If we look at the structure of the tooth we will understand how staining of the tooth occurs. Through years and years of wear and tear the tooth becomes stained as foods, drinks and other substances allow plaque and staining to occur. It’s interesting to understand the structure of the tooth in order to get a better understanding of how this occurs.
There are four tissues that make up the tooth, the enamel, dentin, cementum and pulp. The enamel is the outer area of the tooth and acts as the protection and barrier for the tooth. It is the strongest part of the tooth. The enamel area has no living cells and therefore the human body cannot reproduce any cracked or chipped parts of the enamel. As this occurs the tooth must be reconstructed by a dentist. The enamel protects the tooth in its daily use, chewing and biting.
Inside the enamel is the dentine area, it’s softer than the enamel but also helps to protect the tooth. As the dentine is softer it is more susceptible to decay. Cavities can occur in the dentine area which may cause rapid decay of the tooth. This area of the tooth should be cared for properly and checked regularly. The dentine area is responsible for the colouring of the tooth. Sometimes the enamel is mistaken for the area that produces colour in the tooth. In fact the enamel is a translucent tissue.
Stability of the tooth comes from the cementum. The cementum is again one of the softer tissues that makes up the tooth. At the apex of the tooth the cementum is strongest. Finally the pulp contains all the nerves and blood vessels in the tooth. When you feel sensitivity and tooth ache it is due to the pulp area of the tooth.
Main causes of staining:
Build up of plaque due to poor hygiene
Antibiotics taken during development of teeth
