Trusted technology
Decades of dental heritage, adapted for home
Ultrasonic cleaning has been part of dental practice for generations — the quiet workhorse behind spotless instruments. The Sonic takes that clinical principle and reworks it for the shape, scale and materials of the appliances you wear every day.
Rather than relying on abrasion or harsh chemistry, it uses sound energy passing through water. That makes it inherently gentle: it works around the delicate contours of a retainer or aligner without touching them, so cleaning never comes at the cost of the fit you rely on.
What can The Sonic clean?
If it goes in your mouth and comes back out, it belongs in the tank. The Sonic is designed for the full range of oral appliances.
Why no UV light?
UV can only treat surfaces it can actually reach. In cloudy water, shadowed grooves or under a layer of biofilm, its energy never lands. Ultrasonic cleaning is physical, not optical — cavitation dislodges build-up from every surface at once, including the crevices UV never sees.

Why we built The Sonic
Cleaning an oral appliance has always been an awkward compromise. Brushing scratches the surfaces you rely on. Soaking in solution takes hours and still leaves cloudiness behind. Most people simply give up and rinse — and wear something far from clean.
We started Nuvora because that felt like a solved problem hiding in plain sight. Dental practices had used ultrasonic cleaning for decades; it had never been properly designed for the home. So we engineered a device around the real appliances people wear, tested it against the build-up they actually deal with, and stripped away everything that wasn't the clean itself.
The Sonic is the result: one button, five minutes, no compromise. We're grateful to the dentists and hygienists who guided us, and to the hundreds of thousands of customers who now trust it as part of their daily routine.
— The Nuvora team
Don't take our word for it. Dentists trust us.
"I recommend ultrasonic cleaning to every retainer patient now. It reaches the interproximal spaces a brush simply can't, and it's gentle enough that I'm not worried about long-term fit."
"Patients ask me how to keep clear aligners from going yellow. This is the honest answer. The cavitation clean is consistent in a way that home brushing never is."
"For my denture-wearing patients this has been genuinely useful. It removes the film that leads to odour and irritation, without the abrasion that wears acrylic down over time."
"The science here isn't new — it's what we use in practice. What's changed is that a patient can now get a comparable clean at home in five minutes. That's a meaningful difference in compliance."
"I fit a lot of night guards, and the ones that come back looking cared for tend to belong to Sonic users. It's a simple habit that protects the investment."
"Non-abrasive is the part that matters to me clinically. Micro-scratches trap bacteria and dull clear appliances. This avoids that entirely, which is why I'm comfortable recommending it."
"My hygiene team suggests it to anyone struggling with appliance odour. The feedback has been consistently positive — people actually keep up with it because it's effortless."
Got questions? We've got answers.
Tablets rely on chemistry alone and need a soak to work. They can lift some staining, but they don't physically dislodge biofilm from grooves and edges. Ultrasonic cleaning does — and pairs well with the occasional tablet for a deeper refresh.
Brushing creates fine micro-scratches on aligners, retainers and dentures. Those scratches dull clear appliances and give bacteria more surface to cling to. The Sonic never touches the appliance, so there's nothing to scratch.
No. The clean is non-abrasive — it's sound energy moving through water, not friction. It works around the delicate structure of your appliance rather than against it, which is why dentists are comfortable recommending it.
Yes. Clear trays are exactly what it was designed for. A five-minute cycle keeps them transparent and removes the film that causes cloudiness and odour.
Yes — including bonded and Hawley-style retainers with metal components. Ultrasonic cleaning is safe for both the acrylic and the wire.
Absolutely. Night guards trap saliva and bacteria overnight; a daily cycle removes the build-up that causes smell and keeps the guard hygienic.
Once a day is ideal — most people run a cycle each morning while they get ready. A quick daily clean prevents build-up far better than an occasional deep clean.
Empty it after each use and wipe it dry. Every week or so, run a short cycle with plain water and a drop of mild soap, then rinse. The stainless-steel tank resists staining and scale.
The Sonic comfortably fits one appliance, or a small pair such as upper and lower retainers. For larger loads or two full aligner sets, The Sonic Pro's bigger tank is the better choice.
Yes. While it's built for oral appliances, the same cavitation clean works beautifully on rings, earrings and other small hard items. Avoid soft or porous stones such as pearls or opals.

What our customers say
Priya
My Invisalign trays used to go cloudy within a fortnight. Five minutes in this and they're clear again. Wish I'd bought it at the start of treatment.
Tom
I grind at night and my guard always smelled no matter how much I brushed it. That's completely gone now. Genuinely didn't expect such a difference.
Margaret
I've worn dentures for years and this is the first thing that's made cleaning them feel easy. No fiddly brushing, no harsh tablets. It just works.
Daniel
Cleans my retainer beautifully, including the metal wire which I was worried about. Only wish the tank were slightly bigger — otherwise faultless.
Aisha
Sits neatly on the bathroom shelf and looks lovely in sage. But it's the clean that sold me — my night guard hasn't looked this good since it was new.
Greg
My orthodontist mentioned ultrasonic cleaning so I gave this a go. The retainers feel properly clean now, not just rinsed. Part of my morning routine.
