teeth

Humans have four types of teeth: incisors, canines, premolars and molars, which each have specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw)

or the mandible (lower jaw) and are covered by the gums.

Are teeth are very delecat so we need to make sure we look after them and brush them twice a day.
