A recent study found that baby teeth can provide valuable information about a child's brain development. By examining the layers of these teeth, researchers can identify the metals children were exposed to during pregnancy. This study followed nearly 500 children in Mexico City and linked their tooth analysis to brain scans and behavior assessments, revealing critical insights into how environmental factors affect development.
