Are electric toothbrushes any good, especially when it comes to whitening teeth?

The most effective electric toothbrush is Sonicare because the toothbrush is gentle, reduces plaque, and whitens teeth.

According to, the brush strokes per minute of brushing methods can be compared as follows:

a. Sonic toothbrush: 30,000 to 40,000

b. Conventional electric toothbrush: 2,500 to 7,500

c. Basic hand brushing: 300

The Sonicare website at, reports that there have been over 140 studies of Sonicare. Some key findings:

1. The Sonicare Flexcare is clinically proven to remove significantly more plaque than Oral-B Sonic Complete and Oral-B Triumph.

2. Sonicare toothbrushes are clinically proven to reduce gingivitis and improve overall gum health.

3. The dynamic sonic technology is proven to remove extrinsic (coffee,tea, and tobacco) stains and also helps naturally whiten teeth by up to 2.5 shades in 2 weeks.

4. Sonicare is demonstrated to be safe and gentle for those with sensitive teeth and gums.
