ultrasonic denture cleaner

An ultrasonic denture cleaner machine is the best way to keep your false teeth clean, but it should not be the only cleaning tool you use. While studies conducted in 2000 showed how ultrasonic cleaning is the most effective way of removing microscopic debris from dentures, brushing is still the best way to remove the larger particles.

What makes ultrasonic cleaners best for dentures is that a dental plate of false teeth is porous. They can also contain tiny scratches that are smaller than the width of a denture-cleaning brush bristle. These are the places where microorganisms can accumulate and grow. Brushing alone cannot remove them, which is why ultrasonic denture cleaners are the best option to thoroughly clean your dentures.

How An Ultrasonic Dental Cleaner Works

An ultrasonic cleaner is a water bath that incorporates vibrations to remove bacteria. This happens in one of two ways. The tiny bubbles formed by the vibrations pop and create a shock wave that loosens debris on the surface of the dentures. This is followed by the constant movement of liquid being swished around and against the surface.

The popping bubbles combined with the washing away action essentially ‘scrub’ dentures clean. What this means is that without actually touching the surface of the dentures with a brush, the microscopic particles and debris are removed.

How To Use An Ultrasonic Denture Cleaner

An ultrasonic denture cleaner is one of the most effective cleaners for your false teeth. However, for the best possible results, you must use the appliance correctly. We strongly urge you to read and review the instructions that came with your unit to fully familiarize yourself with how it operates.

There are a few simple steps to follow to properly clean dentures. They are as follows:

Step 1 – Brush Your False Teeth

Why should you brush your dentures if you plan on using an ultrasonic cleaner on them? There is a very good reason for brushing with a soft-bristled toothbrush and water. When you do this, you remove large food particles that may not be cleared away ultrasonically. Essentially, you want to make it easy for your cleaner to do the job it was designed to do.

Step 2 – Add The Cleaning Solution to the Ultrasonic Cleaner Tank

The ultrasonic action of the cleaner should be enough to properly clean your dentures. However, to ensure that they do get a thorough cleaning, all you have to do is add either a cleaning solution that is specifically designed for ultrasonic cleaners or just a few drops of the denture cleaning solution that you normally soak them in overnight.

Step 3 – Insert Dentures Into The Cleaning Tank

Gently place your dentures into the tank ensuring they are completely submerged. Note, however, that your dentures should never be placed directly into the ultrasonic cleaning tank. They should be placed in the basket that sits inside the cleaning tank. This prevents possible damage to your dentures should they come in contact with the walls or bottom of the cleaning tank. If your unit does not contain a basket, you will need to purchase one separately.

Step 4 – Turn On The Ultrasonic Cleaner

Close the tank and turn the cleaner on. For units that have timers, it is best to run the cleaning cycle for 5-6 minutes. This provides a complete cleaning of your dentures. If needed, you can also clean your dentures for a second cycle if you are not satisfied with the results from the first cleaning. However, it is mandatory to carefully read the manufacturer’s instructions to understand the maximum number of cycles that are allowed for denture cleaning to prevent overheating and damage to your dentures.

Step 5 – Rinse Then Soak Your False Teeth

The final step to using your ultrasonic cleaner is very important. Once the cleaning cycle has finished, remove your dentures and rinse them off thoroughly under a tap. Follow this by soaking them overnight in a cleaning solution. The added cleaning in the soaking solution will ensure that by morning, your dentures are completely clean and ready for you to put back into your mouth for the day.

Ultrasonic Denture Cleaner Machine Features

In the market for an ultrasonic cleaner for your dentures but not sure what to look for? Here is a quick review of the features to watch for and consider when looking for one of these products to purchase.


A compact ultrasonic cleaner will take up less space on a countertop. However, too small a unit may lack some key features. Make sure the cleaning tank is large enough to accommodate what you intend to clean. Also, lean towards purchasing models that have baskets in the tanks.


