What is root canal therapy?
Have you been told you that you need root canal therapy? If so, you’re not alone. Millions of teeth are treated and saved each year with root canal, or endodontic, treatment. Root canal is a scary phrase for most people, but it doesn’t have to be. The actual root canal treatment shouldn’t cause pain; in many cases it relieves it!
The pulp of the tooth is located inside the tooth, under the white enamel and a hard layer called the dentin. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development. A fully developed tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.
Sometimes damage occurs to the pulp of a tooth. This is usually caused by deep decay, injury that caused a tooth to crack, or a large or deep existing filling/crown. Endodontic treatment involves making a small opening in the biting surface of the tooth, removing the damaged pulp, cleaning, shaping, filling and sealing the tooth. In most cases, a crown will be recommended on this tooth after root canal therapy to protect it from fracturing.
