What is the maximum concentration listed for OTC fluoride rinses?

• A. 200 ppm
• B. 1000 ppm
• C. 900 ppm
• D. 0 ppm

Answer: (B)

Fluoride concentration on mouth rinses is labeled in parts per million (ppm), which tells you how much fluoride is in each liter (or per unit volume) of rinse. For over-the-counter products, the highest strength you’ll commonly see listed is about 1000 ppm fluoride, which aligns with roughly a 0.2% sodium fluoride preparation. This level represents the upper limit that consumer OTC rinses typically carry on the label, balancing effectiveness with safety for general use. So, 1000 ppm is the maximum concentration commonly listed for OTC fluoride rinses. Lower values like 200 ppm or 900 ppm are real concentrations you might encounter, but they’re not the maximum, and 0 ppm would mean no fluoride at all.
