Most people hate flossing because it’s awkward, messy, and hard to reach the back teeth.

Glissi uses gentle sonic vibrations through a reusable soft floss head that slides between your teeth — just like normal floss — but without the finger wrapping or awkward angles.

Unlike a water flosser that sprays water everywhere, Glissi gives real contact cleaning with far more control and zero mess.

Think of it as the electric toothbrush of flossing — same results, but 10x easier.

Great question — and yes, it’ll feel tight at first (just like normal floss).
That’s because tight contacts are tight for every kind of floss — which is usually why people stop flossing in the first place.
Glissi isn’t a “magic” flosser that slips through every gap effortlessly — it’s a smarter, cleaner way to make the habit easier overall.
The tapered, waxed heads and sonic vibration help the floss glide in with control instead of force, so over time it feels more natural.
For some tighter areas, you might need a small wiggle motion — but once it’s through, it’s gentle, smooth, and satisfying.
Glissi doesn’t make flossing perfect — it makes it possible for people who’ve struggled to stay consistent.

Yes — Glissi is flossing, just made effortless.
Dentists recommend flossing once a day, and Glissi makes that habit realistic.

It turns a chore into a 60-second routine, so you actually keep doing it — without the frustration, bleeding, or guilt that comes from skipping.

Traditional floss is cheap — but so is the experience.

Most people don’t floss consistently because it’s painful, messy, and time-consuming.

Glissi isn’t about replacing floss; it’s about finally building the habit — through comfort, control, and design you’ll actually use.

Think of Glissi like an electric toothbrush — the heads are designed to be reused, but eventually, they wear down or collect buildup depending on your mouth and habits.
How long a floss head lasts depends on:
How tight your contacts are

Whether you have crowns, fillings, or bonding that create friction

How thoroughly you clean between uses

For some people, a head lasts 2–3 uses. Others get much more.
It’s really about hygiene and comfort — replace the head when it starts to fray or doesn’t feel as smooth going between your teeth.
That’s why each Glissi kit comes with 20 reusable heads — enough for weeks or even months of cleaner, easier flossing.
