Probing inside a tooth

Before we delve into the grey teeth problem and its solutions,first we need to have a basic knowledge about a tooth’s general structure.That way it will be easy for you to understand the problem and its solution.

So a tooth is divided into three layers. Those are:

  1. Enamel:It is the most outer part of a tooth.It mostly consists of minerals.Its main duty is to ensure the protection of both dentin and pulp.
  1. Dentin:It is the middle layer of a tooth.It mostly consists of hollow like tubules.
  1. Pulp:It is the most inner layer of a tooth.It consists of blood vessels and nerves.

Types of grey teeth occurring

A grey teeth occurring can happens in two ways:

  1. Wide spread color change to all teeth: This widespread color change can happen due to teeth staining.And this is maybe caused due to tooth development or due to aging.
  1. A noteworthy color change in a single tooth: This is caused by trauma.It is also known as dental trauma. Like when your knee turns blue or black after getting hurt somewhere. Your tooth also turns grey when you receive trauma to your tooth.

Mechanism of grey teeth occurring 

First of all this can happen due to improper care of your teeth. If you don’t care for your teeth properly,then teeth will lose their functionality causing grey teeth occurring.

Mechanism of grey teeth occurring

Or this can happen due to some kind of infection.This phenomenon  can take place in a single tooth or multiple teeth.

When your tooth receives trauma or gets infected,the nerve and the blood vessels in the pulp get damaged.Similar to the way when you receive a bruise and the bruise changes its color in due time,the dead and the blood vessels within the pulp chamber of the tooth undergo a degradation process.Thus changing its color and causing grey tooth occurring.

  1. Opening: Opening is done through the enamel and dentin into the pulp chamber.
  1. Cleaning: After the cleaning is done,fluid is put in the canals to remove any kind of bacteria and it also helps to rinse the debris out.
  1. Pulp remove: After the cleaning,pulp is removed from the tooth. Then using the small instrument they clean and shape the canals.
