What is the concentration range for OTC fluoride toothpaste (Sodium Fluoride or Stannous Fluoride)?

• A. 12,300 ppm
• B. 9,050 ppm
• C. 1000-1500 ppm
• D. 5000 ppm

Answer: (C)

OTC fluoride toothpaste is formulated to deliver a safe, effective amount of fluoride for daily use. The fluoride concentration in these products is typically around 1000–1500 ppm fluoride ion (as F-). This range provides caries-preventive benefits when brushing twice daily while keeping the risk of fluorosis low for children when used as directed. Higher concentrations, such as about 5000 ppm or even 12,300 ppm, are found in prescription or professional products, not in standard OTC toothpaste. So the best fit is the 1000–1500 ppm range.