An ultrasonic cleaner with a timer will make cleaning much easier in the long run. That is because the timers are usually preset times that you activate with a single touch. Time limits will vary but the longest cleaning cycle should not be so long that you forget you are cleaning something.


It’s best if your ultrasonic cleaner has controls that are easy to read and use. Most models have simple-to-use and understand touch screens or buttons.


It may be handy in your household if you intend to use an ultrasonic cleaner for more than just cleaning dentures. They are effective in cleaning rings and other jewelry and many other small items that are difficult to clean by hand.

After-Sales Support

Another thing to consider is the level of customer support available after you purchase the product. If something goes wrong, you’ll want to be able to fix it quickly. Also, the length of the warranty offered is another thing worth careful consideration.

Ultrasonic Dental Cleaner FAQs

What is an ultrasonic denture cleaner and how does it work?

An ultrasonic denture cleaner has a small tank where dentures are placed. This tank is filled with water or a denture-cleaning solution. When the cleaner is in operation, it sends high-frequency sound waves into the tank. These sound waves essentially vibrate food particles, bacteria, and other debris off the dentures. The cleaning process occurs with microscopic bubbles that are created by the sound waves. A cleaning cycle lasts only a few minutes and most ultrasonic denture cleaners have timers. Once the cycle completes, the unit shuts off automatically.

Does an ultrasonic denture cleaner outperform other denture cleaning methods?

The scrubbing action of tiny bubbles, created by sound waves, can reach places that brushes can’t, making an ultrasonic denture cleaner potentially more effective. It can also remove tough stains that brushing can’t tackle and is more successful at eliminating organisms that can develop into bacteria.

However, don’t consider an ultrasonic denture cleaner as an alternative to manual brushing and regular dental check-ups. The mechanical action of manual brushing removes plaque and maintains the health of gums and teeth. Also, ultrasonic cleaners might not be compatible with all dentures due to their material composition. Therefore, always consult your dental professional before purchasing an ultrasonic denture cleaner.

What precautions need to be taken when using an ultrasonic denture cleaner?

When you use an ultrasonic denture cleaner, take note of the following precautions:

– Read The Instructions: Ensure that you have read the product instructions thoroughly to avoid any potential issues.
– Use the Correct Liquids: You should never use hot water or harsh chemicals in the cleaning tank. They may cause damage to your dentures.
– Avoid Overfilling: When you add the cleaning liquid to the ultrasonic denture cleaner, add only as much as is recommended in the instructions. Don’t overfill.
– Separate Your Dentures: If you have both uppers and lowers, it is recommended that you clean each separately. This reduces the possibility of damage should the ultrasonic cleaning process cause the dentures to scrape against each other.
– Don’t Touch When In Use: When the ultrasonic denture cleaner is engaged in a cleaning cycle, do not touch the unit.
– Personal Safety: It’s a good idea to wear protective eye-wear and gloves when handling the cleaner or cleaning solution, just to be on the safe side.
– Storage When Not In Use: Ensure the cleaner and cleaning solution are stored away from children or pets when not in use.
– Dentures Only: If your ultrasonic denture cleaner is designed for cleaning just dentures, do not use it to clean any other products.

Can an ultrasonic denture cleaner clean all types of dentures?

Not every denture type is appropriate for use with an ultrasonic denture cleaner. Therefore, make sure to check with your dentist to ensure your dentures are safe to use this cleaning process.
Most acrylic dentures are suitable for ultrasonic cleaning. However, it’s not always recommended for use with metal-based dentures, including those with metal clasps. The vibrations from ultrasonic sound waves can potentially damage or loosen metal parts. Also, avoid cleaning damaged dentures with an ultrasonic cleaner as it could lead to more damage.

Do ultrasonic denture cleaners remove stains from dentures?

