Endodontic therapy, commonly known as root canal treatment, is a dental procedure designed to treat infections, injuries, or damage to the dental pulp (the soft tissue inside the tooth) and surrounding tissues. The goal of endodontic therapy is to save a tooth from extraction by removing the infected or inflamed pulp, cleaning and disinfecting the root canal system, and sealing it to prevent further infection. Here’s an overview of the endodontic therapy process:

1. Diagnosis and Evaluation:

• The process begins with a thorough examination by a dentist or endodontist (a dentist specializing in root canal treatment). Symptoms such as toothache, sensitivity to hot or cold, swelling, or gum tenderness may indicate the need for endodontic therapy. X-rays or other imaging tests may be used to assess the extent of damage and determine the best course of treatment.

1. Local Anesthesia:

• Before the procedure begins, local anesthesia is administered to numb the affected tooth and surrounding tissues, ensuring that the patient remains comfortable and pain-free throughout the treatment.

1. Access Opening:

• Once the tooth is numb, the dentist creates a small access opening in the top of the tooth, usually through the biting surface (occlusal) or back of the tooth (lingual/palatal), to gain access to the pulp chamber and root canals.

1. Pulp Removal:

• Using specialized instruments called endodontic files, the dentist carefully removes the infected or inflamed pulp tissue from the pulp chamber and root canals. The root canals are cleaned and shaped to remove any debris, bacteria, or infected tissue.

1. Root Canal Disinfection:

• The root canals are thoroughly irrigated with antimicrobial solutions to disinfect and flush out any remaining bacteria or debris. This helps eliminate infection and reduce the risk of reinfection.

1. Filling and Sealing:

• Once the root canals are cleaned and disinfected, they are filled with a biocompatible material called gutta-percha to replace the removed pulp tissue and seal the canals to prevent bacteria from re-entering. The access opening is then sealed with a temporary or permanent filling.

1. Restoration:

• After the root canal treatment is completed, the tooth may require a permanent restoration such as a dental crown to protect and strengthen the tooth’s structure. The crown restores the tooth’s appearance, function, and integrity, allowing it to withstand normal biting and chewing forces.

1. Follow-Up Care:

• Following endodontic therapy, patients may experience some mild discomfort or sensitivity, which can usually be managed with over-the-counter pain medications. It’s essential to follow any post-operative instructions provided by the dentist and attend any recommended follow-up appointments to ensure proper healing and the long-term success of the treatment.

Endodontic therapy is highly successful in saving teeth that would otherwise need to be extracted due to infection or damage. With advancements in techniques and technology, root canal treatment has become more comfortable, efficient, and predictable, allowing patients to preserve their natural teeth and maintain optimal oral health.
