FAQ
Questions about Zentari Arc
Answers for shoppers considering Zentari.
How do I use the Zentari Arc for the first time?
Apply a small amount of toothpaste to the inner silicone surface, place the U-shaped head fully over your upper and lower teeth, press the power button, and hold comfortably in place. The sonic cycle runs for thirty seconds. Remove, spit, and rinse the head under running water.
Is the silicone brush head safe for daily use in my mouth?
Yes. The brush head is constructed from food-grade antibacterial silicone — non-allergenic, BPA-free, and body-safe. The same antibacterial properties that make it mouth-safe also inhibit bacterial buildup on the head between sessions, keeping the tool itself consistently cleaner than a conventional bristle brush.
How does Arc clean teeth without any manual scrubbing?
A high-frequency sonic vibration motor drives rapid micro-movements across all tooth surfaces simultaneously. Because the U-shaped head wraps around every tooth at once — top, bottom, front, and back — the vibration does the work. No technique, no back-and-forth motion required.
How long does the battery last and how do I charge it?
A USB rechargeable lithium cell powers the Arc and typically lasts several days of regular use between charges. Charge via any standard USB cable before the low-battery indicator activates. No proprietary cables needed, making it equally practical at home or while traveling.
Is Arc waterproof? Can I use it in the shower or rinse it fully?
Yes. Arc features a waterproof-sealed electronic assembly, making it safe for full bathroom use. Rinse the silicone head under running water after every session. The sealed body shell is BPA-free ABS, designed to handle the daily moisture conditions of any bathroom routine.
How does Zentari Arc compare to a standard electric toothbrush?
A conventional electric toothbrush still requires manual technique — moving a small head across each zone. Arc's full-arch U-shaped head covers every tooth surface at once in a single thirty-second hands-free session, removing the guesswork entirely. It is a complete system, not just a faster version of what you already own.
What is your return policy if Arc isn't right for me?
Please refer to the current return policy listed at checkout for the most accurate terms. Zentari is positioned as a daily ritual investment, and our customer support team is available to assist if your experience doesn't meet expectations before a return decision is made.
Can I pause or cancel my order or subscription arrangement at any time?
Yes. Any subscription or recurring arrangement can be paused or cancelled at any time — no friction, no penalty. Manage your preferences directly through your Zentari account or reach out to customer support. We believe Arc should earn its place in your routine, not be locked into it.
