Our teeth are meant to last a lifetime. Sometimes, however, damage occurs to a tooth (often from a deep cavity or an injury that causes a tooth to crack) and the inside of the tooth becomes infected. This infection damages the pulp of the tooth – the network of blood vessels and nerves inside.
Root canal is a procedure done to save the damaged or dead pulp in the root canal of the tooth. This is done by cleaning out the diseased pulp and reshaping the canal, which is then filled to prevent recontamination of the tooth. The tooth is then permanently sealed, with possibly a post and/or a crown made of porcelain or metal alloy. This enables you to keep your original tooth. It may take multiple sittings based on your dentist recommendation.
Root canal procedure is not painful!
