Root Canals Chicago
Root canal therapy restores and saves an average of 17 million teeth each year. Keep your tooth and stop the pain — sounds better than a tooth extraction, right?
What Exactly Is a Root Canal?
A root canal is a dental procedure that is used to remove diseased pulp tissue from the interior of a tooth. The narrow channels beneath the pulp chamber in the inner part of the tooth are hollowed out and cleaned, and the roots are filed with flexible nickel titanium files.
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, or a large restoration — 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.
Root Canal Signs
Certain signs may indicate that you have a diseased tooth or infected nerve and therefore may need a root canal. These signs include:
- Minimal to severe pain.
- Tooth discoloration.
- Swelling and irritation in the surrounding gum tissue.
- Signs of infection visible on a radiograph.
Dentists typically recommend a root canal in such situations to save the affected tooth and preserve its functionality. In some cases, the patient may not have any noticeable symptoms; however, your dentist may recommend a root canal due to the depth of the decay to properly restore the tooth.
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.
