What is the concentration of Rx Fluoride Toothpaste?

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

Answer: (D)

Prescription fluoride toothpaste is formulated for patients at higher risk for caries, so it contains a much higher fluoride level—about 5000 ppm, which is roughly equivalent to 1% sodium fluoride. This stronger concentration provides greater remineralization support and helps prevent decay in individuals with elevated risk, enamel vulnerabilities, or xerostomia. In contrast, over-the-counter toothpastes typically deliver about 1000–1500 ppm fluoride and are intended for general prevention. The other numbers listed don’t reflect the standard prescription product, so the 5000 ppm option is the correct choice.
