I had a root canal treatment. The procedure itself wasn’t too bad and everything seemed fine until a few days ago. Now all of a sudden my tooth is sensitive to cold. I can’t figure out why. Do you have an idea?

Brooke,

If you’ve had a tooth canal and then the tooth becomes sensitive to cold, it means there was a hidden canal that didn’t get cleaned out and needs to be re-treated.  Fortunately, most dentists charge for root canal treatment by the tooth, so there would not be an additional fee for the re-treatment.  If, however, your dentist treats by the canal, there would be an additional fee.

These canals can be tricky and it is not unusual for the best dentists to miss one.  If it is a difficult canal, your dentist may decide to send you to a root canal specialist.
