Root canal?
If the RCT has been OK for a year, then it is probably fine. The most common cause of your problem is a crack in the tooth. Teeth which have been RCTd are usually quite weak, and a full-encirclement crown is usually required to prevent cracking.


Go seek dental advice ASAP.
Reply:maybe it got reinfected. Dentist time.
Reply:sounds like the tooth needs pulled out


maybe the nerves or same problem you had to start with


see a dentist
Reply:If the Dr. you saw did not put a crown over the tooth there is a good chance that the tooth has been re-infected. Get it checked out because the infection can easily spread to other teeth, and I'm sure you know root canals aren't cheap.
Reply:if you only had a filling in there then the dentist was not finished.a root canal visit is more then 1 the filling is a temp.u have to go back and get it finished
