6 days ago I had my top and bottom wisdom teeth out on the left side because of they were causing problems with the teeth in front of them. A couple days afterwards I noticed there was a white film on the gums and teeth on the left side of my mouth and the gums are a real pale pink. The reason I am concerned is two years ago I had a filling that was to close to the root and I got an infection and when this happened the gums in that area also had a white film on them. I have never had this issue before with the white film on the gums.
Is this normal for a wisdom tooth extraction site or should I contact my dentist?
Also it normal to be pain free until you eat something?
