Root Canals

Sweet sensitivity and root canals



After a root canal, I am still sensitive to sweet foods in the area where the root canal was done. What might be the possible causes? Might it be some problem with the root canal? Or might the cause more likely be a periodontal pocket -- or something else?


Sensitivity to sweets should not be coming from a tooth that has been root canal treated. Often sensitivity to sweets is due to decay (a cavity) in a tooth that has not had root canal treatment. I would recommend an evaluation by your dentist.
