-What Is Gutta-Percha?
Gutta-percha is a material used to fill a tooth after a root canal procedure. Gutta-percha, a plastic substance from a Malaysian tree called a percha tree, is used as a permanent filling in root canals. During the root canal procedure, the tooth's damaged area, known as the pulp, is removed, and the tooth's canals are cleaned out and disinfected before being filled and sealed. Gutta-percha is the thermoplastic filling material heated and compressed into the tooth's canal, then sealed with adhesive cement.
