Does anyone have any experience of a tooth infection spreading to the bone and what treatment they received? My dentist show me my X ray and explained that it showed I had an infection in the bone all around the painful tooth. She put me on antibiotics for 7 days and is referring me to maxfax to have the tooth removed. It has to come out because I am have low immunity now due to DMARDS. I have decided to miss my mtx this week as a precaution and because everywhere is shut for the weekend so i cant get any medical advice. The pharmacist said she didn't know what I should do. Anyone got any ideas? Jane.
