Went to TMJ specialist, and he thinks since it hurts on upper, then lower and into jaw
, that possibly the ligaments of the root-canaled tooth are inflamed, from
grinding/clenching on it. He took nightguard out of occlusion(small amt). He put me on motrin 800/3 times day, and a muscle relaxant to sleep with. Told me not to chew on that side either. I have had some relief about 5%, but tried a small amt of chewing on it and caused flair/soreness of pain.
