Query: Best Electronic Toothbrush

Take cae of your teeth and gums with this elecronic toothbrush. The new design with the angled head makes brushing your teeth easier. Also, the new smaller brush design is better. After using this for a few months, your dentist and/or periodontist will be able to tell the difference. When the "pockets" in your gums around the teeth are measured, you will be amazed at the improvement. Highly recommended, and worth every penny.
