What could cause a crowned tooth with a root canal from 2 years ago to suddenly become sensitive to sweets?

Question

Joseph H. Hidalgo, DDS · Answer

Most likely the sweet sensitivity is coming from an adjacent tooth. Root canal treated teeth do not have the ability to get sweet sensitive. Sounds like a cavity. See your dentist before it worsens.

Leonard Tau, DMD · Answer

This unfortunately can't be possible , it has to be an adjacent tooth.  I would seek care from a dentist in your area. Sounds like you may have a cavity in a tooth near where the root canal was done .

HI:This is not normal.  It’s best to have a dentist evaluate the tooth and take an X-ray to see if there is a decay on the teeth adjacent to the root canal tooth.Best,Dr. Maddahi
