Using an ultrasonic denture cleaner is by far the most effective way of cleaning your false teeth. These devices have the ability to scrub the surface of the dentures at a microscopic level.

At Dental Dorks, we recommend using an ultrasonic cleaner as a supplement, rather than a replacement, of the toothbrush. These machines are extremely efficient at removing microorganisms from places where the bristles cannot reach. But, brushing remains the best way to remove larger and visible particles.

iSonic F3900 Ultrasonic Cleaner for Dentures

iSonic-F3900-Ultrasonic-CleanerSpeaking plainly, iSonic is the Waterpik of denture cleaners. It is the manufacturer that has been able to take over the market by designing and creating innovative and helpful products.

The F3900 is by far iSonic’s best ultrasonic dental cleaner. It is highly effective, functional, compact, easy to use, and above all, fairly priced.

When it comes to power, this device either tops all others or equals their output. At 42,000 Hz, the vibrations that are being created are certainly past the sonic waves, and into the land of ultrasonic sound. Operating at 110V 20W, this is by far the smallest and most powerful ultrasonic cleaner for dentures, mouth guards and night guards available in North America.

When I say “small” I really mean “compact”. This unit measures 7”x4.5”x4.5” (inches), which makes it easy to store.

It is often hard to detect any motion when the unit is turned on. If you look hard enough, you might see a slight standing wave pattern running on the surface of the water. Such high frequency of vibrations escapes the human capability of sight-comprehension. If the unit is vibrating, this means that it is working. No need to stick your finger in it.

Unlike competing brands, this is not battery operated. This unit is AC powered, and it begins generating cavitations in the fluid within milliseconds. The tiny air bubbles start to do their job immediately by effectively vacuuming debris that has been stuck in the dentures.

The iSonic F3900 is one of few units out there that are specifically designed as denture cleaners. So, we would not recommend cleaning anything else, such as jewelry, in it. Stick to false teeth, mouth and night guards.

Magnasonic Ultrasonic Cleaner

Magnasonic-Ultrasonic-CleanerThe name of this item always reminds me of Megatron and the rest of the transformers. But, at the end of the day, the MGUC500 is no bigger than a regular two slice toaster.

Magnasonic is easily considered one of the best ultrasonic cleaner manufacturers on the market. Their products are solid, made in compact sizes, and quite simple to operate.

The device comes with a small basket that can be used to place your dentures in it. Originally meant for jewelry and other ornaments, this device will do a great job polishing your false teeth.

The digital timer on the machine gives the user a choice of 5 different cycles: 90, 180, 280, 380 or 480 seconds. For most dentures, 280 seconds are enough. But, that depends on how often you clean them, and in what condition they are. Once finished, an automatic timer turns the machine off.

It is not too loud, and not too quiet. On the noise level, this ultrasonic device measures pretty much like any other that we have reviewed above. Maybe only the B2000 is a tiny bit louder when compared. But, it is also more powerful than the MGUC500.

The ultrasonic waves of this unit are in the lower range of 42,000 Hz, like most of its competitors. This, however, is more than enough to generate enough power for the 600ml tank to clean any and all dentures.

This is perhaps the most popular and well-reviewed item on the market right now. Despite some serious competition from brands like iSonic and DBTech, Magnasonic have managed to stay on top of their game.

DTMCare Ultrasonic Dental Cleaner

DTMCare-Ultrasonic-Dental-CleanerUsing ultrasonic speed and ultraviolet light, the DTMCare is specifically designed to clean up and sanitize dental equipment and appliances.

The ultrasonic vibrations of this unit reach up to 18,000 movements per minute. Making it one of thhigh-frequencycy dental cleaners on the market. People have reported successfully cleaning jewelry, but we would still not recommend using the same device for dentures and other objects.

All DTMCare models come with a built-in energy saving function. The device will automatically turn off after 20 minutes of use, in order to preserve energy and batter life. In addition, the power will automatically turn off if the lid is open. This is done mostly to protect your eyes from the harmful UV light that is designed to further sterilize your dentures.

Even though the unit is efficiently designed, it is not good-looking by any means of the word. It uses magnets in order to assure proper seal and tight closure, but it is a squarely, white and yellow looking shoe box. Not something I would display in my guest bathroom for everyone to see.

Being surprisingly small (5”x5.2”x4.2”), this unit can only hold one object at a time. This is not bad, because you normally want to be cleaning up one denture at a time anyways.

Looks aside, the unit comes with one year warranty and it will do a good job of cleaning dentures. It is made in Taiwan, despite all parts being manufactured in Japan. We have not teste the warranty, since the unit is working just fine, so we cannot say if the manufacturing origin would play a negative role on the warranty.

Nevertheless, this is an FDA approved and CE Medical approvethe d device. So, you can buy with confidence knowing that there is accountability behind this product.

