About Root Canals
Root Canal Therapy
What Exactly Is a Root Canal?
A tooth is made up of three main components: a hard protective shell referred to as enamel, a softer and sensitive middle layer referred to as dentin and a soft tissue inner layer referred to as dental pulp. Dental pulp is composed of nerve tissue, lymph tissue and blood vessels, and is considered to be the vital part of a tooth. If dental pulp is sufficiently traumatized – whether by exposure to oral bacteria via deep dental caries, a fracture in the tooth that enters the pulp or a forceful blow to the face – the tooth begins to die and root canal therapy is often required in order to prevent or eliminate infection and prevent tooth loss.
A root canal procedure involves tooth disinfection and the removal of all debris (nerve tissue, lymph tissue, blood tissue, bacteria and infection) from the coronal pulp chamber and its associated canals. Once an affected tooth’s canals are sufficiently cleansed and shaped, they are filled with materials designed to prevent pain and infection from recurring.

Why Are the Associated Toothaches So Painful?
Nerve fibers, blood, and lymph tissues are housed in the root canals. Located inside each tooth is a pulp chamber that funnels into those root canals.
A tooth can become inflamed or infected for several reasons, including severe tooth decay or a crack or chip in the tooth. Failing restorations such as dental fillings and dental crowns can foster bacterial leakage into the dental pulp. Once infected, the dental pulp begins to die and the body’s inflammatory responses set it. The combination of infection and inflammation can cause significant pain. The end result is a toothache.
In cases where tooth extraction is the only solution, the missing tooth may be replaced with a dental implant or dental bridge to maintain functionality. By replacing the missing tooth, a proper bite is maintained and the surrounding teeth are prevented from shifting. Because a severe infection can be very dangerous, it is important to receive a professional evaluation by a dentist who can look deeper into the cause of a toothache. If an infection spreads beyond the jaw to the head and neck, then more extensive medical treatment, including hospitalization, may be required.
