There is absolutely no need to be worried if your dentist suggested a root canal procedure to treat a damaged or diseased tooth. Root canal treatment is necessary when parts of your tooth become inflamed or diseased. Inside your tooth, beneath the enamel and dentin, is a soft tissue called pulp. This tissue contains blood vessels, nerves and connective tissue, which help grow the root of your tooth during its development.
When the pulp becomes inflamed or infected, treatment is needed. The most common causes of pulp inflammation or infection are a cracked or chipped tooth, a deep cavity, or other serious injury to the tooth. All of these can allow bacteria to enter the pulp. If damaged or infected pulp is not removed, the tissues around the root of the tooth can become infected. Pain and swelling often result. Even if there is no pain, bacteria can damage the bone that holds the tooth in the jaw. A fully developed tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.
Your teeth are meant to last a lifetime. Years ago, diseased or injured teeth were usually pulled. When a tooth is removed and not replaced, the teeth around it may shift. This can make biting and chewing difficult and may make it harder to clean your teeth. Areas that are not cleaned well are more likely to get gum disease. Root canal treatment can prevent these problems by saving your natural tooth. Also, root canal treatment is usually less expensive than a replacement tooth.
Root canal therapy helps you maintain your natural smile, continue eating the foods you love and limit the need for ongoing dental work. With proper care, most teeth that have had root canal treatment can last a lifetime.
