Hi, I have a 6 month old crown on my left upper front tooth. 2 weeks ago I developed a rapid swelling. I went to see my dentist and he said that I had a periapical abcess and would need a root canal, but he cant do it for 6 weeks. The swelling was causing such discomfort I pierced the swelling with a 23 G syringe needle and white pus drained out. Now the swelling is back but is very hard and when I tried to drain it again nothing came out. Could this be a malignant tumor? I am really worried as the swelling is now a hard, non-drainable lump. I have been on Amoxicillin 500 mg po since 6/30/11. Any advise or answers to what this might be. Thanks for your response.
