A set of teeth play an important role in your ability to eat, speak, and stay healthy. There are 32 teeth in an average adult. These 32 are further divided into four types depending on their functions, and their development. These are:
The eight front teeth in a person’s mouth, four on top and four on the bottom are called incisors. Out of these four, the middle two are called central incisors, while the ones on sides are called lateral incisors. These help in biting the food. Even babies have them and they get replaced by permanent incisors once the primary incisors fall out between the ages of six and eight.
There are four canines placed just after incisors. There are two, each on the top and bottom for both children and adults. The primary canines appear when a child is between 1 to 2 years of age and the permanent lower canines come at around 9 years while upper canines take another 2-3 years and erupt between 11 and 12 years of age.
Also known as bicuspids, they are used for chewing and grinding of food. There are four premolars on each side, two each on the upper and lower jaw. These are somewhat flat with ridges on top. The first premolars appear around the age of 10.
The teeth used for chewing and grinding are called molars and they are stronger than premolars. These are 12 in numbers and are located at the rare end of the mouth. The deciduous molars or primary molars as they are called start erupting when the child is 12 to 15 months old. The permanent molars which are eight in number, four each on upper and lower jaw do not replace any of the primary teeth. They start erupting from the age of 6 and the process continues till the age of 12 up to 13.
Taking good care of these basic set must be a priority. Therefore, brush once in the morning and at night to keep those cavities at bay.
