I have had a filling fall out of a tooth. The cavity had gone into the pulp so I have to wait till December for another office to take out. The gum is not inflamed , however I have been feeling nauseated, headache, my body is shaky, neck pain, ear pain on that side, and no fever. I also have hard small bump on the front bottom of my mouth along a bone, in the bone that comes to a "T" in the front of the mouth under the tongue. It also is sore in the back of my head, in the center, at the nap of my neck, where the indentation is at the top of the cervical spine.
