Extractions
Dental Health and Root Canals
When it is determined that a tooth needs to be removed, your dentist may extract the tooth during a regular checkup or may schedule another visit for this procedure. The root of each tooth is encased within your jawbone in a “tooth socket,” and your tooth is held in that socket by a ligament. In order to extract a tooth, your dentist must expand the socket and separate the tooth from the ligament holding it in place. While this procedure is typically very quick, it is important to share with your doctor any concerns or preferences for sedation.
Once a tooth has been removed, neighboring teeth may shift, causing problems with chewing or with your jaw joint function. To avoid these complications, your dentist may recommend that you replace the extracted tooth.
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.
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 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.
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 affected tissue. Next, 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 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.
