Then maybe it is time to consider a mechanical toothbrush. With the latest changes in technology have come some amazing and highly effective tools to clean your teeth and keep your smile healthy. Most mechanical toothbrushes come with rotating or oscillating heads. The heads are self-powered and work much like a wax polisher works on the floor or your car. As the bristles are pressed against teeth and gums, the rapid, constant movement removes plague and food particles.
Sonic toothbrushes have a rotating head and bristles, but in addition emit sound waves.
The sound waves create a vibration that helps, in conjunction with the bristles, to loosen and plague and particles. This is the same technology that your dentist uses in the office to help remove plague. As you can tell after a professional cleaning, sound waves can be very effective. The next type of toothbrush is the Ionic Toothbrush. Ionic toothbrushes work by reversing the polarity of the teeth.
