Where Is Flaus Electric From Shark Tank Season 15 Today?

Most of us don't think that much about flossing. In fact, you may not know how often you really need to floss. You might even say you'd rather scrub dishes or toilets than floss, like many people who took a 2015 survey from the American Academy of Periodontology (via NPR). Why, then, is the Flaus Electric Flosser getting so much positive buzz from critics? Ask entrepreneur Samantha Coxe, a flossing tool founder who swam in the Shark Tank on season 15.

Coxe's backstory follows a familiar Shark Tank pattern: A founder experiences a problem, looks for a solution, can't find one, and fills the market gap with a new or better product. For Coxe, getting 12 cavities despite being a regular tooth brusher led her to want to start flossing, which led her to work with experts to design and patent an electric flosser that would make flossing easier. Picture a traditional electric toothbrush with what looks similar to a disposable flossing pick at the end instead of a bristled brush. That's the basic Flaus silhouette: a sleek, functional plastic wand outfitted with removable, recyclable heads.

Three sharks bit when Coxe explained that she had already sold $900,000 in the past year. But she didn't get the $250,000 in exchange for 5% equity she wanted. After some haggling with Candace Nelson, Kevin O'Leary, and Daymond John, she relinquished 8% equity to Nelson for the quarter-million-dollar asking price. And her decision seems to have paid off.

Coxe's flossing innovation has been earning some high praise since her May 2024 episode. A Popsugar reviewer admitted that after a Flaus session, her mouth "felt noticeably cleaner" because Flaus decently removed hidden between-teeth debris. And she appreciated that Flaus heads were designed to be eco-friendly, although the mail-in recycling program Flaus offers didn't seem convenient.

A comparison in a Esquire article between Flaus and a similar product from Slate was equally glowing. For the reviewer, the difference between devices was obvious: "In the areas where Slate let me down, Flaus picked up the slack." He noted that an embedded bite pad helped the flosser work floss effectively between typically hard-to-reach molars.

Meanwhile, a CNN review called the Flaus "fun." The reviewer claimed to have used a Flaus for more than a year (which means she began before the Shark Tank airing) and added that Flaus has updated its collection to include white and pink models. A quick peek at the Flaus shop confirms that a Flaus Starter Kit comes in three colors. (However, there are only two shades of Flaus replacer flossing heads: white and black.)

This type of flossing feedback lines up well with a 2022 review of power-driven dental cleaning devices published in Clinical and Experimental Dental Research. The reviewers determined that, when combined with manual brushing, using a powered interdental tool improved patient gingival health and compliance outcomes.

Adding a Flaus to your daily oral hygiene practices could be one of the many ways to prevent tooth cavities — as well as the shock of receiving a preventable high dental bill (like Coxe received after her multi-cavity diagnosis.) Plus, Flaus-ing seems to elevate flossing from a dreaded chore to at least a palatable task. (Here are some mistakes everyone makes when flossing their teeth.)

However, you can't necessarily run out to your nearest retailer to get a Flaus. As of April 2025, you can only purchase a Flaus on their brand site or through Amazon. That said, you may be able to catch a special bargain from time to time, such as the holiday deal advertised on Nelson's Instagram in November 2024. At the time, she starred in a reel advertising a Flaus holiday deal. The deal is no longer available, but the post hints that Nelson isn't just a silent partner but an active advocate.

This kind of support from Nelson started when she and Coxe sealed their relationship in the tank. It was then that Nelson averred, "I am going to give you operational support, strategic support, [and] emotional support." It would seem that Nelson has lived up to her promise and that Flaus is continuing to build momentum.
