Do you have occasional tooth twinges? Do you notice sudden, short bursts of sensitivity? If so, it could be a sign that your teeth have vulnerable areas of exposed dentine, a primary cause of sensitivity. It's possible to repair those areas. Sensodyne Repair & Protect contains patented NovaMin® technology, which seeks out and forms a tooth-like layer over vulnerable areas of the tooth where dentine is exposed. Use twice a day, every day, to continuously help repair*, strengthen and protect your teeth from sensitivity.
