Desperate: That’s me! I have a front left tooth which has previously had a root canal and a crown. Over the past year or so the crown has had to be re-cemented due to loosening up. Now it seems I have a root fracture, an infection which has left me with a constant lump at the top of the gum and again the crown is loose. My dentist recommends minor surgery to remove and replace a part of root which he hopes will then hold a crown, I am on tender hooks and am dreading the prospect of this not working as the thought of having a front tooth removed (although I have dentures to the sides) feels me with dread! Any suggestions? many thanks.
