I had a wisdom tooth extracted over a year and a half ago. It had a cavity which had broken down to my gumline. The dentist just did a simple extraction, no surgery. The shot of novacane went so deep into my gum that I had soreness for weeks afterwards in my jaw bone. I have had earaches and jaw pain on that same side ever since. Our hospital offered a free oral clinic a couple of weeks ago and I went to have a swollen place under my tongue looked at. A dentist there found a knot on the very back of my jawbone that he said felt abmornal. He called in an oral surgeon who felt of it and said it was a bony ledge. She said I had muscle trauma from grinding my teeth so bad at night. My question is, can this cause my ear to hurt constantly. My family doctor says my ear looks fine inside and there's no reason for me to have an earache. My ear has hurt off and on since the extraction.
