Root canal procedures remove the pulp from a tooth. Even when some tissue is left behind it is not living tissue. Endodontically treated teeth do not have the ability to feel cold sensitivity unless vital pulp tissue remains in an untreated root and this rarely is the case.
If your endodontically treated tooth seems to be sensitive to cold, the most likely cause is an adjacent tooth. A visit to the dentist where he performs an ice challenge will usually demonstrate which tooth is experiencing sensitivity.
That being said, teeth with endodontics still can feel pain due to the presence the periodontal ligament. If the tooth displays either periapical inflammation or infection it can be sensitive to pressure, chewing or percussion. Failing root canals can present as 'toothaches' as well. Cracks in endodontically treated teeth similarly can cause pain in the surrounding periodontal ligaments.

what about heat sensitivity? I had heat sensitivity, pain shot through my jaw when I ate hot things. Just had a root canal done today. Tonight, the heat sensitivity is still there.
The doctor said she worried about #21, but it could still feel cold. #20 (the one we did today), couldn't feel cold at all.
Just wondering if I should call her tomorrow because I need one on the second one as well or if maybe my tooth is just still sensitive.
Dear Jenn,
Non vital teeth without root canal fills can theoretically experience sensitivity to hot, but if you just had a root canal treatment it is unlikely. The reason this is possible is that gases can build up from the deterioration of a necrotic pulp that can expand when exposed to heat. Your root canal treatment removed any necrotic pulp present. Most likely your sensitivity is originating from an adjacent tooth.
I just had a root canal done 6 days ago and I noticed that it is still sensitive to cold. There is lingering shooting pain after drinking ice drinks. Is this normal?
I had a root canal done 15 days ago on tooth #10. I still have pain and nothing works to relieve the pain. My dentist wont fill the tooth because I still have pain. I went to an endodontist for the root canal. What could be the problem? What should I do?
