Teeth are one of the strongest parts of your body that are composed of minerals like calcium and phosphorus. The number of teeth in your mouth varies as you grow older. Most adults have 32 teeth and children have all their 20 primary teeth by the age of 3. Adults have 8 incisors, 4 canines, also called cuspids, 8 premolars, also called bicuspids and 12 molars, including 4 wisdom teeth. While children have 4 incisors, 2 canines and 4 molars.
There are mainly four types of teeth. The incisors at the front of the mouth are used for cutting or shearing food into small chewable pieces. The canines function is to grip and tear food, these are situated at the 'corners' of the dental arches. The premolars have a flat biting surface which also helps to tear and crush food. There are eight molars in the primary dentition and twelve in the permanent dentition, these are considered as the largest of the teeth.
Wisdom teeth are the last of the molars to come between the ages of 17 and 25 years. Each set of teeth has a different role and their own function.
