Endodontics, or root canal therapy, is employed when the nerve supply to a tooth has been irreversibly affected by damage or decay. It is a way to prevent or help resolve a dental infection and save a natural tooth from extraction. A root canal is performed when enough healthy root and crown structure is remaining to restore form and function to the involved tooth eventually.
Inside every tooth is either a single central chamber or multiple ones that contain connective tissue, a nerve supply, and blood vessels. These core tissues, known as the dental pulp, help your tooth to grow and mature before it emerges into the mouth. A root canal procedure is required when this dental pulp is irreversibly damaged or has died.
Root canal therapy involves cleaning and shaping each canal and then filling them with unique inert material. Following this, they are sealed to prevent any subsequent infection. Once root canal therapy has been completed, the tooth should be fully restored as recommended.
