Hey all, so I posted the other day worried because I have this lump on my gum like it's rock hard but no pain? I've been to dentist and she said there's nothing abnormal there it's a extra bone in your mouth? I thought the most likely reason would be my wisdom tooth so now I'm wondering how you can just grow an extra bone unless I've had it years? I really wouldn't know it's that far back. Anyway I'm not worrying anymore il accept that prognosis. I've just never heard of it before! I don't mind dentists really I ended up having a filling done too pfft lol. Any advice on this bone?
