When a tooth dies, it means that the pulp inside the tooth, which contains nerves and blood vessels, has become infected or damaged to the point where it can no longer survive. This can happen due to various reasons, including severe decay, gum disease, or trauma, such as a tooth being knocked. A dead tooth can lead to pain, discolouration, and swelling if left untreated.

Endodontic Treatment

Endodontic treatment, commonly known as a root canal, is a dental procedure used to save a tooth that has a dead or dying nerve. The process involves:

Accessing the Pulp: The dentist or endodontist makes an opening in the crown of the tooth to access the pulp chamber.

Removing Infected Pulp: The damaged or infected pulp is carefully removed.

Cleaning and Shaping: The root canal system is cleaned and shaped for filling.

Filling the Canal: The empty canal is filled with a biocompatible material, typically gutta-percha, to prevent reinfection.

Sealing the Tooth: The opening of the tooth is sealed with a filling, and often a crown is added for extra protection.

What is an Endodontist?

An endodontist is a dentist who specializes in treating diseases and injuries of the dental pulp and surrounding tissues. They have additional training beyond dental school that focuses on diagnosing and treating tooth pain and performing root canal treatment and other procedures related to the interior of the tooth.

How a Tooth Dies After Being Knocked

When a tooth is knocked, it can damage the blood vessels and nerves in the pulp. If the trauma is severe enough, it can immediately cut off the blood supply, leading to the death of the pulp. In other cases, the damage might lead to gradual dying of the pulp over time. Without treatment, a knocked tooth can develop an infection, leading to an abscess, pain, and further complications.

Prompt dental treatment following a tooth being knocked is crucial. Sometimes, if attended to quickly, the tooth can be saved, and further complications can be prevented.
