How does Sensodyne work?
Sensitivity is caused by a permanent condition called exposed dentin. Dentin has little holes that lead to the nerve center of the tooth. Sensodyne travels down the holes (or tubules) and creates a barrier around the nerve and, with regular brushing, builds long lasting protection. Sensodyne works at the source of the pain to calm and sooth the nerve and is clinically proven to relieve the pain of sensitivity. Dentists recommend using Sensodyne twice a day just as you would use your normal toothpaste.
