Child Growth and Development Review (CGDR) Practice Test 2026 - Free CGDR Practice Questions and Study Guide

Most children typically lose their first tooth around the age of 6 years. This milestone is part of the natural development process, where primary teeth, also known as baby teeth, begin to fall out to allow for the eruption of permanent teeth. The lower central incisors are usually the first to go, often making an appearance around this age.

This age range aligns with the developmental timelines of dental growth and loss observed in children. By age 6, children are also often entering or are already in the early stages of school, which can coincide with increased peer interaction and social dynamics related to tooth loss, making this an important developmental milestone. The process continues for several years, with children generally losing their last baby teeth between ages 12 and 13. Understanding these timelines is key in monitoring children's health and development appropriately.
