I have a tooth that I was told needs to be pulled.  I havent done so yet and I had a toothache in it for a day.  The following day I found a large bump on my gums right under the tooth.  It does not cause any pain but I have had it for nearly a month and it is not going away.   You can actually see tge lump on the lower oart of my cheek it sticks out that far.  The tooth has very little pain either however in looking at it it is clear it needs removed.  What could this bump be and will it go away on its own?
Thanks for your query, I have gone through your query. The pain and the lump over the gums can be because of the infection in the tooth and gums. Consult a dental surgeon and get the tooth removed. Meanwhile you can take a course of antibiotics like amoxicillin and metronidazole combination(if you are not allergic). Then consult your dental surgeon or oral physician and get the tooth removed as early as possible. I hope my answer will help you, take care.
