In the past, if you had a tooth with a diseased nerve, you’d probably lose that tooth. Today, with a special dental procedure called root canal treatment, you may save that tooth. Inside each tooth is the pulp and the nerve. The nerve is the vestige of the tissue that originally formed the tooth. Once the tooth has been in the mouth for a time, the functioning of the nerve is no longer necessary.
When a tooth is cracked or has a deep cavity, bacteria can 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 the pulp tissue to die. When the infected pulp is not removed, pain and swelling can result. Certain byproducts of the infection can injure your jawbones and your overall health. Without proper root canal treatment, your tooth may have to be removed.
