Teeth are an essential part of the human body. Apart from aiding in the process of mastication, teeth also help in speech and maintaining the shape of the face. Teeth are divided into three classes based on their arrangement in the mouth. In this article, we will discuss the class 1, class 2, and class 3 teeth arrangement.

People with class 2 teeth arrangement have a prominent upper jaw, and their chin appears to be receding. This type of arrangement can cause some difficulties in chewing and may also affect speech and facial appearance.
