Dentistry — dentistry The practice of dentistry involves preventing, diagnosing, and treating oral disease, as well as correcting deformities of the jaws, teeth, and oral cavity.

In humans, the primary dentition—also known as the set of deciduous or baby teeth—is usually complete by the age of 2 1/2 years.1

This primary set consists of 20 teeth in total, comprising four incisors, two canines, and four molars in each jaw. These teeth typically begin to appear around six months after birth and are eventually shed between the ages of 5 and 13 as they are replaced by permanent teeth.1
