Why is enamel thicker on deciduous teeth than permanet teeth?

Enamel is generally thicker on deciduous (baby) teeth compared to permanent teeth because these primary teeth are designed to withstand the forces of chewing during early childhood, when children are still developing their oral habits. The thicker enamel provides increased protection against wear and decay as these teeth are used more intensively during their shorter lifespan. Additionally, the development of permanent teeth occurs beneath the primary teeth, leading to differences in enamel thickness as the two types of teeth serve different functional and developmental roles.
