Dear Mr. Rotar
In January this year I had an apicoectomy on the upper central incisor, in which I have a post and crown. In the gum area  above the apicoectomized tooth a small blister or (bump) appears, which disappears when touched. On the X-ray I had last week on the advice of my dentist  nothing unusual is visible. I would like to know whether it is possible that pus is accumulating again or that the bone in the area of the filling has not yet regenerated enough to fill the defect. I would also like to know how long it usually takes for bone to grow back. I have a check-up in December with the specialist who performed the apicoectomy; would you perhaps advise me to try to get an earlier appointment or is there no need to worry?
Thank you in advance for your answer
Kind regards
Grega
