I had 20 crown veneers done (10 up and 10 down) it has been one month and I am experiencing chronic jaw & full mouth pain and cold water sensitivity. I recently had a severe neck muscle cramp and was. The Dr. did an x-ray and confirmed that there is nothing wrong. He gave me a night guard to wear as I might be experiencing sleep bruxism after the crown veneers. Can you help me in diagnosing my problem? Is it in the veneers themselves? The glowing material used? my digastric muscle?
