It is the special branch of dentistry that deals with study of treatment, diseases of the tooth root, dental pulp and surrounding tissue.
Endodontic treatment is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, faulty crowns, or a crack or chip in the tooth. If pulp inflammation or infection is left untreated, it can result in an abscess.
Endodontists perform a variety of procedures including endodontic therapy (commonly known as "Root Canal Therapy"), Endodontic Re-treatment, surgeries, cracked teeth & treating dental trauma. To understand a root canal procedure, it helps to know about the anatomy of the tooth. Under the white enamel and a hard layer called the dentin, is a soft tissue known as the pulp. It contains blood vessels, nerves and connective tissue that helps in the root growth of your tooth during development. When fully developed, the tooth can survive without the pulp as the tooth is nourished by the surrounding tissue.
During a root canal treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, and then filled and sealed with a rubber-like material called gutta-percha. Afterwards, the tooth is filled for protection and then crowned. After restoration, will continue to function normally.
Contrary to jokes about the matter, modern root canal treatment is very similar to having a routine filling and usually can be completed in one or two appointments, depending on the condition of your tooth and your personal circumstances. You can expect a comfortable experience during and after your appointment.
Saving the natural tooth with a root canal treatment has many advantages:
Endodontic treatment helps you maintain your natural smile and limits the need for ongoing dental work. With proper care, most teeth that have had a root canal treatment can last as long as other natural teeth and often for a lifetime.
