hi there i had a tooth extracted just over 3 years ago now and have been back to the dentist many many times since then due to a big lump above extraction site plus keep getting abscesses , have burning and sting to right side of tongue, he always says it is caused by smoking or come back in 3 months but no other treatment now i have a new dentist and i demanded a x-ray, she states that i have a infection in the bone and that only surgery will solve it now, would this be what is causing the lump? how much damage will have been done as it has gone on for so long what will surgery do?
