root canal treatment
Root canal treatment (endodontics) is a dental procedure used to treat infection at the tooth pulp that is inflamed, infected, or dead. Root canal treatment is not painful and can save a tooth that might otherwise have to be removed completely.
The infection at the root canal is caused by bacteria that live in the mouth and invade the tooth. This can happen after tooth decay, leaky fillings, damage to teeth as a result of trauma, such as a fall. Root canal treatment is only required when dental X-rays show that the pulp has been damaged by a bacterial infection. The pulp will begin to die if it’s infected by bacteria, allowing the bacteria to then multiply and spread.
