Sonic-FX Duo electric toothbrush comes with charcoal-infused nylon bristles designed to clean teeth with an impressive 40,000 strokes per minute, more than other common electric toothbrushes and infinitely more than manual toothbrushes. This version of the Solo includes 12 standard brush heads plus 2 interdental heads. This toothbrush has 3 brushing modes for a customized brushing experience: Super for deep cleaning, Normal for daily cleaning, and Massage for gum stimulation. The toothbrush is also programmed to spend the ADA-recommended 30 seconds on each quadrant of your mouth for a total of 2 minutes. The toothbrush will notify you every 30 seconds so that you go onto the next quadrant, and it stops automatically after 2 minutes.

The proprietary brush head design has longer bristles along the perimeter and different height bristles in different areas to reach deeper in between teeth and clean teeth better. Twist & lock feature makes it quick and convenient to replace brush heads.

The toothbrush is super lightweight, making it much more comfortable to use than others. This also makes it perfect for children. Being rechargeable means you can carry it anywhere, especially when traveling. 

Sonic toothbrushes are highly recommended by dentists to patients all over the world because of their performance in dental care and the comfort they provide and they also massage the gums more than regular toothbrushes.
