In the past, if you had a tooth with a diseased nerve, you would probably lose that tooth. Today, with a special dental procedure called root canal treatment, your tooth can be saved.
Root canal treatment is a relatively simple procedure that involves one to three office visits. Best of all, having a root canal when necessary can easily save your tooth and your smile!
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 occur. 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.
Teeth that require root canal therapy are not always painful. However, signs you may need a root canal include severe toothache, pain upon chewing or application of pressure, prolonged sensitivity or pain in response 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 immediately.
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) will remove the affected tissue. Next, the interior of the tooth will be cleaned and sealed. Finally, the tooth will be filled with a dental composite. If your tooth has extensive decay, your doctor may suggest placing a crown to strengthen and protect it from breakage. 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.
