What Is A Dead Tooth?

A dead tooth comprises dead nerves owing to a lack of blood supply to the pulp, which is the inner centre part of the tooth. When blood supply is cut off from the pulp, the nerves become damaged and the tooth begins to die because it isn’t receiving the necessary oxygen and nutrients to remain healthy. This also invites harmful bacteria build-up and a greater chance of infection. The tooth will eventually fall out by itself.

Symptoms Of A Dead Tooth

The dentist is best placed to identify and determine the root cause of a dead tooth. Although, there a certain symptoms that you’ll experience that will draw your attention to a tooth that is beginning to decay or is slowly dying.


Sensitivity in and around the tooth is the first sign of a dead tooth. The pain can be minor to severe. This is because the centre of the tooth has become infected and swollen, putting pressure on the periodontal membrane, which is the nerve tissue formed around the tooth base. This can cause immense pain. Bacteria or dead nerves builds up inside the pulp cavity.

Change of Colour

A tooth that is showing signs of changing colour is a sign that there is a lack of blood supply to the tooth. The tooth colour can change from yellow to black. The discolouration will continue until you get treatment from the dentist. Signs of a colour change of the tooth will also introduce swelling, bad odour in the mouth and inflamed sores on gums.
