Periodontal disease can cause you to lose your precious teeth. Preventing this requires that you care for your periodontal pockets by brushing them properly. Doltz brushes feature a unique 3-mm difference in brush height to fit even narrow periodontal pockets, so the brush tips do not enter more than is necessary, and therefore don’t cause pain or injury to your gums. What’s more, the linear sonic vibration provides the type of horizontal brushing recommended by dental hygienists, which enables Doltz to successfully removes plaque from periodontal pockets. Panasonic’s Doltz has been No. 1*. in sales in Japan for six straight years. It is the most beloved electric toothbrush in Japan.
