Frequently Asked Questions

Who's behind Fancy Floss?
We're Katie, a practicing dentist (Creighton University Dental School, 2020), and Jacquie, a quality assurance professional with a biochemistry background. We spent years working in our respective fields before deciding to tackle the oral care waste problem ourselves.
How does the refill system work?
The container has a side-opening mechanism. Pop it open, swap the spool, close. Takes about 10 seconds. No threading, no tools, no frustration.
What sets this apart from conventional floss?
Italian-manufactured using premium materials engineered not to shred or fragment. The refillable architecture eliminates monthly plastic waste. And the design is minimal enough that you'll actually leave it on your counter.
What's the sustainability story with the container?
Recycled plastic construction, designed for multi-year use. You keep the dispenser indefinitely and only replace the consumable spools — reducing plastic waste by roughly 90% compared to traditional monthly containers.

Our Story

It started at Dolores Park in San Francisco. My friend Katie and I were taking a break, enjoying the weather and a Mission burrito. Our conversation drifted to oral hygiene — as it does when you're friends with a dentist.

Katie graduated from Creighton University Dental School in 2020 and built her practice in San Francisco. I'm Jacquie — I studied biochemistry and spent years doing quality control stuff across different industries. When a piece of meat got stuck between my teeth, I asked Katie for her professional recommendation on the best floss available.

As serial flossers, we were both frustrated with the options available in the market. Traditional floss shreds and gets stuck between your teeth. The sustainable options weren't much better. Nothing looked good enough to leave on the bathroom counter. But what really got to us was the floss pick problem — those little plastic Y-shaped picks scattered on sidewalks, parking lots, parks, even at Dolores Park itself. Single-use plastic designed to be thrown away after 30 seconds of use. It's disheartening to see people toss them on the ground so carelessly, adding to the 3 billion floss picks that end up in landfills and oceans every year.

We identified the problem: the overuse of plastics in oral care and the throwaway culture of single-use floss picks. Katie knew what patients actually needed from her years treating them. My background in quality control gave me some useful perspective on what makes a product work well and last.

So we made Fancy Floss. A refillable container made from recycled plastic that you use again and again — not a single-use pick you throw on the ground. Luxurious mint-waxed floss from Italy that glides like silk. If we could create something that makes people more cognizant of their plastic usage, maybe we could make a small difference.

That's it. Just better floss from two friends who got tired of the waste.
