FAQs

Yes! The Orivati ultrasonic cleaner is designed for all types of oral appliances: retainers, night guards, dentures, aligners (Invisalign), and dental trays. The 180ML tank fits most standard sizes.

Yes — and it's a physics problem, not a quality problem. Your toothbrush bristles are approximately 100 times too wide to fit inside the microscopic grooves in your appliance. Cleaning tablets dissolve chemicals into water, but the water just sits on the surface — there's no physical force pushing chemicals into those crevices. The bacteria stay inside the grooves, multiply, and produce the sulfur compounds that cause the smell. Ultrasonic cavitation is the only method that physically reaches these areas.

Yes. Ultrasonic cleaning is completely non-abrasive — it uses water and sound waves, not friction. It's the same method that dental labs use to clean instruments and appliances before sending them to patients. In fact, brushing your appliance with a toothbrush can actually create micro-scratches where bacteria embed even deeper.

No. The 42kHz ultrasonic frequency is specifically calibrated to be safe for oral appliance materials including acrylic, Essix plastic, and thermoplastic. The cleaning process is gentle enough for daily use and has been used in dental offices for decades without damaging appliances.

The device features a simple dual-speed timer with 2 modes: a 5-minute Quick Clean and a 10-minute Deep Clean. For routine daily maintenance of retainers and aligners, simply click the button once for the 5-minute cycle. For heavy night guards, dentures, or intensive biofilm removal, click twice for the 10-minute Deep Clean.

Yes! The Orivati ultrasonic cleaner uses plain tap water only. No cleaning tablets, no special solutions, no chemicals required. The 42kHz ultrasonic vibrations and UV-C light do all the work. This also means no chemical residue on your appliance — just clean, rinsed dental equipment.

Mouthwash has the same limitation as cleaning tablets — it cannot physically reach the microscopic grooves where bacteria live. It only touches the surfaces the liquid can reach. Ultrasonic cavitation creates millions of microscopic bubbles that reach into every crevice through physical force, extracting bacteria that mouthwash (or any liquid-only method) cannot touch.

We offer a 30-day money-back guarantee. If you're not satisfied with the cleaning results, return it for a full refund — no questions asked. We also recommend watching the 'brown water' phenomenon during your first few uses — seeing the extracted debris in the water is the most convincing proof that the cleaning is working.

Yes! The 180ML stainless steel tank is wide and deep enough to comfortably fit clear aligners, plastic/wire retainers, thick night guards, and even upper and lower dentures at the same time. One machine for endless cleaning possibilities.

No! The Orivati uses 42kHz ultrasonic cavitation and regular tap water to physically pull debris out of the grooves. It helps clean oral appliances more thoroughly than tablets alone, saving you $60-$100 a year on chemical cleaners that only mask the smell.

Many appliances look clean to the naked eye but still harbor bacteria in microscopic pores (causing that sour "wet dog" smell). We challenge you to the "Brown Water Test": soak it in your tablet, then run it in the Orivati. You'll be shocked at the murky water left behind!

No, it's actually safer than brushing! Manual brushing creates micro-scratches in the plastic where bacteria hide and embed deeper. Ultrasonic cleaning is entirely non-abrasive—it uses water and sound waves, extending the life of your expensive dental appliance.

Super easy! Just unplug the device, empty the water from the 304 stainless steel tank, and wipe it dry with a clean cloth or paper towel. No hidden crevices or complex maintenance required.

Not at all. It operates with a quiet, soft hum (similar to a low vibration) that won't wake up your partner or disrupt your household morning routine.

Yes! While designed primarily for oral appliances, the 42kHz ultrasonic waves safely and effectively clean manual toothbrush heads, pacifiers, and waterproof jewelry like diamond rings and metal watch bands.

Absolutely! We offer a 30-Day Smell-Test Guarantee. If your appliance doesn't pass the smell test or you don't see the proof in the water, return it for a full refund—every penny back. No questions asked, no hassle. We're that confident.
