I had root canal on a tooth a few months ago and all has been well until a few days ago. I flossed around the tooth quite vigorously. The next day the gums were a little swollen and the tooth hurt slightly. Since then the tooth has continued to feel heavy with the same sensation in the surrounding teeth and gums. The pain is worse at night and i ve taken advil which helps for many hours until the next night. There is no bleeding and no discharge from the gums.
Hello and welcome to Chat Doctor, Your tooth is root canal treated so cannot suspect any problem with the tooth. Vigorous flossing must have injured your gums leading to gingivitis, that is inflammation of gums which causes redness and swelling. You can have tablet metro along with analgesic 3 to 5 days. Mouth rinsing with lukewarm saline water or antiseptic mouthwash helps in quick healing and gives soothing effect, apply gum paint over the gums after food. After 3 days if pain persists visit a dentist and check for any broken filling or adjacent infected tooth. Take care.
