How do I use a Sensodyne toothpaste?

The Sensodyne website recommends that people with tooth sensitivity brush normally with Sensodyne toothpaste twice each day. Tooth sensitivity that persists despite regular use of Sensodyne for several weeks may indicate a problem that requires professional treatment.

Sensodyne toothpaste contains potassium ions that surround nerves in the teeth and prevent the transmission of nerve impulses that cause pain from sensitivity. Sensodyne Repair and Protect formulas utilize stannous fluoride to create a protective layer over exposed dentin to keep painful stimuli from accessing the nerve of the tooth. Sensodyne also offers a ProNamel formula that aids in re-hardening tooth enamel that has softened.
