Snag an Oral-B electric toothbrush for $90 off and keep your breath minty fresh

SAVE $90: If the dentist has been tsking at your teeth, you may want to try an electric toothbrush for a more thorough clean. The AI-powered Oral-B Genius X Limited is a great option, and it's on sale at Amazon. As of Feb. 2, grab it for $109.99 (original price: $199.99) — a savings of 45%.

Fillings suck, and extractions are even worse. Ward off both with a smart electric toothbrush that cleans between the gaps, plus tells you where to brush and for how long.

The Oral-B Genius X Limited is designed to recommend the ideal brushing routine for oral hygiene that also fits your own brushing style. It provides coaching via a Bluetooth-connected app that shows you where you've already brushed and where you should focus, detecting your toothbrush's movement with its motion sensors. It's also sensitive to pressure, and will warn you when it decides that you're brushing too hard.

With six cleaning modes, the Oral-B Genius X Limited offers customized solutions for your toothbrushing goals. A full charge lasts two full weeks of twice-a-day, two-minute sessions of brushing, so you can take it on vacations without even packing the included charger. It even has a 360° SmartRing with LED lights, in case you wanted an aesthetic brushing experience.
