Question
HI,
Is it imperative to remove ALL temp filling and cotton in order to place a permanent filling post root canal?
Does leaving cotton behind cause bacteria?

Answer
Hello Lisa,

I would never leave cotton in a tooth under any circumstances. I use it only to medicate a tooth.  On occasion I might leave some of a medicated filling what we term IRM under a restoration but that is on a vital tooth to protect it from thermal insult.  So to answer your question I think all cotton should be removed before a final restoration is placed.  Thanks for a good question.  Leaving the cotton behind doesn't cause bacteria but if there is bacteria present it might make a good place for it to grow.



Yes Lisa remove all temporary filling material
