The Oral B Black 7000 is a high-end electric toothbrush designed by Braun that retails for nearly $300 -- toothpaste not included. Boasting up to 48,800 rotations per minute (RPM), it promises to remove double the plaque of a manual toothbrush. But is it any better than a $20 electric toothbrush?
The Oral B Black 7000's main claim to fame is its German engineered power handle that allows the head to oscillate an impressive 48,000 times per minute. This works out to around 220,000 rotations during a five minute brushing session. (By contrast, most people only manage 300 strokes per minute with a manual toothbrush.)
Other noteworthy features include six separate brush modes (Daily Clean, Deep Clean, Whitening, Gum Care, Sensitive and Tongue Cleaning), inbuilt Bluetooth (more on which later) and a range of pressure-sensors that automatically adjust the rotation speed to suit your brushing style. You also get a SmartGuide timer that works in conjunction with the toothbrush.
As you'd expect from a $299 toothbrush, the Black 7000 comes with some extra bells-and-whistles bundled inside its ridiculously huge box. These include the aforementioned SmartGuide timer, a protective carry case, a faux leather pouch and three detachable brush heads: CrossAction, FlossAction and ProWhite.
Personally, we feel Oral B should have included two of each brush head so that families could share the device straight out of the box. As it stands, you'll need to go out and buy some more brush heads straight off the bat. Tch.
Using the Black 7000 immediately erased any doubts about the product's quality. It honestly feels similar to receiving a professional clean in a dentist's chair, although part of that may have been down to my extra-strength toothpaste. In any event, the speed and sheer power of its oscillations comfortably put other electric toothbrushes I've tried to shame.
The inbuilt sensors trigger a red warning light when you push too hard and also slow down the RPM until you ease off. Battery life is rated at six to seven days in-between charges. This seems surprisingly low for a device that is only used a few minutes per day. Then again, 48,800 RPM obviously requires a lot of power.
In addition to timing your brushing sessions, the wireless SmartGuide includes vital stats on its LED display such as the mode you're using and the teeth areas that still need brushing. It also rewards you with a star rating at the end of each brush. To be honest we're not massively enthused by this gizmo but we suppose it could be handy for kids or forgetful users.
All in all, the Oral B Black 7000 is certainly a cut above the average electric toothbrush. Whether it's worth the astronomical asking price is highly debatable, however. If you're paranoid about oral hygiene we suppose it could be a worthy investment. With that said, you can get similar results from a normal toothbrush -- it will just take much, much longer.
