Dental Health and Root Canals
In the past, if you had a tooth with a diseased nerve, you would have probably lost that tooth. Today, with a special dental procedure called root canal treatment, your tooth can be saved. Root canals are relatively simple procedures, with little or no discomfort, involving one to three office visits. The best news is having a root canal when necessary can save your tooth and your smile!
What is the purpose of a root canal?
Root canal therapy is needed when the nerve of a tooth is inflamed or infected. The most common reasons for this are tooth decay, deep/multiple restorations or a fracture that exposes the nerve of a tooth to bacteria. In order to save the tooth, the pulp (living tissue inside the tooth)is removed and the space is cleaned, shaped and sealed. A tooth's nerve is not vitally important to a tooth's health and function after the tooth has emerged through the gums. The nerve's 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 is detrimental to your overall health as well. Without the proper treatment, your tooth may have to be removed.
What are the signs that a root canal is needed?
Teeth that require root canal therapy are not always painful. However, signs you may need a root canal include a severe toothache, pain upon chewing or application of pressure, prolonged sensitivity or pain to hot and cold temperatures, a dark discoloration of the tooth, and swelling and tenderness in the nearby gums. If you experience any of these symptoms, contact your doctor.
What happens during a root canal?
Root canal treatment involves one to three visits. During treatment, your general dentist or endodontist (a dentist who specializes in problems with the nerves of the teeth) removes the infected tissue. Next, the tissue will be removed and the interior of the tooth will be cleaned and sealed. Finally, the tooth is filled with a dental composite. If your tooth had extensive decay, your doctor may suggest placing a crown to strengthen and protect the tooth from breaking. As long as you continue to care for your teeth and gums with regular brushing, flossing, and checkups, your restored tooth can last a lifetime.
