Endodontics is a branch of dentistry focused on diagnosing and treating issues related to the dental pulp and root tissues. The dental pulp, located inside the tooth, contains nerves, blood vessels, and connective tissues. Endodontic treatments primarily involve root canal therapy, where the pulp is removed, and the root canals are cleaned, disinfected, and sealed. This procedure alleviates pain, saves the tooth from extraction, and prevents further infection. Endodontists, who specialize in this field, also handle cases of tooth trauma and complex root canal systems. By preserving natural teeth, endodontic treatments contribute to overall oral health and function, allowing patients to maintain their teeth for a lifetime.
