Baby teeth typically begin to fall out around the age of 6 years. Children usually lose their central incisors first—the lower central incisors come out around 6 to 7 years old, followed by the upper central incisors. The process of losing baby teeth continues with lateral incisors, canines, and molars, usually completing by about age 12. By the time a child is around 12 years old, most will have lost all 20 baby teeth, which are then replaced by permanent adult teeth. The timeline can vary, with some children losing their first baby tooth as early as 4 years or as late as 7 years old, and it is generally normal for the process to last from about 6 to 12 years of age.
