Root Canal Therapy
If your tooth’s nerve chamber becomes infected by decay, or damaged by trauma, a root canal treatment is often the only way to save your tooth. Inside the hard outer shell of each tooth is a specialized area called the pulp or nerve chamber that contains a system of blood vessels, lymph vessels and nerves. This system provides nourishment for the cells within the tooth and enters from the bone through the root canals.
Deep tooth decay or trauma can cause damage or infection of the tooth pulp. In a root canal or endodontic procedure, the dentist removes the damaged or infected tissues and replaces it with a filler material that helps maintain the remaining tooth structure.
After a tooth has had root canal therapy, it becomes dry and brittle due to the lack of nourishment, making the tooth prone to fracture. A crown is usually recommended to restore the tooth properly.
Some indications for root canal therapy may be:
+ Spontaneous pain or throbbing while biting
+ Sensitivity to hot and cold foods and drinks
+ Severe decay or an injury that creates an abscess (infection) in the bone
