Not all toothbrushes are created equal, and Colgate seems keen to show just how that’s the case, with the world’s first toothbrush that uses an accelerometer to work out the best speed to brush your teeth.

What is it?

Colgate’s latest electric toothbrush isn’t like your regular electric toothbrush.

Oh sure, it can take different heads, designed to tackle different sensitivities of teeth, and it still uses an accelerated up down motion from an electric motor to drive everything, working at a rate of up to 32,500 strokes per minute, but there’s more to it than that.

For starters, this toothbrush has sensors to change the motion based on the position you’re holding the toothbrush, which consequently affects what teeth you’re brushing.

Three modes are built into the unit for brushing.

The “auto” mode changes between slow strokes for the surface of the tooth facing either the tongue or cheek, medium speed for the tooth margin connecting to the gums (seemingly interdental), and a fast motion for the tops of your teeth.

The second mode is “optimum” and works in the middle speed, while the third mode “deep clean” operates on that fast mode. Only the “auto” mode runs the slower mode for the sides of the teeth.

A two minute timer runs the length of your brush session, pausing momentarily every 30 seconds to tell you to change quadrants.

Charging the toothbrush is handled with an induction charger, plugged into the wall, with the NiMH

battery a replaceable one found at the bottom of the toothbrush handle.

A case is included with the tooth brush, as is both a sensitive head and two triple cleaning heads.

Performance

Given how long the electric toothbrush has been around, it’s a wonder that manual powerless toothbrushes are still a thing.

In fact, it’s actually been over 50 years since the first one was conceived, and there have been numerous developments over the past few years to improve it substantially, generally with faster motors designed to whirr and move the brush head with very, very fast motions.

Colgate’s latest attempt on the gadget we’re surprised not everyone owns one of is to engage Omron, a provider of sensor technology (among other things) and install sensors in a toothbrush to work out what teeth you’re brushing at the time and provide a more comprehensive and accurate brushing.
