I am a 92-year-old male. A couple of years ago, my dentist installed a crown on the third molar ( wisdom tooth ) in my lower left jaw. Afterward, I started complaining of pain in the area and even some in the left rear side of my tongue . He examined my mouth but saw nothing to cause it. He referred me to a dental gum specialist who also saw nothing. The initial dentist removed the crown in early 2011 but the pain persisted. The tongue pain may have gotten worse. In the last month, he referred me to a dental specialist: an oral surgeon who saw nothing, even after a sort of CT scan . He suggested extraction of the wisdom tooth which was done a couple of weeks ago. The tongue pain (rear, far left) is much worse, especially when I chew, even though I keep the food as far away on the right as possible. My speech is impaired. Suggestions?
