Endodontics (Root Canals)
Once upon a time, if you had a tooth with a damaged nerve, you’d probably lose that tooth. Inside each tooth is the pulp which provides nutrients and nerves to the tooth. The pulp runs like a thread down through the root. When the pulp is diseased or injured, the pulp tissue dies. If the pulp is not removed your tooth will become infected and you could lose it. After the dentist removes the pulp, the root canal is cleaned and sealed off to protect it. Then your dentist places a crown over the tooth to help make it stronger. Most of the time, a root canal is a relatively simple procedure with little or no discomfort involving one to three visits. Best of all, it can save your tooth and your smile!
What is root canal treatment?
Your dentist uses root canal treatment to find the cause and then treat problems of the tooth’s soft core (the dental pulp). Years ago, teeth with diseased or injured pulps were removed. Today, root canal treatment has given dentists a safe way of saving teeth.
What is the dental pulp?
The pulp is the soft tissue that contains nerves, blood vessels and connective tissue. It lies within the tooth and extends from the crown of the tooth to the tip of the root in the bone of the jaws.
What happens if the pulp gets injured?
An abscessed (infected) tooth caused by tooth decay. When the pulp is diseased or injured and can’t repair itself, it dies. The most common cause of pulp death is a cracked tooth or a deep cavity. Both of these problems can let germs (bacteria) enter the pulp. Germs can cause an infection inside the tooth. Left without treatment, pus builds up at the root tip, in the jawbone, forming a “pus-pocket” called an abscess. An abscess can cause damage to the bone around the teeth.
Why does the pulp need to be removed?
When the infected pulp is not removed, pain and swelling can result. Certain byproducts of the infection can injure your jaw bones. Without treatment, your tooth may have to be removed.
What does treatment involve?
Treatment often involves from one to three visits. During treatment, your general dentist or endodontist (a dentist who specializes in problems of the pulp) removes the diseased pulp. The pulp chamber and root canal(s) of the tooth are then cleaned and sealed. Once the root canal system is sealed, a gold or porcelain crown is placed over the tooth to protect it from breaking.
Howlong will the restored tooth last?
Your restored tooth could last a lifetime, if you continue to care for your teeth and gums. However, regular checkups are necessary. As long as the root(s) of a treated tooth are nourished by the tissues around it, your tooth will remain healthy.
