Complete answer:
The study of teeth is known as dentistry. Teeth are present in both the jaws as semicircular arches. The teeth embedded in pits, the sockets or alveoli, of the jawbones named maxilla and mandible. Such teeth are called thecodont. The number of teeth is fixed and they are produced in two sets: temporary, milk or deciduous and permanent. The milk teeth appear during the first two years after birth, beginning at the age of about 6 months. They are ahead after some time and are replaced by permanent teeth between 6 to 12 years. The teeth that appear in two sets are called diphyodont. There are four types of teeth incisors, canines, premolars, and molars. The incisors have sharp, chisel-like cutting edges and are also called the cutting teeth. They occur at the anterior ends of the jaws. The canines are pointed and occur next to the incisors. The premolars and molars are called grinding teeth. They have broad and grooved tops and are located further back in the jaws.
