The Emmy-winning comedian teamed up with Philips Sonicare for a new marketing campaign designed to inspire you to make “The Sonicare Switch.” McKinnon, already adored for eccentric roles like Weird Barbie, "Holtz" in the new Ghostbusters franchise, and at least 10 SNL characters, now takes on the role as Susan Toothbrush, a cheeky, well-meaning oral health enthusiast.

Her message is clear: it’s time to go electric, and Philips Sonicare is here to convince you why.

Why Switch?

We get it—switching from a manual toothbrush to an electric one might feel like a small change, but it can actually make a big difference for your oral health. Philips Sonicare, the number one dentist-recommended power toothbrush worldwide, is leading the charge (obviously, pun intended).

I've already made the switch, and the difference is notable. Not only do Philips Sonicare and McKinnon highlight that an electric toothbrush can remove up to 20 times more plaque than manual brushing, but it can also deliver more brush strokes in two minutes than you’d get in an entire month with your manual toothbrush. We'd say that's a pretty efficient way to upgrade your oral care game and target plaque removal.

For First-Time Electric Brush Users

If you’re still hanging on to that manual brush, you’re not alone. Many people are hesitant to switch to an electric toothbrush because they assume the old-fashioned way is good enough, especially if the dentist delivers a freebie at each cleaning appointment. But here’s the deal: an electric toothbrush model can reach spots your manual one misses including spaces between teeth. Plus, Philips Sonicare brushes are designed to be gentle on your gums, so if you have sensitive teeth or a delicate gumline, know that the transition is smooth and easy.

Already Have an Electric Toothbrush?

For those of you who’ve already made the switch, Philips Sonicare has a few more tricks up its sleeve. Advanced models like the DiamondClean Smart don’t just brush—they give you real-time feedback through an app, track your brushing habits, and even let you know when it’s time to replace your brush head. (If you're already into closing your rings or monitoring your sleep health, this is a natural addition to your routine. We love when a simple oral health routine goes beyond a two-minute timer.)

Beyond the Brush

“Whether heading into a big interview, or taking a big step in your relationship, at Philips Sonicare we want you to feel equally confident in yourself and your oral healthcare products,” said Matina Vidalis, Senior Marketing Director, Consumer & Professional Oral Healthcare, Philips North America. 

She adds, “Working with Kate has been the perfect pairing. Her enthusiastic energy and unmatched comedic talent are helping empower people to reconsider their current brushing habits and upgrade to a more effective oral healthcare regimen.”

McKinnon’s playful ads may make you laugh, but the message is serious: your oral health matters. Toothbrush manufacturers continue to tout that electric toothbrushes are clinically proven to improve gum issues, help you have whiter teeth, and deliver confidence. As McKinnon herself puts it, how you feel about yourself is what matters most, and your smile plays a big part in that.

Are you on the fence? I've been an electric toothbrush user for over 20 years, and I couldn't go back. Whether you're a newbie to electric toothbrushes or looking for an upgrade, now's the time to make The Sonicare Switch. You’ll be doing more than just brushing your teeth—you’ll be investing in a healthier, brighter smile.
