What is the medical name for baby teeth, usually lost by 6 years of age?

The medical name for baby teeth is "deciduous teeth." These are the first set of teeth that develop in children's mouths, typically beginning around six months of age. Deciduous teeth usually start to fall out around the age of six as they are gradually replaced by permanent teeth. The term "deciduous" literally means "falling away" or "tending to fall off," which accurately describes how these teeth are eventually shed to make way for the permanent teeth.

The other options refer to different types of teeth. Permanent teeth are the adult teeth that replace deciduous teeth. Wisdom teeth are the third molars that usually emerge in late adolescence or early adulthood. Cuspid teeth, also known as canine teeth, are a specific type of permanent tooth located next to the incisors. Understanding these terms helps clarify the different stages of dental development in humans.
