Psst: Philips Sonicare—and More Top-Rated Electric Toothbrushes—Start at Less Than $50 During Amazon Prime Big Deal Days

When we put this sleek, battery-powered toothbrush to the test, the result was cleaner teeth. Its secret is its handy timer function, which signals exactly how long to spend on each area of your mouth until it shuts off after two minutes. "I feel like I’m making a difference in my dental hygiene routine with an aesthetically-pleasing toothbrush to boot," Associate Editor Chelsea Candelario explains.

Most importantly, the vibration and speed (it only has one standard pace) "aren't overpowering, and its curve-shaped bristles are soft, which is a must for folks with sensitive teeth," Candelario writes. The bonus is the price (particularly today), the case to store it in and the replaceable brush heads (it comes with two).

This rechargeable model reportedly operates for 90 days on a single charge, so it should be great for travel. And more than 13,000 5-star ratings sing its praises as "the" up-and-coming oral care brand to buy on Amazon. One reviewer touts the five different brushing modes, including sensitive, which they described as "Gentle as a breeze, making it suitable for those with sensitive teeth. You can customize your cleaning experience to suit your preferences effortlessly."

It also comes with six extra replacement bristles—that's handy because the brand recommends changing every three months for optimum dental health. Compared with the Philips One rechargeable ($45), which reportedly only stays charged for one-third as long, we're tickled pink about picking up this one for less than half the price.

Think you don't need Bluetooth in a toothbrush? Think again. "We are all thinking that the idea of a Bluetooth toothbrush is funny but it really encourages me to brush my teeth, my tongue and floss much more often," writes one reviewer. "It does little beeps and awards for consistently using it, which is rewarding. I'm MUCH more consistent about doing the entire routine than ever before." All this, for 45 percent off retail (and it's way less than the comparable Philips Sonicare Diamondclean, $209, that's more than twice the price on sale).

Thanks Oral-B—for the motivation, the pressure sensor that protects teeth and gums from excessive brushing pressure, as well as the reminder when it's time to replace the brush head. We're smiling brighter already!
