Do children replace their large teeth (molars) when they lose their baby teeth?

Introduction
If the “large teeth” in children refer to primary molars—including the first and second primary molars—they will generally be replaced. This replacement process is typically completed between ages 10 and 12. However, some children may have congenital absence of permanent teeth. If “large teeth” refers to permanent molars—such as the first, second, or third permanent molars—these teeth will not be replaced.
Under normal circumstances, children’s primary molars (often referred to as “large teeth”) are replaced during the mixed dentition phase; however, exceptions exist.
If the “large teeth” refer to primary molars—including the first and second primary molars—these are typically replaced by permanent teeth. This replacement usually occurs between ages 10 and 12. However, in some children with congenital absence of corresponding permanent molars, the primary molars may persist without being replaced.
If “large teeth” instead refer to permanent molars—namely, the first, second, and third permanent molars—these teeth will not be replaced later in life. The first permanent molar generally erupts around age 6; the second permanent molar emerges between ages 9 and 11; and the third permanent molar (wisdom tooth) erupts much later—usually after age 18—and some individuals never develop it at all.
If a child exhibits any dental abnormalities, prompt medical evaluation is recommended to avoid delays in diagnosis or treatment.
