I can no longer bear to bite down with my back teeth, discouraging me to eat. From the back the tooth, my gums in the back of my mouth are beginning to grow over my bottom right wisdom tooth (I am 18, and due to have my wisdom teeth cut out; I'm in college and refuse to make time to have them removed). If I even touch this part of my gums slightly, I will feel a painful sensation for several seconds immediately after. The entire region surrounding this tooth is in excruciating pain. What can I do to fix this?
