Kate McKinnon disrupts strangers' bathroom visits to push away the Philips Sonicare toothbrush

The series, titled “Sonicare Switch,” aims to bring toothbrush users out of the Stone Age — especially those who still hand-hold their manual toothbrushes.

In the first of four ads, McKinnon takes on the role of Susan Toothbrush, a chic and somewhat unexpected guest who disturbs unsuspecting people in their most private moments – brushing their teeth.

In the ad, a man, toothbrush in hand, is preparing for an important job interview when McKinnon suddenly appears and questions his choice of an “old bristle wand.”

The star expressed her excitement about the partnership, saying, “I'm very excited to work with Philips Sonicare to motivate people to make the Sonicare Switch.” The most important thing is what you think about yourself, and it was a Naturally, encouraging people to switch to a Philips Sonicare – like I did. Plus, I never miss the opportunity to go into people’s bathrooms when they least expect it.”

The brand believes McKinnon was “the perfect complement” to the advertising message, said Matina Vidalis, senior marketing director for consumer and professional oral health at Philips North America. “Her enthusiastic energy and unmatched comedic talent help people rethink their current brushing habits and switch to more effective oral care.”

The work promotes Philips Sonicare's electric toothbrush portfolio, which includes devices such as the Sonicare 6100, Sonicare 4100 and the high-end DiamondClean Smart 9300 toothbrush – which, according to the brand, remove up to 20 times more plaque from the gum line can.

“Whether you're going to an important job interview or taking a big step in your relationship, at Philips Sonicare we want you to be equally confident in yourself and your oral health products,” said Vidalis.

As the campaign unfolds, viewers can expect to see McKinnon's character advising couples settling into their first home, interview candidates and everyone in between to take advantage of this newfound dental technology.

The Sonicare Switch campaign was created with the help of creative agency FleishmanHillard. It will run in the US and Canada over the next few months and appear on the brand's website, emails and social media. Consumers can also find it in stores and on various paid media channels.
