Temp filling after root canal damaged? have seen dentist. crown scheduled later this week. is there a great risk for another infection before?

Antibiotics?: Ask your dentist about the use of prophlactic antibiotics, if needed..

Should be OK: If u have temp filling for a root canal procedure that is scheduled in a few days, your dentist can prescribe prophylactic antibiotic now to provide needed protection for the duration. If you are unable to get the meds before the scheduled date, call their office if you start feeling any pain or swelling in the area.

Temporary filling: It is not uncommon for a temp filling in a tooth that had a root canal to wear down or chip away, especially if some time has elapsed between the root canal and getting a crown. If not too much time has elapsed, and the root canal opening is still sealed, re-infection should not be a problem. Your dentist should check to make sure there is no problem before starting the crown.

Probably Not: The purpose of the temporary filling after root canal treatment is to prevent the influx of bacteria from your mouth. If you damaged the temporary but the dentist checked it and did not feel it necessary to immediately replace it you probably didn't cause any damage. Replace the temporary with the crown anytime after the initial inflammation passes but not longer than 30 days. See your DDS.

You should be fine: Risk of additional infection in such a short time is virtual nil.

No worries: If the root canal is complete, your main concern should be: do not eat on this tooth as to avoid tooth breakage. See your dentist for a final crown restoration. Good luck.

Timing: Important that final restoration be placed ASAP to seal the root canal treatment. If you saw Dentist before temporary broke, call Dentist immediately to report compromised seal and to see if Dentist wants to see you. If Dentist saw the broken temporary and has deemed it still a successful seal, don't worry.
