I'm having a root canal retreatment done, second appointment is on mon. top of temp. filling fell out tonight, can i wait until next app.?.

Call: It's always best to call the dentist (or physician) actually treating you for advice. Having said that, until then, avoid eating on that tooth, especially hard foods. Also keep that area especially clean so food debris does not collect in the hole.

Nothing to worry: Place a temporary filling material where the filling is missing. You can buy temporary filling material called Dent Temp over the counter in any pharmacy. Do not miss your Monday appointment to complete your root canal therapy. Have a nice weekend.

Possibly: if only a part of the temporary came out, there is still a seal and no problem. If you taste medication, then call your dentist and get it replaced.

Probably but...: You can probably wait, but I would call the office since they are aware of the treatment that was performed.

Seal: To be successful root canal has to be sealed at both ends, top & bottom. If part of sealing material comes out root canal can become recontaminated. Call the treating Dentist or specialist Endodontist and ask their advice.
