Pain on exposure to cold food after getting root canal treatment done. What should be done now?

Hello, I ll get right to it... Went to the dentist for first time in 4 years. Got a good cleaning and replaced 2 old fillings with new ones ( tooth colored now, old were silver/metal). The fillings were on my back 2 left teeth . He noticed some decay in next to last tooth. 1 month later, pain starts up from eating/biting/ cold sensitive. I go back to my dentist and schedules a root canal on next to last tooth. Root canal done, three days later I start getting pain from cold stuff again. Could the endontist have missed some of the pulp? (There was no infection, just inflamed) now, when I drink just water on the left side, the pain starts mild increases to BAD then decreases... All within 30-45 seconds. Getting a little worried, trying to stay calm about this. We schedule a re-eval with endontist for sometime soon... Any words of wisdom or comfort are welcome. My original visit over a month ago gave me a boost to want to go to the dentist more often and take better care... But this whole situation is really bumming me out. Any info or suggestions?

Hello and thank you for your question.

The pain could be related to remaining infection in the tooth you have had done, or the tooth next to it was the one needing the root canal. The level of pain you are experiencing means you have a dying nerve and are suffering from irreversible pulpitis. Best thing to do is to go to an endodontist and have a pulp vitality test performed on all of your teeth in that area to determine which tooth is the source of pain.

Best Wishes,

After root canal treatment there is totally end of sensation rather it may be hot or cold .if any type of sensation is present in it then there is chance of missing canals or shorter the working length of the canals. in that type of case may be your adjacent tooth is periodontal y compromised and it have sensitive to cold and you feel pain on treated teeth. So I suggest to you go your endodontic and take a proper treatment.

Welcome to HCM
I would like to tell you that root canal treatment involves complete desensitization of teeth because nerve is completely removed so teeth becomes non-vital.Still if you feel any sensitivity in same teeth then it gives a clear indication that some canal is remaining or RCT is not proper.
I would like you get your all teeth checked by vitality testing. There might be caries in other teeth or some periodontal problem.

Take Care
