Introduction

Endodontics is a specialized branch of dentistry focusing on the diagnosis, prevention, and treatment of diseases affecting the dental pulp and the tissues surrounding the root of a tooth. The dental pulp—often called the “nerve” of the tooth—is a soft tissue containing blood vessels, nerves, and connective tissue that nourishes the tooth and is essential for its vitality.

When this vital tissue becomes inflamed or infected due to factors such as deep decay, trauma, or cracks in the tooth, an endodontic procedure is often required to save the tooth. The most common endodontic treatment is root canal therapy, which involves removing the diseased or damaged pulp, cleaning and disinfecting the canal system, and sealing it to prevent reinfection.

Endodontics has transformed dental care by enabling the preservation of natural teeth that might otherwise require extraction. By maintaining the natural dentition, patients retain optimal oral function, aesthetics, and jawbone health.

This comprehensive guide explores the causes and risk factors associated with endodontic conditions, common symptoms, diagnostic approaches, treatment options, preventive measures, possible complications, and living with treated teeth.

Dental Caries (Tooth Decay): The most common cause of pulp inflammation and infection is untreated deep cavities, allowing bacteria to penetrate into the pulp chamber.

Dental Trauma: Physical injury from accidents, sports, or habits such as grinding can cause pulp tissue damage, bleeding, or necrosis.

Cracked or Fractured Teeth: Cracks allow bacteria direct access to the pulp, leading to inflammation or infection.

Repeated Dental Procedures: Multiple fillings or restorations can irritate the pulp and compromise tooth vitality.
