Hi! I am 29 yrs old. Just had extraction approximately three weeks ago of canine root canalled tooth. Now, I am very worried because there is a hard white lump growing in the middle of the gum hole (site where tooth was extracted). This appeared a week after tooth extraction, i thought this was just normal, but I noticed that it's growing bigger. It doesn't hurt and the wound surrounding the white lump is healing well. i was just wondering if any of you have experienced the same thing coz I am a bit of a hypochondriac and I am freaking out...

Thanks!
