It goes without saying that many people take their teeth for granted. When people are young, they have several other things to think about than their teeth. So, they will take great care of their physical appearances, they will eat healthy food and exercise regularly to keep themselves in good shape.

Unfortunately, not many people accord such importance to their teeth or oral hygiene. As a result, when things go wrong, the situation usually becomes quite serious.

Many people will probably know that all the teeth in their mouths do not share the same appearance. There are different types of teeth in the mouth, with each type serving a specific purpose.

When the dentist or orthodontist examines a patient’s mouth, they will typically come across the following types of teeth:

  • Canines (or Cuspids): These teeth will have sharp, pointed ends. They are useful for tearing tough food items such as meats.
  • Incisors: The average person has eight incisors, with four situated in each arch of the mouth. These sharp teeth help in cutting food easily.
  • Molars: These teeth help in grinding food, thereby making it easier to digest. Given their role, it is easy to see why these teeth experience the greatest amount of stress. Dentists often exhort patients to pay a lot of attention to the molars while brushing and flossing.
  • Premolars (or Bicuspids): The premolars lie between the molars and the canines. They serve to crush and tear food into smaller particles.

As mentioned earlier, different types of teeth exist in the mouth. Each type of tooth varies in its appearance and function. Despite this, all teeth comprise similar parts.

A visit to any cosmetic dentist in Fairfield or other places will serve to confirm this. The human tooth typically comprises:

  • The Crown: This is the uppermost part of the tooth. It makes up the visible portion of your smile. It is worth highlighting that although each tooth has a crown, not all of them serve the same purpose.
  • The Enamel: Teeth usually comprise three layers. The enamel layer is the one that remains the most visible. This translucent layer is among the hardest substances in the human body. Despite this, the enamel layer can wear out over time, leading to tooth sensitivity or decay.
  • The Dentin: This layer lies directly beneath the enamel layer. It serves to provide an additional layer of protection. On occasions, the dentin could become apparent when you observe a yellow discolouration in your smile.
  • The Gumline: This lies at the place where the teeth and the gums meet. Dentists often urge patients to brush and floss regularly. Failure to do this could lead to the build-up of plaque. Over time, this could cause gingivitis and other types of gum diseases.
  • The Root: The root of your teeth remains embedded in the alveolar bone. This usually makes up two-thirds of the entire tooth.
  • The Pulp: This refers to the soft tissue found in the centre of the tooth. The enamel and the dentin protect this as it houses the nerves and blood vessels. Please call us on 02 9727 0364 to find out more!
