Root Canals

3 year old root canal - very painful



Approx. three years ago I had a root canal done. This past weekend my tooth really started to bother me, it is extremely sore when drinking hot liquids.


Thermal sensitivity is not a typical symptom of previously treated root canals developing problems.  However, this reaction to hot liquids could indicate that there may be a problem with another tooth in the area. 

I would recommend that you see your local dentist or endodontist for an evaluation.
