I had a spongy green stuff coming out from my root canal treated tooth. Could this be mold?

Hello,

Welcome to icliniq.com.

I have to say this. Your root canal treatment was not completed. The green spongy thing is nothing but discolored cotton pellet used to cover the root openings top of which a temporary filling was done. This is so obvious that the tooth was not given a permanent filling at all. Please check with your dentist again for the X-rays taken before and after the treatment which will allow to find out if the root canals were filled or not.

The reason for the food lodgement is that the temporary filling has dissolved slowly and left-back the big cavity to snug in the food particles. Now, there are a lot of chances for the bugs to retain in the tooth for which you had to undergo a second thorough cleaning of the root canals (most probably without injections). Meanwhile, I advise you to use chlorhexidine mouthwash 0.2 % (without alcohol) 10 ml and rinse with it twice daily for a minute and a week. This will give you an antiseptic effect and remove bad odor.
