Endodontics is a specialized branch of dentistry focused on treating the dental pulp and tissues surrounding a tooth's roots. Central to endodontic services is root canal therapy, which is crucial for saving an infected or severely decayed tooth.

A root canal involves removing the infected or damaged pulp from inside the tooth. The pulp contains nerves and blood vessels that can become inflamed or infected due to deep decay, cracks, fractures, or repeated dental procedures. During a root canal, an endodontist or dentist will carefully remove the compromised pulp, clean and disinfect the tooth's inner chambers, and then fill and seal these spaces. Finally, the tooth is restored with a crown or filling to protect and restore its function.

Root canal therapy is renowned for eliminating dental pain and preserving the natural tooth. The advantages of keeping the natural tooth include efficient chewing, regular biting force and sensation, natural appearance, and protection of other teeth from excessive wear or strain.

Endodontics also includes other procedures such as treating dental traumas involving displaced or knocked-out teeth, performing endodontic surgery such as apicoectomy (removal of the tip of the root), and treating cracked teeth. These procedures aim to save the tooth and maintain its functionality.

Endodontic treatment patients often report immediate relief from prior pain and discomfort. Modern techniques and anesthetics make most procedures manageable and cause minimal discomfort. Endodontic therapy has a high success rate following treatment, and many root canal-treated teeth last as long as natural teeth. Regular dental checkups and proper oral hygiene are crucial for the longevity of the treated tooth.

Overall, endodontics plays a vital role in dental health by preserving natural teeth and preventing the spread of infection, thereby improving oral health and overall well-being.
