Q. Dear Dr Moore, I had two lower back teeth removed with a bone graft on both. My dentist gave me antibiotics but as soon as they were finished I had the most awful infection, my face was badly swollen and I was in terrible pain until the end of the second round of antibiotics. Is it possible for you to tell me if I would be at higher risk of infection when (and if) I go ahead with the two implants. I am terrified of getting more infection. I am 60 years old. Many thanks. PS. both extracted teeth were quite badly diseased and decayed.
