The Plaqless Pro’s other trick is that its sensors create a “map” of your mouth and transmit that data back to your phone so you can see exactly where you’ve brushed and what spots you’ve missed. I feel like you need to be really dedicated to your oral health to take advantage of that data, but it’s there if you need it. The app also contains the requisite feedback and coaching tips based on how you brush — again, something that’s probably overkill for most people.

Colgate isn’t saying when the Plaqless Pro will go on sale or how much it’ll cost, but it will be more expensive than the company’s current electric brush, the $100 E1. Colgate says it will be in the same realm as top-of-the-line options from Oral-B and Sonicare, which should put it in the $200 range. That’s a big commitment, but immediate feedback on how clean your teeth are is something buyers should be able to immediately find useful.
