In terms of anatomical structure, kennedy square Brampton is sure that you are curious and want to know what a tooth really looks like. Well, every tooth can be divided into three main parts:

  • Tooth crown
  • Tooth neck
  • Tooth root

Tooth Crown

The part of the tooth that is visible is called a tooth crown. The crown covers the tooth enamel. There are five different areas of each and every crown of the tooth and they are:

  • Vestibular surface – the surface of the teeth that touches the cheeks and the mouth
  • Tongue surface – the surface of the teeth that touches the tongue
  • Distal surface – the surface that allows contact with neighboring teeth
  • Biting surface – the teeth surface used for chewing

It may sound complicated, but it is not. Teeth have a very simple and easy to understand structure. Depending on the type of teeth, the chewing surfaces have bumps and pits that are intended for chewing and cutting food.

Neck of The Tooth

The neck is the part of the tooth where the enamel and the cement of the root canal meet, so according to that this part is usually called the enamel – cement junction. Physiologically speaking, this part of the tooth cannot be seen because it is covered with tissue.

The root of the tooth

The root of the tooth is the fragment located in the jawbone. It is completely covered with cement. The size of the tooth root depends on the size of the tooth. The frontal teeth have only one root, while other teeth have two and three roots. The material of the roots is very important when it comes to reparation of teeth. It is important to keep it healthy in order for each treatment to be successful.

Histological structure of the tooth

From a histological point of view, we can divide teeth into four parts:

  • Enamel
  • Dentin
  • Cement
  • Pulp

Enamel

The enamel represents the hard part of the tooth and it is the part that keeps our teeth healthy and protected. It consists of materials and elements that make it very hard and resistant to different kinds of acids we enter with food. The enamel covers the whole tooth.

Dentin

The dentin is the largest part of the tooth and has almost the same composition as the enamel. It is consisted of tubules and when they get irritated it can affect the sensitivity of the tooth. The color of the dentin is yellowish and gray. The difference between enamel and dentin is that the dentin is produced during our whole lives.

Cement

The cement is another mineralized tissue that is very similar to the bones in our body. It covers the top part of the teeth and has a canalicular structure.

Pulp

The pulp is the only soft tissue of the tooth. It consists of blood vessels, fibers and cells and is surrounded by dentine.
