This past thursday morning I had 3 silver filling replaced on upper left molars...friday morning noticed cheek was a swolen and sore . The soreness is normal for me after having some fillings, but I have never had any swelling...they did need to use a significant number of injections to numb the teeth and 2 of the injections were extrememly painful. Have called the dentist this morning but no return phone call yet...swelling is still there, though it seems to have moved lower? Normal or not?????
