Hi, I am having problems with a upper tooth that I had removed 4 weeks ago. It all started when my tooth was damaged through a basic root canal treatment. I was referred to a specialist and 9 months later I was told it would have to be extracted, meanwhile I had faced a number of infections and 2 courses of antibiotics. At the time of the extraction the root was infected. After the extraction, dissolvable stitches were put in place as I was flying overseas and the sinus was exposed. Now, 4 weeks later, my dossolvable stitches are still in place and seem to be surrounded by a white gooey substance. When I touch with a Q tip the white substance moves about, attached to the stitches and is adding to some slight irritation of that area. Is this normal? Thanks!
