question: I am a 22 year-old female and I had a root canal done a week ago. Prior to the root canal I complained of sensitivity and a feeling like a pocket was forming in the gum line on my upper left between my back tooth and my molar. My dentist did a root canal and prescribed clindamyacin for what I assume was an infection (he did not tell me what was really wrong). I went home waiting to return the following week to finish the root canal, but in that time, extreme sensitivity has emerged on the gum line and in between the molar and last tooth in 3 out of 4 of my molars (all aside from the bottom right). I have been brushing gently with a soft brush, using non-alcohol mouth washes, and flossing and the pain and bleeding just seems to be getting worse. I will be going to the dentist today, but I wanted a second opinion as to what could be going on. I had early signs of gingivitis in previous years, but have taken care of my teeth including brushing, flossing occasionally (not every day as I should) and using anti-gingivitis mouth washes. What could have caused the spread of such pain and bleeding in my gums over my molars in such a short time? Could it be related to my root canal?
