The arrangement, number, and type of teeth in the mouth. In young children, primary dentition comprises 20 teeth (incisors, canines, and molars). These teeth are replaced between the ages of 7 and 13 years by secondary (permanent) dentition. Secondary dentition comprises 32 teeth (incisors, canines, premolars, and molars). The third molars (wisdom teeth) may not erupt until 18–21 years of age. (See also eruption of teeth.)
