 Endodontically treated teeth are prone to extraction mainly due to non-restorable carious destruction, other times due to the improper fit of the crown margins that encircles the tooth which lead to the ingress of bacteria, and to a lesser extent to endodontic-related reasons such as endodontic failure, vertical root fracture, or perforation (procedural error).An infected tooth may endanger other parts of the body.People with special vulnerabilities, such as a recent prosthetic joint replacement, an unrepaired congenital heart defect, or immunocompromisation, may need to take antibiotics to protect from infection spreading during dental procedures.
