Excess Toothpaste: Child's IQ at Risk, New Research Claims

• A JAMA Pediatrics study links prolonged toothpaste exposure or swallowing to weakened child IQ.
• Fluoride in toothpaste, if kept in mouth too long, can harm developing brains and act as a neurotoxin.
• Excess fluoride can lead to dental fluorosis, skeletal fluorosis, and reduced learning ability.
• Research suggests a 1.63 point IQ drop for every 1 mg/L increase in urinary fluoride.
• Parents should use rice-grain sized toothpaste for under 3s, pea-sized for 3-6 year olds, and teach spitting.
