Root Canals
Understanding Basic Tooth Structure
Teeth are built up around central channels that contain the nerves, blood vessels and connective tissue required to grow the tooth during development. This channel in each tooth is referred to as the pulp. Because the pulp contains the nerves, it is the sensitive part of the tooth and what is removed during a Root Canal. Surrounding the pulp is a hard layer called dentine (the Latin word for TOOTH). The dentine part of the tooth above the gumline is covered by enamel, the hardest substance in the body, whereas the dentine below the gumline, the root, is surrounded by a thin layer called cementum and serves to anchor the tooth to the jaw.
What is the purpose of a root canal?
A tooth's nerve is not vitally important to a tooth's health and function after the tooth has emerged through the gums. Its only function is sensory – to provide the sensation of hot or cold. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth.
When a tooth is cracked or has a deep cavity, bacteria can enter the pulp tissue and germs can cause an infection inside the tooth. If left untreated, an abscess may form. If the infected tissue is not removed, pain and swelling can result. This can not only injure your jawbones, but it is detrimental to your overall health. Without the proper treatment, your tooth may have to be removed.
Why Are Root Canals Performed?
Tooth damage from decay, injury or genetics can lead to an infection in the pulp. Infection in this area filled with nerves and blood vessels can be extremely painful; you may experience pain, swollen gums and sensitivity to hot and cold. When you have symptoms such as these, we may recommend a Root Canal.
What happens during a root canal?
During a Root Canal, the inflamed or infected pulp is removed. Fully developed teeth can survive, remaining naturally cemented in your jaw, without the pulp because the dentine continues to exchange materials with the bloodstream, providing the nourishment it needs. Before the Root Canal is performed, patients are numbed with a local anesthetic. A small hole is then drilled in the crown of the tooth, the pulp is removed and the area is cleaned and filled. Depending on the condition of your tooth, the procedure may take multiple appointments. Patients are not in pain during the procedure because an anesthesia is given; however, you may experience soreness and discomfort after the procedure for a few days. Post Procedure Care Temporary soreness and discomfort are to be expected after the local numbing anesthetic wears off and you may be prescribed medication to help with the pain and antibiotics to treat infection. Follow the instructions carefully on any medications that are prescribed. The discomfort should only last a few days as the area heals. You will schedule another appointment for the final crown to be put on and then your tooth will be fully restored. Post Procedure DO’S and DON’T’S DO wait for the numbness in your mouth to wear off before eating to avoid biting your tongue or cheek. DON’T bite down on the treated tooth until the final crown has been put on and the tooth is fully restored. DO continue with your daily oral hygiene of brushing and flossing. DO call us if you have any questions or are experiencing any unusual pain or discomfort. Crowns look and function like natural teeth and should last as long as a natural tooth would.
