Hello, Thanks for writing to us, I would like you to know that pain after root canal treatment needs attention of a dentist soon. It could be from reinfection or even from a fracture in the tooth. But as you mentioned here that x-ray does. Not show any signs of fracture so i assume your dentist will be the best who can inform you of the reason. Also I would advise you to take a second opinion from a root canal specialist. Enzoflam alone will not treat the pain, you will have to take antibiotics as well. Over the counter Pain killer which contains ibuprofen will be better in your case. Kindly perform warm saline rinses and apply cold packs on the area. I hope i answered your query. I wish you good health. Thanks Take care.
