I am having mouth pain in the back on the left jaw, upper and lower after having a tooth prepared for a crown by my dentist. At first my ear was sore on the inside and up my temple to above my left eye. I went to my medical clinic for urgent care on Saturday. The doctor said it was infection and gave me amoxicillin and said to rinse my mouth with mouth wash every six hours. That took care of the ear, temple, and pain above the eye. I still have the jaw pain, can't open my mouth far enough to get a spoon in, and when I chew I have pain (8).
