I had a root canal done on #15 approx 10 months ago. For the past couple of weeks this tooth is very sensitive to heat. I have noticed a deep pocket at the gum line that I may have missed with flossing and am now trying to correct with being more careful and using a dental brush to get in there to make sure it's really cleaned out.
Could this be the cause for the senitivity in this tooth that has already had a root canal? It is definitly this tooth. This is the only symptom......Thanks
