The study is intended to verify through clinical measurement that the NUPRO Sensodyne Prophylaxis Paste with Novamin provides immediate sensitivity relief as well as extended relief up to 28 days.

It is hypothesized that the prophy paste with NovaMin(r)will give patients immediate sensitivity relief, as well as sensitivity relief up to 4 weeks (28 days) after measurement.
