The teeth: how they are made and what their functions are
The teeth consist of the following components:
- the enamel, which represents the most superficial and hardest part of the tooth
- the dentin, below the enamel, which represents the hardest part of the tooth
- the pulp, which contains the nerves, is the organ responsible for the vitality of the tooth itself
- the root, which still the tooth in the maxillary bone
These different layers make the teeth represent the most resistant part of our body, which, however, can be affected by the bacteria present inside the oral cavity: this is why it is fundamental to observe a correct oral cavity hygiene, in order to keep your teeth healthy and strong.
With their different shapes the teeth are distinguished in incisors, canines, premolars and molars.
Each type of tooth has a different function in chewing:
- the incisors are used to cut food
- the canines are useful in tearing up food
- the premolars are used to break down food
- the molars are used to chew food and reduce it in very small parts before swallowing.
All teeth together, of course, work to enable us to eat all the different types of food.
Children’s teeth are smaller to accommodate the size of the oral cavity and reduced jaw bones; they start to appear around the age of six months and complete the training around the age of three.
During the growth these teeth begin to fall (around six years) to leave space for the definitive teeth: in fact, it is very important since the first years of childhood to observe an oral hygiene as scrupulous as possible, using a toothbrush and a fluoride toothpaste, so as to strengthen the teeth and keep them healthy.
