Primary teeth, also known as deciduous or baby teeth, typically begin to erupt at about 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 eruption of these teeth is a significant developmental milestone that allows children to transition from consuming soft foods to coarser ones.1
