If course it's the weekend now when this happens.... I had a root canal on Monday and today(Sat AM) when I checked the tooth, some of the cotton was coming out of the tooth. Agh!! I called the endodontist and they said to try and seal it again myself w/ a tooth filler from the drug store, until I can get in on Monday. I have never heard of this, but will look for it today. I will rinse constantly w/ Listerine and hydrogen peroxide to try and keep it clean. I'm concerned about contamination. Has anyone ever had this happen and what did you do?

Thanks!
