How many deciduous teeth are in a primary dentition?

Explanation:
In primary dentition there are 20 deciduous teeth. There are ten teeth in each arch, and in each quadrant there are five teeth: two incisors at the front, one canine beside them, and two molars at the back. No premolars or wisdom teeth are present in this set, which is why the total is twenty. This is the stage of development where the mouth hasn’t yet formed the permanent teeth, so counts larger than twenty reflect later dentitions (mixed dentition, when some permanent teeth have erupted, or the full permanent set).
