Hi, Thanks for asking the query, Tooth pain along with swelling indicates infection of the tooth that had spread to the periapical tissues leading to formation of abscess. After successful root canal treatment the tooth is completely devitalized, so there are no chances of pain and infection. I would suggest you to visit to the concerned Dentist take an x-ray of the tooth, depending upon which the treatment will be extraction or reject. Start with tab Amoxiclav and tab Aerosol twice for three days. Take lukewarm saline gargles 3-4 times and antiseptic mouthwash gargles twice daily. Hope this helps out. Regards....
