Hi, Thanks for asking the query, After a successful root canal treatment the canals are removed and the tooth is completely devitalized, so there are no chances of pain. There are chances of pain radiating from the infected tooth to the cheek, ear and neck, I would suggest you to get an x-ray done of the affected tooth. Also look wisdom tooth on the same side if crooked, impacted or crowded can lead to pan in the cheeks. Another cause is allergic reactions, inflammation of the lymph nodes, any blunt trauma to the face, inflammation of parotid gland, growth such as tumors cyst can also cause such type of symptoms. I would suggest you to get a complete clinical evaluation by the Dentist to confirm the cause and plan appropriate treatment, if the tooth is reinfected you have to go for reject of the tooth. You continue with the course of antibiotics and analgesics and maintain a good oral hygiene. Hope this helps out. Regards.
