Will losing temporary filling after root canal ok?

No: It is normal to wear out some of the temporary filling. However, it is not good to have the temporary filling completely out. Once the inside of the tooth is exposed to contaminants like saliva, bacteria and food, root canal will become contaminated and eventually leak. Go back to your dentist right the way to have it checked.

No: root canal is a process of preserving your tooth. if your temp falls, you need to see the dentist cause bacteria will go inside the tooth and cause infection. The hole has to be covered to avoid re-infection.

It is not OK: Over time, bacteria will leak into the root canal sealer cement. If this happens you may need to redo the root canal therapy. See your dentist ASAP.
