. Do you have medical insurance? If you do, though they typically don't cover something such as a TMJ splint, they typically would cover non-teeth related jaw problems such as ruling out jaw cancer via oral and maxillofacial specialists. So, if you have medical insurance, ask for a list/look online for a list of their participating oral and maxillofacial surgeons/specialists.