Using an ultrasonic denture cleaner is effective in removing stains from dentures. Certain foods, beverages, and smoking can stain dentures. Tobacco can cause dentures to yellow and appear dull. The ultrasonic cleaner produces microscopic sound waves that can reach denture surface areas that brushing can’t. However, an ultrasonic cleaner will not be able to remove some stains. For those stains, you will need a professional cleaning from your dentist.

Does it take long to clean dentures with an ultrasonic denture cleaner?

The amount of time required to clean dentures varies based on:

– The type of dentures being cleaned, and
– The amount of buildup to be cleaned.

As for the actual length of time of a cleaning cycle in an ultrasonic denture cleaner, these units have timers that can be set to clean for between 3 and 10 minutes. Do not set dentures to clean for multiple cycles as the sound waves can cause damage if your dentures are overexposed to them. Refer to the instructions that came with your ultrasonic cleaner to be sure.

What features should I look for when choosing an ultrasonic denture cleaner?

There are several features available on ultrasonic denture cleaners. Different models have different features. The following are the main features you should consider:

Cleaning Cycles: Ultrasonic cleaners generally clean dentures in a cleaning cycle that can run from 3 to 10 minutes. Adjustable cleaning cycles allow you to choose a setting that is best for your cleaning needs. Some cleaners have pre-set cycles and others let you set the cycle length.
Ease of Use: Generally, ultrasonic cleaners are not complicated to use.
Frequency/Power: Some ultrasonic denture cleaners come with higher frequency capacity which means they are more powerful than other cleaners. While these may do a better job of cleaning dentures, the higher the frequency means a more expensive product.
Material: When shopping for an ultrasonic cleaner, keep in mind that a unit made with high-quality material will be more durable. But this will also make it a dearer.
Price: There is a good price range available for ultrasonic denture cleaners. Your budget will be the determining factor on which one you will buy, but keep in mind that there are models to fit most budgets.
Timer: To keep dentures from overexposure to high-frequency sound waves, ultrasonic denture cleaners have built-in timers. Some are adjustable. Do not exceed the recommended time to clean your dentures as overexposure can damage dentures.

Before you make a selection on which ultrasonic denture cleaner to buy, consult with your dentist to see which ones are best suited to clean your type of dentures.

Can an ultrasonic denture cleaner damage or warp my dentures?

If you follow the usage instructions, your dentures will not get damaged. However, if you over-expose them to the ultrasonic sound waves, your could damage them. Prolonged exposure to the sound waves could weaken the material your dentures are made from, which may result in warping.

Does an ultrasonic denture cleaner outperform other denture cleaning methods?

An ultrasonic denture cleaner is better than just brushing alone. This is because the tiny bubbles that are created through the high-frequency sound waves can reach places on denture surfaces that brushing cannot. An ultrasonic cleaner can also remove stains that brushing may not. You should still brush your dentures regularly, and continue to make regularly scheduled dental appointments for checkups and cleanings with your dentist.

How often should dentures be cleaned using an ultrasonic denture cleaner?

You should consider using an ultrasonic denture cleaner once or twice a week. However, do not substitute it for regular brushing or dental visits. If you consume certain foods or drinks that may cause staining, you might want to use the ultrasonic cleaner more frequently.

Can an ultrasonic denture cleaner clean all types of dentures?

The material used to make your dentures will determine if you can use an ultrasonic cleaner. For instance, you can clean dentures made from acrylic material with an ultrasonic cleaner. However, metal-based dentures should not. The same applies to dentures with metal clasps. This is because the sound wave vibrations can cause damage to metal parts. Do not attempt to clean dentures that have obvious signs of damage in an ultrasonic cleaner as it may produce further damage.

Why Not Try An Ultrasonic Cleaner For Your Dentures?

There is no doubt that an ultrasonic denture cleaner machine does an effective job of cleaning false teeth. However, they should not be used exclusively. Daily cleaning with a proper denture brush is recommended with nightly soaking of dentures in water or a cleaning solution. But, if you combine this daily routine with the consistent use of an ultrasonic cleaner, you get the best results.
