Ultrasonic waves
The tank vibrates 42,000 times a second - far above hearing. The water cannot follow a movement that fast, so it starts to pull apart.
Ultrasonic Denture & Night Guard Cleaner
Lifts the film a brush leaves behind - in five minutes, hands off. One button, then you walk away.
Ultrasonic cleaning is what a dental practice uses on instruments. This is the same principle, sized for a bathroom counter and run off one button.
- Removes the residue, stains and buildup a brush only pushes around
- Keeps acrylic and clear plastic looking clear instead of cloudy
- Takes out the smell and the taste that are back again by lunchtime
- Five minutes, hands off - fill it, drop the appliance in, press once
What it actually does
- Non-abrasive removal of grime, stains and buildup
- Gentle on acrylic, soft guard material and metal clasps alike
- Reaches into the crevices and around the wires a brush cannot get to
- Extends the life of an appliance that costs hundreds to replace

The science behind it
The science behind it
The tank runs at 42,000Hz - forty-two thousand pressure cycles a second, far above anything you can hear. That vibration pulls the water apart into millions of microscopic bubbles, and each one collapses again almost instantly. Every collapse releases a tiny amount of energy right at the surface it is touching, and that is what lifts deposits off.
Because the bubbles go wherever the water goes, the whole appliance is cleaned at once - the fitting surface, the inside of every tooth, the grooves around a clasp. Nothing abrasive is involved, so nothing scratches. Ultrasonic baths have been standard equipment in dental practices for decades; this is the same method on a smaller tank.
What it can clean
Full and partial dentures, night guards and bite guards, retainers including Hawley retainers with metal wires, clear aligners, sports mouth guards, sleep apnoea devices and toothbrush heads.
Acrylic, soft guard material, clear thermoplastic and stainless steel components are all fine - there is no brushing and no scrubbing, so there is nothing to wear a surface down. If you are unsure about a particular appliance, ask whoever fitted it before the first clean.
Why there is no UV lamp in it
Because UV light is stopped by the very thing you are trying to clean. It only works on a surface it can reach, and it cannot reach through cloudy water, through a film of plaque, or into the fitting surface of a denture where the appliance sits against itself.
Ultrasonic cavitation works the other way round - it goes wherever water goes and it removes the deposit physically instead of shining light at it. That is the whole reason this tank has no lamp in it.
Shipping and warranty
Shipping is tracked, and the cost is calculated at checkout against your address before you pay - nothing is added afterwards.
The unit carries a one-year warranty. If it stops running inside that year, we replace it. Separately from the warranty, you have 30 days to send it back for a refund if it simply is not for you.

How it works
Just add water. Here is what the water is doing.
Cavitation
Those gaps become millions of microscopic bubbles. Each one collapses almost as soon as it forms, releasing its energy exactly where it sits.
The deposit lifts
Collapsing against the appliance, they work loose the film, the stain and the buildup in the crevices - without anything solid touching it.
A deep clean at the touch of a button.
Ultrasonic cleaning does the part of the job a brush and a tablet between them cannot do.
Your problem
A denture or guard that has gone cloudy, tastes of yesterday and never feels properly clean
The method
42,000Hz cavitation reaching every surface at once, including the ones you cannot brush
Your result
An appliance that comes out clear, smells of nothing, and feels like it did at the fitting

