What is this thing on my gums? i have had a hard bone like growth on my bottom front tooth it seems to be connected to the broken tooth which is there. there was an abscess a long time ago that burst and left a hole in my gum. now the broken tooth

Hard : Hard to tell sight unseen and without a radiograph, but it sounds like the abcess and broken tooth you left untreated for such a long time has created a substancial amount of bone loss around that tooth. It could be that the root end is poking through the hole in your bone and sticking into your gum tissue. Not a healthy situation. Obviously you understand that you need to go see a dentist to have the tooth extracted. The dentist who extracts the tooth will determine if it is indeed the root end or something else. Please go and be seen as soon as possible to avoid further complications or massive infection.

Without : Without seeing the area, it is very difficult to diagnose. However, it is very impotant that you contact a dentist immediately to have the broken tooth removed and any infection addressed. What may seem like a small area of infection can, does, and will have systemic effects. The growth may be granulation tissue, (a fibrous mass of tissue), portions of broken tooth, or some type of lesion that would be removed at the time of extracion. I would also recommend, a full examination with a full set of radiographs to evaluated the health of the rest of your mouth. You will want to address any issues to prevent any further loss of teeth.

It : It is very hard to be sure what is exactly wrong with out having an x-ray and examining you. But certainly you need to go and see a dentist or and oral surgeon immediately. When teeth abscess they damage the surrounding bone. If you happened to have a torus ( a boney out growth called an exostosis) is it possible that as the blood supply is poor to these outgrowths the bone may have died and your body is not trying to isolate and reject the dead tissue by a process called sequestration. It is just a guess. Please go and get help dr. Neil mcleod dds dentistry that lasts - quality that counts.

Could be many things: See a dentist asap, since you report previous abscess and broken tooth. It can be a life threatening situation. The draining area may have hardened or calcified, it may be of little concern. But without an exam, we can't know.