Branson Model B200 Ultrasonic Cleaner

Branson-Model-B200-Ultrasonic-CleanerBranson’s forte is not nested in the dental industry, per se. However, they are a rather large manufacturer that is known for producing industrial cleaning and electronics products. Having said that, we are in luck because they have a small B200 ultrasonic cleaner model that can be an excellent solution for your denture cleaning needs.

Branson is not an innovator, but they are very good at following up with current technologies and improving them. In my books, this is almost as good as innovating new technologies.

The B200 model operates at 120V and 50-60 KHz. This makes it by far the most powerful cleaner for its size. But, it also makes it twice as expensive as any other ultrasonic cleaner in that size. Most of its competitors are in the 40-42 KHz, and as such, are priced way lower. So, if you have some extra money to splash, and you want to opt in for some raw power, B200 is the way to go.

There is a built in 5 minute timer, which is a good idea, given how powerful this cleaner is. You do not want the false teeth falling out of their place during the high frequency vibrations. Just kidding, this is not possible, regardless of the raw power that this unit produces.

Like other products in this spectrum, Branson offers a 1 year full warranty. So, you get a replacement in case the one you get breaks down, or does not work upon arrival.

Additionally, the B200 is FDA, FCC, CE and CSA approved. If you have any other acronyms in mind, you can run them by us, and we will do our due diligence to check if they are applicable!

Even though this particular model does not have a large tank capacity, it is kind of chunky. It weighs almost 3 lbs and it is 8.7” wide.

DBTech Digital Ultrasonic Dental Cleaner

DBTech-Digital-Ultrasonic-Dental-CleanerOriginally designed for cleaning jewellery, watches, lenses, retainers and other goods that you can win at a home poker game, this device will do a fine job at cleaning your dentures.

The tank has a 17 ounce capacity and it can be filled up with tap water. The quiet, but powerful motor, will create up to 42,000 ultrasonic energy waves per second and leave your dentures spotless in the meantime. The device also includes a basket that you can use when cleaning your dentures. Even though, it is not necessary. It is still nice that it has been included. The more, the merrier!

Unlike other devices, this one works by plugging it directly into the electric outlet. So, there is no additional expenses for batteries. It also allows the unit to maintain the same power throughout the cleaning process.

There are 5 individual cycles for you to play around with including an auto shut off function to prevent overuse. After all, there is no need to blind anyone with the shine of your false teeth.

Unlike other brands, DBTech include a cleaning solution in the form of a tablet that comes with this model when purchased. It is non-toxic and it can be used with regular tap water in order to further enhance the cleaning process. It is environmentally friendly, safe and it has absolutely no odor.

In addition, DBTech are kind enough to include a 100% cotton flannel, in case you wanted to further polish your dentures. Even though, we would recommend letting them dry. You do not want cotton stuck between your teeth!

This model is a great alternative to brushing your dentures. It is priced very competitively and it can be yours for less than $40 in most cases.

Hornady Lock N Load Sonic Cleaner II

Hornady-Lock-N-Load-Sonic-cleaner-IINot to be mistaken with previous versions, this is the Lock N Load II model. Bigger, better, and faster.

Despite that the name suggests a sonic cleaner, this is indeed an ultrasonic device.

This Hornady model is great for cleaning more than one piece of dentures at a time. Unlike the other models reviewed here, this is a slightly bigger device. It holds a 2.2l tank, and it can comfortably take 2 pieces of false teeth at a time.

The internal size of the cleaning tank is 7.25”x6”x3”, which makes it twice as big as the MGUC500, for example. According to some reviews, the tank is so big, you can fit an entire gun (Glock) in it. I do not know if this is impressing, or if the amount of cleaning care that people dedicate to their guns is actually scary.

Since this is a bigger cleaner, it has a “bigger” timer. Or, should I say, a timer that allows larger intervals of time for cleaning your dentures and other items. You can select cycles starting from 5 minutes all the way up to 30 minutes. We, however, would not recommend washing your false teeth for more than 5-6 minutes in this machine. This should be plenty of time to get them well cleaned and polished.

iSonic D3800A

iSonic-3800AThis is another small ultrasonic dental cleaner by iSonic that can be yours for less than $35 or so. Available in white, silver or pink, this unit gives you a proper choice of colors. What it does not give you, however, is a large tank capacity.

Sitting at around 600ml, this unit measures well against competitors in the same price range. But, it falls well behind units, such as the Lock N Load cleaner. Which is fine, because you do not need much space for your dentures. This tank is plenty enough for a standard sized denture or braces.

The D3800A operates at an ultrasonic frequency of 42,000 Hz, 110V, and 25W. This places it shoulder to shoulder with the iSonic F3900 unit that we reviewed above. In other words, it is just as powerful, and the two units are practically identical. The only exception is that the D3800A is a bit smaller (5.7”x5.7”x8.3”).

In case you were wondering, yes, there is a digital watch. There are also 5 different cycling settings: 90, 180, 280, 380, and 480 seconds. This is not revolutionary technology, but combined with the automatic shut off function, it is pretty useless. No ultrasonic denture cleaner should be manufactured without this simple tech in place.

