Endodontics is a specialized branch of dentistry focused on diagnosing and treating diseases of the dental pulp and root tissues. The most common procedure in endodontics is root canal treatment, which saves infected or damaged teeth by removing the pulp, cleaning the canals, and sealing them to prevent reinfection. Endodontic therapy helps preserve natural teeth, preventing the need for extractions and maintaining oral function. Advanced techniques, including digital imaging and rotary instruments, make treatments more efficient and comfortable. By relieving pain and restoring dental health, endodontics plays a crucial role in maintaining a healthy, functional, and long-lasting smile.
