Gum biopsy

[rainrainsun]

Any dentists about? I had root canal work with a crown approx 18 months ago.

A while before then I noticed white patches along the that part of the gum which dentist couldn't identify but thought might be some sort of reaction to a toothpaste (although I never use the same one so unlikely), or trauma caused by teeth grinding. The grinding caused the need for the root canal.

Anyway i have noticed over the last few months a particular white patch where the crowned tooth and gum meet which has developed into a raised cluster of white cells.

I have been referred for a biopsy and you can imagine what's whirling round my mind. The max-face dentist doesn't think it's sinister but I am now really worried.

Trying to keep things in perspective there has been a lot of movement in that tooth and am wondering if it's some kind of trauma caused by a failed root canal. The dentist said it was now just routine to refer prior to taking any action of remedial tooth work or just removing it and wasn't overly concerned

I know it's stupid to ask for a medical diagnosis via DR Mumsnet but would sincerely appreciate any thoughts or if anyone has experience of this.
