Endodontics, a crucial branch of dentistry, focuses on diagnosing and treating diseases affecting the dental pulp and surrounding tissues. This specialized field primarily deals with root canal therapy, an essential procedure to save teeth damaged by decay or trauma. Through precise techniques, endodontists alleviate pain and restore oral functionality by removing infected pulp, cleaning the canals, and sealing them to prevent reinfection. Advances in technology, such as rotary instrumentation and cone-beam computed tomography (CBCT), have significantly enhanced treatment outcomes. Endodontics not only preserves natural teeth but also contributes to overall oral health by preventing complications like abscesses or tooth loss. Prioritizing timely endodontic care ensures a healthier smile and improved quality of life.
