Inside the tooth, there is a hollow center containing pulp, which is commonly referred as the nerve of the tooth. This is comprised of a sensitive tissue made of blood vessels, connective tissue, and nerves that supply oxygen, nutrients, and feeling to the tooth. The pulp is found throughout the tooth, and the space between the pulp is called the root canal.
Root canal treatment is a dental procedure that replaces a damaged tooth or infected and/or inflamed pulp with a filling. Root canal treatment is needed for a cracked tooth, for a traumatic dental injury, and for added retention of a crown.
Root canal is necessary when the tooth gets decayed, which is caused by bacteria. Pulpitis is the inflammation in pulp against bacteria. Irreversible pulpitis is described as the level of inflammation in which the pulp tissues will not recover and heal. This eventually will lead to dead nerves or an infected pulp, followed by a dental abscess.
During a root canal, the inflamed or infected pulp is removed. After that, the inside of the tooth is carefully cleaned and disinfected. The canals are filled and permanently sealed with a rubber-like material called gutta-percha. This keeps the canals free from infections or contaminations. Later, the tooth is restored with a crown or a filling for protection. When this restoration is completed, the tooth is able to continue its function like any other tooth.
Endodontic treatment, or root canal treatment, can help maintain your natural smile as well as help you continue eating the foods you love. With proper dental care, most teeth that have had root canal treatment can last a lifetime.
