I have had a lump under my gum on bottom jaw since before Christmas. Seen dentist twice and second time she said she would refer me as it hadn't gone with antibiotics, although she had done x-rays and nothing on those. Last appointment was June and I havent heard anything. Should I go to doctors to see if they can get things moving? Back to dentist? Feeling it today and I believe it has got bigger although it is hard to measure. Mostly concerned as my brother had oral cancer (had to have an operation but now in recovery) and it was the family history that made the dentist want to refer me. Not sure when or how to chase...
