All of you have been to school, right? So all of you would be knowing how many teeth do humans have? Well, you would have answered it perfectly right by saying 32 adult teeth.
Now, do you know how many teeth do you have in your mouth keeping in mind the ones that are removed, damaged, broken, fallen, etc? If not then do have a count as we would go ahead and explain the anatomy of a tooth.
Every tooth is made up of 3 different layers namely – Enamel, Dentin, and Pulp.
The outermost layer of the tooth is called enamel which is visible and white in colour. It is a protective layer of the teeth. The enamel is known to be the hardest tissue in the entire body.
The mid-layer of the tooth is called dentin which is just like bone and also serves the same purpose as it gives structure to the tooth. There are millions of tubes that connect to the tooth’s life source called the pulp.
This is the living source of the tooth known as the core which means the innermost layer. It is made up of nerves and blood.
Apart from the main 3 layers of the teeth the part that is just above the gum line is called the crown and the one below the gum line is called the roots that are attached to the jawbone.
How many teeth do adults have?
Right from the age of 5, milk teeth known as the baby teeth start falling and the permanent teeth start growing. Adults as we all know have 32 teeth which are gained by the time we reach our teenage years.
All the adults have Incisors, Canines, Premolars, and Molars. Here are the total number and types of teeth in an adult.
The front 4 teeth at the top and the bottom are called incisors which are sharp and thus let you hold, bite, or cut your food. They can sense the texture of the food too.
4 Canines or Cuspids:
The corner pointed teeth at both right and left, up and bottom corners are called canine teeth, or cuspids. They help in tearing or grabbing the food easily.
The teeth between the canines and molars are called premolars which cut and tear food.
There are 12 molars in total with 4 up and 4 down to grind and mush the food before finally being swallowed. The remaining 4 molars are the wisdom teeth that come as you enter your 20s or 30s.
Take care of your teeth
Each of your tooth has its own designated function which it performs during the childhood and adulthood.
Your responsibility here is to take good care of your teeth and keep your gums healthy in order to avoid cavities and other dental issues.
