I had a tooth surgery extraction by g.a last week friday and I still have pain in my whole mouth. I have seen that my (cheek) inside my mouth is red and there is white stuff which looks like pus. In the meantime all my teeth on the side where the extraction was done are aching. I am surprised though where the extraction took place it is healing well, though the stitches are still there and this area is only itchy but no pain. I have finished the pain killers that the doctor gave me, am still rinsing my mouth with salt water and some mouth wash. Is it normal that the inside cheek developed an infection? And how is this possible. Should I go back to see the doctor! Or is this part of the healing process???
