I had my wisdom tooth removed 3yrs back. The dentist hammered at it for 30 mins because the tooth wont come off easily.I am told the nerves around the hammered region are damaged to some extend and now i have this slight pain every time i swallow saliva. The pain is not there when i swallow food or drinks. However my ear is also affected as i now have this pain on the side where my tooth was extracted.What is worrying me is the pain has been with me for this 3yrs and with my limited medical knowledge, iam scared whether this prolong pain on the inner side of my jaw and ear may lead to cancer. Will somebody kindly educate me? Thanks.
