    The Sensitivity Rescue

    Potassium-nitrate paste (Sensodyne-type)

    Keeps a whitening routine comfortable enough to finish.

    No commission

    We earn nothing on this one.

    No affiliate programme exists for Potassium-nitrate paste (Sensodyne-type) anywhere, so there's no link to give you and nothing in it for us. It's here because the protocol calls for it. Buy it wherever you already shop.

    What to look for is in the notes below — that's worth more to you here than a link would be.

    Role-vetted pick Evidence-graded Protocol-matched

    Why it's in the protocol

    Potassium nitrate calms the nerve response so sensitivity doesn't make you quit mid-routine. The companion to any whitening step.

    The Protocol verdict

    “Not a whitener — the reason your whitening routine stays comfortable enough to finish.”
