The practice of dentistry involves preventing, diagnosing, and treating oral disease, as well as correcting deformities of the jaws, teeth, and oral cavity.
In human dentition, primary teeth—also known as baby, milk, or deciduous teeth—typically begin to appear when the first tooth erupts at approximately six months of age. By the end of the first year, an infant usually has six erupted teeth, consisting of four upper incisors and two lower incisors. The emergence of these teeth is a significant developmental milestone that allows infants to transition from consuming soft foods to coarser ones.12
