How many teeth are found in deciduous dentition?

Deciduous dentition, commonly known as primary or baby teeth, consists of a total of 20 teeth. This set of teeth is typically less than the number present in the permanent dentition due to the absence of premolars and certain molars, which develop later.

In a full primary set, there are 10 teeth in each quadrant: two incisors, one canine, and two molars. This arrangement leads to the total of 20 teeth that make up the entire deciduous dentition. These primary teeth play crucial roles in facilitating proper chewing, language development, and guiding the eruption of the permanent teeth that will replace them as the child grows. Understanding the composition of deciduous dentition is important for dental professionals, as it informs treatments and expectations for dental development in children.
