Hello, In January, I had root canal treatment on a premolar (number 25?). When I went back to have the crown fitted, my dentist decided she needed to do a root canal treatment on the adjacent molar (number 26), which had caused the problem in the first place (cavity spreading from that molar to the premolar). As I live abroad, and could only go back to have the crown fitted at the beginning of March, she put a heavy-duty temporary dressing on. Unfortunately, I was unable to go back in March.

Hi, I am very happy to see your long and elaborated dental history. Swelling and mobility in the tooth appeared due to the acute exacerbation of chronic infection in the tooth. Once dentist puncture the abscess and put you on antibiotic that's why you got the relief. About swimming there is no contraindication but the precaution you have to take is get your treatment finished as soon as possible. So that such periapical infection will not occur again. Thanks,
