In a sea of mediocre sales, there is reason to smile.

The best electric toothbrush Amazon Prime Day 2021 has to offer represent but a sliver of the oral care products on sale right now. Sure, an electric brush is programmed to give you the perfect pressurized and timed scrubdown. (They also have motorized heads that more thoroughly remove plaque and reduce gingivitis.) But while you're shopping, why not pick up some terrific teeth-whitening strips at rarely-seen-before prices, along with a high-powered water flosser that'll run rings around standard floss? If you're ready to make the upgrade, or if you want to gift any of these to your partner or friend, then here are a couple deals on the best electric toothbrush, flossers, and teeth whiteners we plucked from the all of the deals going down during Amazon Prime Day 2021.

    Crest 3D Whitestrips Professional Effects

    This is THE sale in this category. Whiter teeth are just a click away—20K reviews with 4.5-star average can't be wrong.

  • 2/7

    Crest 3D Whitestrips with Light

    That being said, Crest also makes these—the LED lights-inclusive version. You'll see the kind of results you only used to get going to a professional.

    Philips Sonicare DiamondClean electric toothbrush

    The DiamondClean is an absolutely ridiculous electric toothbrush, in a good way. It’s got an extremely powerful motor and comes with an app that tracks how well you’re cleaning, along with five different brushing modes. But none of that is as important as the fact that you charge it by just tossing it in this beautiful glass cup. It’s a luxury, for sure, but at a slightly less luxurious price during Prime Day.

    Oral-B Genius X electric toothbrush

    Oral-B's Genius X toothbrush offers a slew of powerful brushing “modes,” and it even coaches your brushing technique as you use it to make sure you aren't missing the back of your molars, for example. The Diamond Clean does this slightly better, but the Genius X is cheaper during Prime Day. Your call.

    Waterpik WP-660 electric water flosser

    45,000 reviews confirm that this is one of the single best ways to clean the plaque and grime between your teeth.

  • 6/7

    AuraGlow teeth whitening kit

    A slightly more complicated and intense (but very effective) teeth-whitening kit. Instead of applying strips, you wear a mouth guard injected with gel. If that sounds like a good time, have at it.

  • 7/7

    Colgate "Optic White" toothpaste (2 pack)

    Colgate's whitening paste uses a 3% hydrogen peroxide formula and promises to remove "10 years of yellow stains." Add it up—that's a lot of coffee and red wine!
