<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi i just came from the dentist a few hours ago and was told this lump on the inside right hand side of my lower jaw just a inch from my teeth and was told it was a bone that grew out. can this happen and should i be concerned even tho i was told it was nothing?  <response>: Hi, wow I thought I was the only person to have this! Ive had mine for about 3 whole years and it hadnt started hurting until now. I saw my dentist, who didnt know what it was so made me an appointment at the hospital, who x-rayed it and confirmed it was a bone. It wasnt bothering me, so they said there was no point taking it out, but now about 3 months later it has grown to about twice its original size?! So Im going to the hospital tomorrow for another appointment and I will probably eventually get it removed :S
