The mouth is a small but important part of our human anatomy. It is responsible for many functions including eating, drinking, speaking and of course showing off a beautiful smile! Here is a quick overview of the parts in our mouth and the roles they play:
Incisors – these are the chisel-shaped front teeth (four upper, four lower). They are sharp and used for cutting food.
Canines – these are shaped like points and are used for tearing and grasping food.
Premolars – these have two pointed cusps (biting surface), used for crushing and tearing food.
Molars – have several cusps on their surface to help with grinding and chewing food.
Crowns – these are the top parts of the tooth and the most visible part to the eye. The shape of the crown plays a part in the tooth’s function. For example the front teeth are sharp for cutting and molars have flat surfaces for chewing and grinding.
Gum line – this is where the tooth and gums meet. Plaque can build up at the gum line and lead to gingivitis or gum disease if proper routine brushing is not done.
Enamel – is the outer layer and hardest part of the tooth.
Dentin – is the layer under the enamel of the tooth.
Pulp – is the soft tissue found in the centre of all teeth. This is also where the nerve tissue and blood vessels are located.
