Explanation of Endodontics
Endo is the Greek word for “inside” and odontis Greek for “tooth”. Endodontic treatment covers the inside of the tooth. To understand endodontic treatment, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves, and connective tissue and creates the surrounding hard tissues of the tooth during development. The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root.
Why would I need an endodontic procedure?
Endodontic treatment is necessary when the pulp, the soft tissue inside the root canal, becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, or a crack or chip in the tooth. In addition, an injury to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess, and potentially, you could lose the tooth.
What are the signs of needing endodontic treatment?
Signs to look for include pain, prolonged sensitivity to heat or cold, tenderness to touch and chewing, discoloration of the tooth, and swelling, drainage and tenderness in the lymph nodes, as well as nearby bone and gingival tissues. In rare cases, however, there are no symptoms.
Can all teeth be treated endodontically?
Most teeth can be treated and saved. Occasionally, a tooth can’t be saved because the root canals are not accessible, the root is severely fractured, the tooth doesn’t have adequate bone support, or the tooth cannot be restored. However, advances in endodontics are making it possible to save teeth that even a few years ago would have been lost. When endodontic treatment is not effective, endodontic surgery may be able to save the tooth. Your dentist will discuss this with you.
What causes an endodontically treated tooth to need additional treatment?
New trauma, deep decay, or a loose, cracked or broken filling can cause new infection in your tooth. In some cases, the endodontist may discover additional, very narrow or curved canals that could not be treated during the initial procedure, and so a second procedure is necessary.
