Yes, they are sensitive to hot and cold, then other times just hurt even when not eating or drinking. Usually one time a day it will get really bad. Iwould presume it would mean that I need a root canal, the problem is the dentist has taken x-rays and does not see any problem. I am not even sure which tooth is hurting. I see the prothodontist this week, which is suppose to be to begin the process for my difinitive obturator. I plan to discuss this with him and hope to get some answers.
