Sensodyne has created and developed a whole line of toothpastes and toothbrushes to meet various demands. For those who have sensitive teeth in particular, good cleaning is essential to preventing plaque buildup and reducing further wear and tear that may result from overbrushing. The Sensodyne Expert toothbrush was created by professionals specifically to clean teeth gently and thoroughly. Its cross-active, soft bristles are specifically engineered to effectively clean teeth while being kind to gums and teeth. When cleaning hard-to-reach regions, this toothbrush's bristle tips are 20 times thinner than those of a standard flat trim manual toothbrush.
