Amazon's sixth annual Holiday Beauty Event kicked off on Oct. 19, and I've been scouting out the best deals from the sale. If you and your roommate or live-in partner need new toothbrushes, you're especially in luck: A bundle of two Philips Sonicare DiamondClean 9000s is on sale for half off as part of the event.

These smart electric toothbrushes usually sell for $399.99 as a pair (or $199.96 on their own), but right now, you'll only pay $199.93 total. That's a record-low price, according to the Amazon price-tracking site camelcamelcamel.

Rated highly by Amazon reviewers for its cleaning performance and value, the Sonicare DiamondClean 9000 has four adjustable brushing modes and a built-in pressure sensor. (It'll vibrate if it thinks you're brushing too hard.) If you're really trying to optimize your dental health — teeth-maxxing? — you can track your brushing habits using its companion mobile app. Philips says it can last up to 14 days on a single charge.

Amazon's BOGO offer applies to the bundle that includes rose (light pink) and white variants of the Sonicare DiamondClean 9000. Both come with their own travel cases.
