Arrangement Of Teeth And Different Types Of Teeth
Teeth are an essential part of the human body, as they help in the process of chewing and breaking down food for digestion. Apart from this, teeth also play a crucial role in speech and enhancing the facial aesthetics of a person. In this article, we will discuss the arrangement of teeth and the different types of teeth present in the human mouth.
Arrangement of Teeth
The arrangement of teeth in the human mouth can be categorized into two types: primary teeth and permanent teeth. Primary teeth are also known as baby teeth, which start to appear in the mouth at the age of six months. These teeth are replaced by permanent teeth, which begin to emerge at the age of six years.
The human mouth consists of a total of 32 teeth, which are arranged in a specific pattern. The teeth in the upper jaw are slightly larger than those in the lower jaw. In each jaw, there are two incisors, one canine, two premolars, and three molars on each side. The arrangement of these teeth allows for efficient chewing and breaking down of food.
Different Types of Teeth
There are four different types of teeth present in the human mouth, each with a unique shape and function:
Incisors
Incisors are the front teeth in the mouth, which are used for biting and cutting food. There are four incisors in the upper jaw and four in the lower jaw. They have a sharp, chisel-like edge, which helps in cutting through hard and fibrous foods.
Canines
Canines are the sharp, pointed teeth present next to the incisors. They are used for tearing and ripping food apart. There are two canines in the upper jaw and two in the lower jaw. They have a long and pointed tip, which helps in piercing through tough and chewy foods.
Premolars
Premolars are the teeth present between the canines and molars. They have a flat surface, which helps in crushing and grinding food. There are four premolars in the upper jaw and four in the lower jaw.
Molars
Molars are the large, flat teeth present at the back of the mouth. They have a broad surface, which helps in grinding and crushing food. There are six molars in the upper jaw and six in the lower jaw. The last molars that emerge in the mouth are called wisdom teeth, which usually appear between the ages of 17 and 25.
Conclusion
Teeth play a vital role in the human body, and their arrangement and type are crucial in the process of digestion. Understanding the different types of teeth present in the mouth can help in maintaining good oral hygiene and preventing dental problems. Regular brushing and flossing, along with dental check-ups, can ensure healthy teeth and gums.
