Even with the huge discount, you might be (understandably) skeptical about spending $100 on a toothbrush, but trust us when we say this appears to be worth the splurge.

Reviewers have said this investment into their oral health has been “worth every penny” and even helped them save money on dental bills in the long run.

The Genius X Limited is more high-tech than your average electric toothbrush. Not only does the brand claim that it can remove up to 100% more plaque than your standard manual toothbrush, but thanks to AI brushing recognition, you can use Bluetooth to track your brushing habits with the Oral-B app. It can actually give you personalized coaching to make sure you’re brushing everywhere you need to, for how long you need to, with the right amount of pressure.

Talk about a toothbrush that works for its money.

The trusty device has five cleaning modes, a visible pressure sensor so you don’t press too hard and risk damaging your teeth and gums and a two-minute timer so you’re always brushing long enough. Your purchase comes with a convenient travel case and one replacement brush head — according to the brand, each brush head should last you up to 90 days with regular brushing. Reviewers also say that charging this toothbrush makes it last longer than others they’ve used in the past, about two weeks.
