Pain in the tmj and tooth. All this followed with eye pain. No visible cavity on x-ray. 4yrs ago I put dental bridge over 23 teeth. What to check?

Eye check. This could be referred pain from your TMJ to your eye: but see eyeMD for refraction, Pentacam/or check of angle to be sure you do not have narrow angles & dilated exam; if all ok, it is likely referred pain.
See Prosthodontist. See the expert - the Prosthodontist - for evaluation and treatment. Occlusion (bite) most likely cause. Are you wearing an occlusal / night guard ? You might have worn down your natural teeth secondary to clenching / grinding which might warrant the restoration you described. Same thing can be going on now. See the expert. Good Luck.