This is a good all-around choice for denture cleaning. It has positive reviews on forums and e-commerce websites. It is well-priced, and it is powerful enough to do the job. If not, it has a 1-year warranty that allows you to substitute it.

First and foremost, if you have dentures (or false teeth), you are not off the hook when it comes to brushing. Actually, it is quite the opposite. It is absolutely crucial for you to clean your dentures every day in order to assure proper hygiene and lower the risk of various mouth diseases.

What is an ultrasonic denture cleaner?

Cleaners that use ultrasonic vibrations are by far the best way to clean any kind of dental appliances and equipment at home. We do not just say this, there are actual empirical studies that have already proven this.

Ultrasonic dental cleaners are rather simple looking devices with water tanks. The way they work, is by creating ultrasonic vibrations with the help of a high frequency transducer. You are most likely thinking about Jacuzzis right now, and you are not too far.

The intense ultrasonic agitation of the water creates an effect known as cavitation. In simple terms, the ultrasonic shockwaves create tiny bubbles which are able to eliminate microscopic debris from the denture’s hidden surface areas.

How to use and ultrasonic denture cleaner?


First, and foremost, make sure your false teeth are thoroughly brushed. This is still the best way to get rid of large and visible debris.

Fill the tank of the device with water. There is no need to get fancy here, tap water will do the work just fine. In addition, some manufacturers include chemical solutions in the form of tablets. All you have to do, is place the tablet in the water tank, and wait for it to dissolve.

  • Soap could be a cheaper alternative to those tablets. Especially, if the model you have purchased does not come with a chemical solution.

Next, you need to place your dentures in the already filled with water tank, and make sure that they are fully submerged.

Based on the brand and model, select a cycle, turn the device on, and let it run. In most cas,es 5 minutes are enough to clean false teeth.

Once the cycle has ran its course, turn off the unit. Also, it is a good idea to rinse the dentures truly, especially if you opted in to use the chemical tablets.

Word of caution: In theory, the continuous use of an ultrasonic device to clean two dentures at the same time, could result in their wear and tear. That is, if both the lower and upper dentures are simultaneously cleaned. The fast vibrations can cause the two parts to rub against each-other, therefore, causing them to slowly deteriorate.

However, the wear that will be experienced over time is quite minor. To completely avoid this possibility, clean each denture separately.

Sonic vs Ultrasonic

Beware when you are choosing a denture cleaning device, because there is a difference between sonic and ultrasonic units. The former vibrate at a lower speed. This means that the agitation that they create in the water is not as powerful, and it will not result in the same cleaning. Such devices should not really carry the “sonic” name. They should simply be referred to as “fluid agitators”, since this is their main function.

Should you use an ultrasonic denture cleaner?

Getting older is one certainty in life that we cannot escape. Deteriorating oral health is one side effect of the process of aging that we also cannot escape. As such, taking care of your teeth, or false teeth, becomes even more important with age.

While brushing should remain the leading component of anyone’s oral hygiene, it is simply not enough for denture wearers. Recent study has found a positive correlation between higher levels of lactobacilli and yeast in older subjects. These can lead not only to bad breath, but tooth decay as well.

One commonality between dentures and real teeth is that they both have tiny pores. These cracks are invisible to the eye, and while denture brushes are good, their bristles are simply incapable of cleaning these cracks. Only liquid is adept enough to get in those tiny pores and assure all microbes and debris are completely removed.

What about tablet cleaners?

There certainly is an abundance of tablet cleaners on the market. There is one study done in 2016 that found them particularly helpful for denture cleaning. The study proceed to compare brushing, ultrasonic cleaners and tablets in order to determine which one performs best.

Brushing and ultrasonic denture cleaners were found to be less effective when compared to tablet solutions. It was found that when soaked for 12 hours, tablets were able to remove more harmful bacteria from the dentures. While this is entirely possible, ultrasonic denture cleaners on average only take 5 minutes to complete the process.

This of course is not the only study. In another scientific experiment that involved 3 groups, researchers determined that tablets and ultrasonic devices are equally superior to brushing.

In order to get a complete picture, it is probably best to look at both studies. In this sense, each method can be viewed as complimentary to the other. So, in all fairness, tablet cleaners surely have their place when it comes to maintaining your false teeth. The question is, do you have 12 hours to soak your teeth every night?

Concluding thoughts

At the end of the day, ultrasonic denture cleaners can qualify as quite useful. They save time, offer denture cleaning at a microscopic level, while usually costing less than $40.

The best units on the market are more or less the same. They offer similar vibrations speed, similar 1 year warranties, and similar water tank capacities. Some differ in size, color, and tend to offer a variety of cycling settings. But, automatic timers and removable baskets are not exactly innovation.

Each unit that we have reviewed above is guaranteed to work well.
