A root canal is a dental procedure used to remove diseased pulp tissue from inside a tooth. The narrow canals below the pulp chamber on the inside of the tooth are hollowed out and cleaned, and the roots are filed with flexible nickel-titanium files. Root canal therapy restores and saves an average of 17 million teeth each year. Keep Your Tooth And Stop The Pain - Sounds Better Than A Tooth Extraction, Right? 8595151961
