I had a feeling I had an exposed nerve in my back molar so I went to my dentist (after 3 years without beeing seen). He said I needed deep gum cleaning at the site, we did that, and now it is more painful than before. If I touch an area between my teeth the pain sends me through the roof. I do not want to go back to him just yet, if at all. I just want releif from the pain. It is not constant, but consistent. Any suggestions?
