Dentistry/Sensitivity to hot/cold


Hello - I had a filling replaced in one of my lower molars about 1.5 months ago.  Recently, I have been having a lot of sensitivity to hot and cold on that tooth.  I get the pain when I drink something.  However, I am able to chew gum with no problem and I do not get any sensitivity.  I have tried sensitive toothpaste but doesn't seem to help.  Does this seem normal or does it seem more on the lines of a root canal?  I do have an appt scheduled with my dentist but I cannot get in for 3 weeks due to my work schedule and being out of town.  Thank you.

Dear Karisa,
the sensitivity you describe to temperature changes indicates that the nerve in the tooth is irritated following the dental procedure. This is not uncommon , it generally goes away after a few weeks. You may find that by the time you get to see your dentist it has disappeared.
Hope this helps a bit, all the best,
Dr. Moss