Nothing Touches ItBut Water
The part a brush was never going to reach
Same appliance, same light, five minutes apart. Nothing is polished, whitened or retouched - the deposit is simply gone.
BeforeAfter
A full upper denture
Coffee and tea staining across the palate and a brown line where the acrylic meets the teeth. Same denture after one cycle - the same tooth wear, the same fine scratches, none of the film.
BeforeAfter
A clear night guard
Eighteen months of cloudiness and a chalky white bloom in the molar wells. After: clear enough to read the tooth impressions through it again.
BeforeAfter
A Hawley retainer
White calcified buildup collected around the wire and in the acrylic seam - the exact place a toothbrush skates over. The wire bends are identical afterwards. Only the deposit changed.
Got questions? We've got answers
What is wrong with just using a cleaning tablet?
Nothing, as far as it goes - but a tablet only treats what it can touch. It works on the surface and it does not shift what has already worked its way into the crevices and the fitting surface. It is toothpaste with no toothbrush. Used together they work well: run a tablet in the tank and the cavitation carries it into the places it could not reach on its own.
Can I not just scrub it with a toothbrush?
A toothbrush is abrasive, and appliance acrylic is much softer than enamel. Every scrub leaves fine scratches, and those scratches are grooves that hold more buildup than the smooth surface did - which is why a well-brushed denture still goes cloudy over a couple of years. Bristles also cannot get around a clasp or into the fitting surface.
Will it damage my denture or guard?
No. Nothing solid touches the appliance at any point - it sits in water while microscopic bubbles collapse against it. There is no heat cycle, no scrubbing and no harsh chemistry. Acrylic, soft night-guard material, clear thermoplastic and metal clasps have all been cleaned this way in dental practices for decades.
Does it work on full and partial dentures?
Yes - this is what it is best at. A denture has the largest hidden surface of any appliance: the whole palate side sits against your gum all day and never sees a brush properly. Partials with metal frameworks and clasps are fine too, and the wire junctions are exactly where cavitation earns its keep.
Does it work on night guards and bite guards?
Yes. Both the hard and the soft kinds. Guards develop a chalky bloom in the tooth wells within a few months because they spend eight hours a night in a warm, closed mouth, and that bloom is what a brush cannot lift out of the wells without scratching them.
Does it work on retainers and clear aligners?
Yes - clear retainers, Hawley retainers with metal wires, and clear aligner trays. Aligner trays in particular go foggy fast because they are worn 22 hours a day, and foggy trays are visible.
How often should I run it?
Once a day suits most people, usually in the morning while you get ready. There is no wear cost to running it more often. If whoever fitted your appliance gave you a cleaning routine, keep to theirs.
How do I clean the unit itself?
Tip the water out after each cycle and wipe the tank with a cloth - the loosened deposit is now in the water, not on the appliance, so getting rid of it matters. A mild soap and water is fine for the tank. Do not put it in a dishwasher.
Can I clean two at once?
Yes. Two appliances fit in the tank comfortably - a pair of aligner trays, or an upper and a lower. Give them room rather than stacking them, so the water can reach every surface.
Will it clean jewellery?
It is not designed or tested for it, so we make no promise. Ultrasonic baths have been used on metal jewellery by trade for a long time and the principle is identical - but soft or set stones can be loosened by cavitation, so that is at your own risk and not what you are buying it for.

What people say once they have seen the water
★★★★★
Twenty-two years of soaking tablets, and this got more off in five minutes
I have worn a full upper since I was fifty-one and I have soaked it in tablets every single night of that. I genuinely thought it was clean. The first cycle in this turned the water grey. The palate side is a different colour now - lighter, the way it looked when it was new. I have not stopped feeling slightly embarrassed about it.

My night guard stopped tasting like a night guard
The taste in the morning was the thing that got me. I would rinse it, brush it, and by the next night it was back. Turns out the taste was living in the tooth wells where the brush never actually went. Two weeks in and there is no taste at all. My wife says there is no smell either, which she had apparently been too polite to mention for a year.

The cloudiness came off my retainer, not just the surface bits
Mine is a Hawley with the wire across the front and the buildup collects right where the wire goes into the acrylic. I had scrubbed at it with a soft brush for months and only ever got the loose bits. This lifted the white stuff out of the seam. I ran it twice the first day because I did not believe the first one.

It sits on the counter, so it actually gets used
The tablets lived in a cupboard and I used them when I remembered, which was not often. This lives next to the tap. I fill it while the kettle boils, press it, and it is done before the tea is. That is the whole reason it works for me - it is not a better routine, it is one I actually do.

Does exactly what it says. Louder than I expected.
No complaints about the cleaning - my partial comes out properly clean around the clasps now, which is the bit I could never manage. Only note is that it does make a high buzzing sound for the five minutes. Not loud enough to leave the room, but it is not silent, and I would rather someone had told me than not.
