The main function of human teeth is breakdown of food Into smaller pieces which further helps in digestion of food. Teeth are considered to be the strongest part of human body. Teeth are made from proteins such as collagen, calcium and other minerals. Apart from chewing the food it also helps us to speak properly. Total number of teeth are 32 in an adult They are divided as 8 incisors, 4 canines which are also called cuspids, 8 premolars also called bicuspids, 12 molars which include 4 wisdom teeth.
Our human teeth are divided into 4 parts:
Incisors-
The Incisors are our front 8 teeth. These teeth helps us to bite our food. They have sharp edges and are also shaped like small chisels. When we bite an apple we use our Incisors teeth.
Canines-
Canines are the next teeth that develop in one’s mouth. We have total of four Canines teeth and they are your sharpest teeth, which is used for tearing apart food. When after biting an apple with help of Incisor teeth after that Canine further helps to chew.
Premolars-
Premolars help us to tear our food. And also helps to crush them into small pices. They have flat biting surface. There are total of 8 Premolars.
Molars-
These teeth are considered to be the largest amongst the all. Their function is similar to the premolars, helps to grind, tear, and also crush the food. There are total of 12 molars, out of which 4 develop during age period of 18-25. One might or might not have 4 molars which develop in later stages. It can also be a painful process to experience.
People don’t really take care of their teeth. They take them for granted. One should really look after their teeth as it is very important part of our body.

What are the different types of teeth?
The teeth are divided into different types based on their shapes and utility in our mouth for various activities. Their placement is as such done in was that helps them to solve the purpose at its best.
Here is the list to type of teeth with their brief activity:
1. Incisors
These are present at the front side of our mouth. They have sharp edges and are placed at front to help break food item into smaller parts. We all have 8 incisors, 4-lower jaw and 4-upper jaw.
2. Canines
These are placed at the corner of the dental arc. They are sharp and appear pointy. The main function of these is to hold grip or tear food. We have 4 canines, 2-lower jaw and 2-upper jaw.
3. Premolars
These are placed right behind the canines. Comparatively, these are flat in shape and have ridges. The main purpose of these is to crush the food particles. We have 8 premolars, located 2 on each side of the jaws.
4. Molars
These are the largest and strongest of all. These have large and flat surface. These are used for grinding the food particles. We have 12 molars, 6 in each jaw.
5. Wisdom tooth

Teeth are the elementary part of our digestive system. When food goes inside our mouth with the help of the teeth, we bite the food particles and break them down to smaller particles so that it can be mixed well with the saliva and can even pass the esophagus. Teeth are composed of calcium and are also the hardest part of our body, they are set up on the gums through roots and blood capillaries. It is also subject to decay, if not taken proper care teeth can cause great problems even, which will further lead to digestive and gastric problems are the very basic part of the digestion process will be hampered. One should brush atleast twice a day and use mouthwash and regularly floss in between of the teeth.
There are basically four kinds of teeth which human being possess:
1. Incisors: There are a total of eight incisors, four in the upper jaw and four below they are used basically for cutting leafy things and vegetables.
2. Canines: There are a total four canines, two in each jaw they are used for tearing meat and other tough food items.
3. Molars: There are a total eight molars four in each jaw their job is to grind the food into particles.
4. Pre-Molars: There are a total of eight pre-molars and their functionality matches those of the molars.

Teeth are present in the buccal cavity. These masticate food, that is, chew food and cut them into smaller parts that can be taken inside through the food pipe. The saliva in the mouth gets mixed with the masticated food and this ball of food is now known as the bolus. It is adviced that food should be chewed properly to avoid any indigestion. The food that gets broken into smaller pieces with saliva mixed in it, has an increased surface area and makes it easier for the digestive juices to act on the food and digest the essential nutrients. These nutrients are then absorbed and the waste materials, in turn, are passed out.
Thus, this was the importance of teeth. Following is the classification of teeth –
Humans have four types of teeth –
1. Incisors
2. Canines
3. Pre molars
4. Molars
Incisors –
These are the pointed teeth present in the front. The teeth generally visible when we smile.
These are used in cutting and biting food.
It is pointed and chisel shaped.
Canines –
These are more pointed than the incisors
They are also used in cutting and tearing of food
In non – vegetarians these are highly pointed as they are required to cut and tear the flesh
pre molars –
the are used for crushing the food, that is, for chewing purposes
these contain 2 cusps and are smaller than molars
these are absent in children
molars –
these mark the ends of the jaws
these contain 4 – 5 cusps
these are required for chewing and crushing of food
the last molars are regarded as wisdom tooth. Don’t go with the name, it does not bring wisdom, but it develops after a certain age, an age where the person is mature and wise, i.e., usually after the age of 17.
numbers –
an adult human being has the following number of teeth
· 8 incisors
· 4 canines
· 8 pre molars
· 12 molars
The formula for calculation of teeth is – (2*1*2*3) / (2*1*2*3) where this marks the half portions of upper and lower jaws.
Thus, this was the classification of teeth in human beings. I hope this helps.
