at the back of my mouth, I have what looks like an ulcer, it's like a small white growth, been there for quite a while but as it's hardly visible and caused no discomfort; I've ignored it. Past couple of days, the left side of my mouth has felt swollen and today a sort of small black lump has appeared on the side of my mouth (on the inside). My mum said it was a gum boil, I've looked it up online but I'm not so sure that it is.
Just wondering if anyone can shed any light on this? dunno whether to book an appointment at the dentists or just wait and see if it goes
