Best Electric Toothbrushes

They've been evolving constantly since our last test in 2008. We brushed up on eight fresh models, from a supermarket steal to a top-of-the-line buy. Here, three that came out sparkling.

This rechargeable ($220, amazon.com) wins the day for its "super-sleek" design, power ("like a pressure washer"), and extras, including a second brush head and a glass that doubles as a charging station. Five quiet modes make for a customized clean.

The SmartGuide smiley-faced timer earned fans: "It made me brush longer," said one. Users loved the Oral-B's ($160, amazon.com) pressure sensor but not the brush's heaviness. The holder stores four brush heads.

BrushPoint Oscillating Clean Power

At this price, switching from manual is a no-brainer (though users preferred rechargeables). This cheapie ($4, amazon.com) has a strong motor and a design that makes it easy to reach back teeth. Though feature-free, it held a charge the longest.
