Hello doctor,

I have pain two weeks after root canal treatment.



Welcome to

I went through your query and the attached x-ray (attachment removed to protect patient identity). Kindly let me know how long you have been facing pain post root canal. Was it continuous after the procedure did, or it started recently?

The x-ray does not show the distal root end (second root end of the root canal treated tooth). Only the mesial (front) root end is visible. If the pain continues post root canal procedure, then as per the x-ray. In the front root (mesial root), the gutta-percha is extended beyond the root end that might be the reason for pain whenever it is chewed. Do not get a crown unless the issue is resolved.

Another possibility is if the fillings done on the tooth post root canal has a highpoint. The highpoint will always apply extra pressure and hence the pain. So kindly let me know, is the pain continuous, or it hurts whenever you chew? Once I received the information from your end, I would assist immediately and help you in every possible way.

For now, take tablet Ibuprofen (SOS). Do warm saline gargles two to three times a day. Avoid hard food on the root canal treated side as much as possible.

Thank you doctor,

I took two Motrin. My father-in-law is a dentist. He is the one who performed the procedure. I originally had terrible shooting pain with hot and cold substances. Now it just feels like an uncomfortable pain, not shooting nerve pain but like salt on a wound. I tried eating bananas, and it just feels very uncomfortable, like I am pushing in the filling. He did not put a crown because he said it was not needed on how he performed it. I have been like this now for almost 2.5 weeks, and my right lymph nodes developed pain about two days ago right underneath the same side of the tooth. I had one of the residents here to check me out, and they said it is like mild inflammation but nothing major. The gums around that back tooth are red, and it looks like I used a red liner around it, and the rest of the gum is white. It feels uncomfortable, and then I feel like the back tooth's pain radiates up to the front teeth. Does the filling look normal on the x-ray?



Welcome back to

I understood your current situation. It is great that your father-in-law did the procedure. I would request you to visit back to him and get an occlusal grinding. The extra fillings on the tooth bring out the feeling of an uncomfortable chewing experience. According to me, once the extra fillings on the tooth are ground, the tooth should be fine.

If you still feel the same pain even after grinding, you might need a reroot canal to keep the gutta-percha length within or 2 mm short of the root apex. Kindly get the grinding done first and let me know. Until then, take the tablet Motrin (SOS).
