Philips Sonicare Essence HX5351

The Philips Sonicare HX5351 is a rechargeable, battery-powered toothbrush that provides up to 14 days of use per every 24-hour charge period. It features Sonic technology with dynamic cleaning action for enhanced oral hygiene & gum care, and contour-fit bristles that adjust to angled tooth surfaces for easier access to hard-to-reach areas.

Also included is an automatic shut-off function that encourages no more than 2 minutes of brushing, and a battery indicator. Hundreds of users say the HX5351 is able to reach all the teeth without a user having to stick their entire hand in their mouth. Unfortunately replacement heads can be expensive. And toothbrush residue is prone to easily accumulating inside.
