    Prescription-Strength Fluoride — Ask Your Dentist

    PreviDent 5000 / Clinpro 5000 (Rx)

    The strongest enamel defense — dentist-gated.

    Ask your dentist — we don't sell this.

    This tier is prescription-only. Bring it up at your next visit — the conversation costs nothing, and your dentist can judge whether you need it.

    Role-vetted pick Evidence-graded Protocol-matched

    Why it's in the protocol

    For high-risk enamel or severe dry mouth, 5000ppm prescription fluoride is the clinical step. That's a dentist conversation, not a cart.

    The Protocol verdict

    “The strongest enamel-defense tier is prescription-only — we route you to your dentist, we don't sell it.”
