14. Name different types of teeth and their number in an adult human.
Answer
In an adult human, four different types of teeth are found. These include incisor, canine, premolar and molar teeth.
1. Incisors: The eight teeth in the front are incisors. There are four incisors each in the upper jaw and the lower jaw. The function of incisors is the cut off food particles.
2. Canines: The pointy teeth on either side of the incisors are canines. They are four in number, two each placed in the upper jaw and the lower jaw. They are meant for tearing.
3. Premolars: These are the teeth next to the canines. They are eight in number, four each placed in the upper jaw and the lower jaw. Their function is grinding.
4. Molars: These are found at the end of the jaw, next to the premolars. There are twelve molars, six each placed in the upper jaw and the lower jaw.
