Best Ultrasonic Denture Cleaners 2021

As a dentist, I think ultrasonic denture cleaners are the best way to keep dental appliances such as complete dentures, night guards and mouth guards hygienic. I also believe that it's important to use one of the best ultrasonic cleaners for your daily cleaning. The good ones are EASILY the most effective way of making sure that your dentures are as clean as possible. And they are endorsed by the American Dental Association.

 An ultrasonic unit is basically a small tub containing a liquid, (usually tap water - but sometimes a special cleaning solution is recommended), which has high-frequency sound waves projected through it. The ultrasound within the liquid causes tiny air bubbles to appear on a microscopic level, and collapse, very quickly, all through the liquid. In short, the ultrasonic energy generates microscopic bubbles

This microscopic "bubbling" cleans the surfaces of anything placed in the tub, like the surface of the dentures. It's a small jacuzzi for your dental appliances and dentures! Studies using an electron microscope prove how effective a true ultrasonic cleaner can be at removing food particles and bacteria.

There are quite a few ultrasonic denture cleaners available. Some are designed specifically for dentures, while most are designed to be general purpose. The only thing special about the "denture-designed" ones is the size and shape of the stainless steel tank.

They are made just big enough to fit a set of dentures into, and tend to be oval in shape. However, I think that some of them are too small, and are not powerful enough to do a decent job. In addition, some manufacturers charge more for them just because they are a "medical device"! BUT they are not specialized medical devices, they are just an ultrasonic cleaning machine.

I have looked at A LOT of ultrasonic cleaners over my 30 years in dentistry, and I have selected JUST THREE units that I think are the best available at the moment. I can recommend them wholeheartedly.

  • iSonic F3900. This is a very compact device, and quite light, so it's great for travel.

The iSonic has a fixed 5-minute auto cycle, then it shuts down. It has a stainless steel tank and a plastic removable basket to put your complete dentures or partial dentures (false teeth) or retainers into. It is mains-powered, so needs to be plugged in to a wall socket.

Some people have reported being surprised by how loud it is, but in reality it's no louder than some sonic toothbrushes such as the Sonicare. The noise is mostly due to the frequency that it operates at, 42,000Hz.

Does this matter? The higher the frequency of the sound waves, the smaller and more penetrating the bubbles. So 42,000Hz is a relatively high frequency for an ultrasonic denture cleaner, and will penetrate into the tiniest spaces.

Here's a link to a YouTube video that gives a demonstration of the iSonic. The presenter is from an anti-snoring device company - it's not me! But I like the presentation.

  • Magnasonic.   This operates at the same frequency as the iSonic above - 42,000Hz. This makes it just as efficient. Like the iSonic, it can operate with plain tap water, or you can use a denture cleaning solution. It has FIVE different cycles, ranging from 90 seconds to 480 seconds. It also has a stainless steel tank, but has a slightly bigger capacity than the iSonic.

I really like the Magnasonic, with it's bigger capacity tub. I think it offers the BEST value for money of all the ultrasonic denture cleaners here. Be sure to check it out at Amazon - I think you'll be impressed! This definitely one of the best denture cleaners available.

  • Generic SonicWave CD2800. At a lower price point than the first two devices, this also operates at 42,000Hz, and has a quality feel about it. The tub is made from stainless steel, and whole thing has a reassuring weight. It is powered by mains electricity, and has a 5-minute cycle with automatic shut-down. The tub has a one pint (16 fl.oz. capacity.)

The cleaning powder that is available with this device can be a little aggressive, however. I recommend using a drop of plain dish washer liquid.

  • Branson 200. Digital ultrasonic cleaner. This is a more expensive option than the others above, at just over $100. However it is also bigger, with a more substantial build quality. The steel tank has thicker walls than the units already mentioned above, and so it will last longer. The ultrasonic waves DO corrode the walls of EVERY cleaner, and eventually the tank will perforate. The Branson B200 will last for years!

Also, the bigger tank size means that the ultrasonic waves can penetrate around your dentures better.

It uses a slightly lower frequency, at 40,000 Hz, but this is a very efficient ultrasonic vibration for cleaning dentures. It works very well at getting all types of dentures clean, and helps to prevent stain building up. It does a great job. This is the Rolls Royce option.

 I think the the best one is definitely the Branson 200. If your budget can stretch to it, and you want the cleanest dentures, the Branson will give the most thorough cleaning, eliminating deep stains and tough stains. It will also last longer than any other cleaners I have seen, because it has the best construction quality. It has the best performance.

How do you clean dentures with an ultrasonic denture cleaner?

First of all, you need to give your dentures a GOOD basic clean, as I describe here in How To Whiten Dentures.

After you have cleaned your dentures with a brush, THEN you can put them in the ultrasonic tub. The dentures should be completely covered with water. It's important that no bits of the denture are sticking out above the water.

Some ultrasonic denture cleaners recommend dissolving one of their cleaning tablets in the water, too. The chemicals in these tablets can help the ultrasonic action to remove bacteria, but if you have scrubbed your dentures beforehand with a brush, I don't think that additional chemicals are really needed.

Now press the button to start the machine, and let it run through its cycle. This usually takes 5 minutes. After the machine has stopped, take your dentures out, rinse them well under the tap, and you're done!

It's important to remember that ultrasonic denture cleaners do not replace the need to scrub your dentures with a brush - they are an extra step in getting your dentures really clean. You have to do both!
