How many teeth constitute the primary dentition?

The primary dentition consists of a total of 20 teeth, which are divided evenly between the two arches—10 in the maxillary arch (upper jaw) and 10 in the mandibular arch (lower jaw). These primary teeth include incisors, canines, and molars, specifically comprised of 4 incisors, 2 canines, and 4 molars in each arch.

This foundational knowledge about the primary dentition is crucial for understanding the development of children's dental health and for planning appropriate dental care during the early years. The numbers in the other choices either misrepresent the total count of primary teeth or incorrectly divide them between the arches. It’s important for dental professionals to be well-versed in the anatomy of primary teeth to ensure accurate assessments and interventions related to pediatric dental care.
