Overview

Deciduous teeth are the first set of teeth. They develop during the embryonic stage of development and erupt during infancy. They are usually lost and replaced by permanent teeth. The deciduous dentition is made up of central incisors, lateral incisors, canines, first molars, and secondary molars.. All of these are replaced with a permanent counterpart except for the first and second molars; they are replaced by premolars. The deciduous teeth will remain until the age of six. Permanent teeth are the second set of teeth. Their eruption starts at the age of six years and is completed at eighteen to twenty-five years. Grown-ups have 32 permanent teeth, of four different teeth types. There are sixteen at the maxilla and sixteen at the mandible: 8 incisors, 4 canines, 8 premolars and 12 molars. Wisdom teeth appear later in life. They are located in the very back of the mouth.
