A rechargeable U-shaped sonic toothbrush that cleans all your teeth at once with antibacterial food-grade silicone — no scrubbing, no thinking, just thirty seconds.
30 Day Money-Back Guarantee
When a full-arch sonic head replaces guesswork, the numbers show exactly what changes.
Every component inside Arc is chosen to make a thorough clean automatic — no technique, no guesswork, no missed spots.
The only full-arch head that wraps every surface at once. Non-allergenic and BPA-free, this silicone construction actively resists bacterial buildup between sessions so the tool cleaning your teeth stays cleaner than a conventional bristle brush.
Sonic micro-movements do the scrubbing so you never have to. Rapid vibrations propagate across all tooth surfaces simultaneously, dislodging plaque thoroughly in thirty seconds without any manual pressure or arm fatigue.
Long-lasting power with no proprietary cables to track down. A high-capacity lithium cell keeps Arc charged and ready whether you're at home or traveling, using a standard USB connection that fits any kit.
Built to live in the bathroom and rinse clean after every use. A fully sealed interior protects all electronics from water exposure, so rinsing Arc under the tap is all it takes to keep the device hygienic between brushing sessions.

“works in the dark, which is all I needed I brush my teeth at 5am without turning on the light and this just runs itself. Zentari Arc is the first thing in my routine that actually asks nothing of me.”
Jessica M.From every missed surface to a faster morning routine, here's what makes Arc different.
Arc combines high-frequency sonic vibration with antibacterial silicone to give you a complete, effortless clean every single time — no technique required.
Every tooth, every time
Sonic vibration does the work
A brush head that stays cleaner
Thirty seconds, genuinely done
Arc is built to turn a rushed daily habit into a effortless, complete clean — here is how your routine evolves from the very first use.
Every tooth. Every surface. Thirty seconds. No technique required.
Every tooth. Every surface. Thirty seconds. No technique required.
The food-grade silicone head resists bacterial growth between sessions on its own. Conventional bristle brushes can't say the same — they trap bacteria and degrade in ways silicone simply doesn't.
You've been brushing the same way your whole life and still leaving the same spots untouched. Arc removes technique from the equation entirely — bite down, let it run, and you're done.
Arc's brush head is BPA-free, non-allergenic food-grade silicone — the same category of material used in medical and food-contact applications, and a meaningful step up from the nylon bristles on every brush you've owned before.
Arc's full-arch U-shaped head wraps around your upper and lower teeth simultaneously — front, back, and in between — so the spots your regular brush always misses finally get cleaned every single time.
The sonic motor does the work so you don't have to. No two-minute timer, no scrubbing technique, no arm fatigue — just a thorough clean that fits into any morning without a second thought.

Full-Arch Clean
30-Second Routine
Hands-Free Design
Zentari Arc is a hands-free sonic toothbrush built around a U-shaped food-grade silicone head that wraps around every tooth at once — top, bottom, front, and back. High-frequency sonic vibration does the cleaning in thirty seconds flat. No technique required. No spots missed. Just a genuinely complete clean, every single morning.
Most people miss the same spots every day — and it's not their fault. A conventional brush only cleans where you move it, which means perfect technique is the price of a thorough clean. Arc removes that variable entirely. Its full-arch silicone head reaches every surface simultaneously, so the quality of your clean no longer depends on how awake you are at 7am.
Cleans all tooth surfaces in a single thirty-second session. Eliminates technique-dependent gaps that conventional brushes leave behind. Food-grade silicone head resists bacterial growth between uses. BPA-free and non-allergenic construction. USB rechargeable and travel-ready. No arm fatigue, no timer anxiety — just a calm, consistent clean.
Place the Arc mouthpiece over your teeth, press the button, and bite down gently for thirty seconds. That's it. Use morning and night to replace your existing brushing routine entirely. Most customers notice cleaner-feeling teeth from the very first session.
Every Zentari Arc is backed by a 30-day money-back guarantee. If you're not completely satisfied with your clean, contact us and we'll make it right — no questions asked.

Compared to my old Oral-B Smart series, the hands-free design actually keeps pressure consistent around my crown. In my experience, two weeks in and my hygienist noticed less buildup near the gumline.
The buzzing is louder than I expected at 7am. but honestly when you're half-asleep holding a toothbrush you don't even care, it just works.
So i have ADHD and my dentist has been on my case about the two minute thing forever (i always bail at like 45 seconds). The Zentari Arc just does it for you and honestly i had nothing else to do but stand there.
