Did you ever get an answer to your question?
I have the same problem. I had a gum infection that was somewhat painful when I ate on that side of my mouth, it has gone away after a couple days, but for the past 4 there has been a large lump on my gums, above my teeth, where the infection was.
I have the same problem. I had a tooth break while chewing ice. I took antibotics for it that I got from the dentist. I just wanted the tooth pulled. Now I have this huge lump where the tooth is and it doesn't hurt but its hard and I can feel pressure when I touch it. I am freaking out I don't know what it is.
infections in the teeth can sometimes travel down the root into your gums, sometimes the infection can leave a cyst behind, that is prolly the lump your feeling. the dentist usually wont treat it unless your in pain in the area. dont fix anything that not broken ...right?....
