Did you know that your teeth are composed of multiple layers named as dentin and enamel? The outer layer is called enamel that protects teeth against physical and chemical injury. It is known as the toughest tissue in our body even tougher than bone. Enamel act as the first line of defence for the teeth against food and bodily fluids we are exposed to. The wear and tear caused by the chemical are called enamel erosion.
Wisdom teeth, also known as third molars, are the last teeth that come into the mouth in the adult dentition. Usually, there are four of them located far behind in the ultimate position of your jawbones. For years now, they have been called wisdom teeth because they first appear during the wisdom age, between 17 and 25.
