BISSELL Little Green Mini Cordless Portable Deep Cleaner

While I once scoffed at the idea of electric toothbrushes, I’ve definitely come to see the benefit of using them over standard brushes – and this smart DiamondClean 9300 model takes things even further with more personalization and guidance. There are four different brushing modes to utilize here, alongside three intensity levels, all to get your pearly whites clean and ready to show off to the world.

There is a light ring on the end of the handle that flashes to alert you when you’re exerting too much pressure or not enough, and by connecting it to the Philips Sonicare app, you’ll even gain guidance on how to maintain and/or improve your habits. Along with the brush, you’ll also be getting an all-in-one brush head, a C3 premium plaque control brush head, a charging glass and stand, and a travel case.

If you’re not in need of all the fancier app-based bells and whistles the above model offers, you can also pick up the Philips Sonicare 4100 Rechargeable Electric Toothbrush for $34.96 shipped, after clipping the on-page $5 off coupon. This model has been serving me well for years, coming with a more simple pressure sensor, a 2-minute timer, and Quadpacer tech that keeps track of brushing done in each quadrant of my mouth.
