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 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

One more important consideration is the level of customer support available after you purchase the product. Should something go wrong, you will want to be able to resolve the issue quickly. Also, the length of the warranty offered is another item worth careful consideration.

Ultrasonic Dental Cleaner FAQs

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

An ultrasonic denture cleaner is a device that uses high-frequency sound waves to clean false teeth and other dental appliances. The device comes with a small tank that is filled with a cleaning solution.
A transducer emits ultrasonic waves into the tank where you will have placed your dentures. The ultrasonic waves essentially shake off tiny particles of food and debris from the surfaces of your dentures. They do this by producing millions of tiny, microscopic bubbles that “scrub” anything that is in the cleaning solution. The unit can be programmed to send these waves for a certain number of minutes. Once complete, most units automatically shut off.

Is an ultrasonic denture cleaner more effective than other methods of cleaning dentures?

An ultrasonic cleaner can be more effective than other cleaning methods. Scrubbing action of the tiny bubbles created by sound waves is more thorough than brushing alone as the bubbles can get into places brushes cannot. Also, an ultrasonic denture cleaner can remove tough stains that brushing cannot. It is also more effective in removing organisms that can develop into bacteria.
However, an ultrasonic denture cleaner should not be used as an alternative to manual brushing and regular dental check-ups. The mechanical action of manually brushing removes plaque and keeps gums and teeth healthy. Plus, not all dentures are compatible with ultrasonic cleaners because of the material they are made from. To be sure, consult with your dental professional before investing in an ultrasonic denture cleaner.

How often should I use an ultrasonic denture cleaner to keep my dentures clean?

A few factors must be considered in determining the frequency of cleaning dentures with an ultrasonic cleaner. These factors should include the type of denture, how often they are used, and the level of buildup and staining on the dentures. Generally speaking, using an ultrasonic cleaner once or twice a week will help you to maintain good denture hygiene. If you consume foods and liquids that stain dentures quickly, you may want to use the ultrasonic cleaner more frequently.

Are there any special precautions I should take when using an ultrasonic denture cleaner?

There are a few precautions you should take when using an ultrasonic denture cleaner. They include:
–       Read the instructions that came with the unit before using it and follow them closely.
–       Do not use hot water or harsh chemicals in the tank where you place your dentures as this may cause damage to your false teeth.
–       Ensure that your dentures sit securely in the cleaning basket and do not overfill it as this may hamper the cleaning process.
–       Clean upper and lower dentures separately to prevent wear in case they rub against each other.
–       Do not touch the ultrasonic cleaner when it is in operation.
–       Do not immerse the entire unit in water.
–       It’s a good idea to wear gloves and protective eyewear when you handle the ultrasonic denture cleaner or cleaning solution.
–       Keep both the cleaner and cleaning solution away from children and pets.
–       Do not use the ultrasonic denture cleaner for anything other than cleaning dentures.
When you follow these guidelines, you will be able to use your ultrasonic denture cleaner safely.

Can all types of dentures be cleaned with an ultrasonic denture cleaner?

Not all types of dentures are suitable for cleaning with an ultrasonic denture cleaner. This is why you must confirm with your dentist that the type of dentures you have can be cleaned with this type of device.
Most dentures are made of acrylic or other materials that can be cleaned with an ultrasonic cleaner. However, metal-based dentures, including those with metal clasps, are not recommended for cleaning in this manner. That is because the vibrations from the ultrasonic sound waves can damage metal parts or cause them to loosen. Plus, damaged dentures should not be cleaned in an ultrasonic cleaner to avoid further damage from occurring.

Can an ultrasonic denture cleaner damage or warp my dentures?

Provided you follow the instructions that come with your ultrasonic denture cleaner, you should not damage or warp them. However, if used incorrectly, extended exposure to the ultrasonic waves can cause potential damage. Overexposure can weaken the material dentures are made from. Also, dentures that are metal-based, or contain metal clasps are not suitable for cleaning with an ultrasonic device.

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

The time it takes to clean dentures with an ultrasonic cleaner varies on several different factors. They include the type of dentures being cleaned and the amount of buildup on them. However, most ultrasonic denture cleaners have cleaning cycles that run between 3 and 10 minutes. It is vital to stay within those parameters as excess exposure to ultrasonic waves can lead to damage to your dentures. To be sure what time cycle is correct for your needs, consult the instructions that came with your ultrasonic cleaner.

Do ultrasonic denture cleaners remove stains from dentures?

Ultrasonic denture cleaners are effective in removing various stains from false teeth. These include stains caused by food, tea, coffee, or tobacco. This is because the ultrasonic sound waves create tiny bubbles that scrub away stubborn stains and reach places that you can’t normally clean properly with a brush. That being said, there are some stains that an ultrasonic denture cleaner cannot remove without the use of additional cleaning methods. These types of stains are normally caused by medications or certain medical conditions. Ultrasonic denture cleaners are also effective in removing bacteria and debris. For best results, consult the instructions that came with your ultrasonic cleaning device.

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

The types of features available on an ultrasonic denture cleaner vary from model to model. Here is a list of some of the key features to look for:
–       Size/Capacity: The size of the cleaning basket and how many dentures it can hold should be one of your first considerations.
–       Cleaning Cycles: Ultrasonic cleaners with adjustable cleaning cycles will mean they can accommodate different cleaning needs. Some cleaners have pre-set cycles. Others let you set the time.
–       Frequency/Power: Higher frequency, and more powerful, ultrasonic waves can be more effective at cleaning dentures. However, more power and higher frequencies increase the cost of the cleaner.
–       Timer: A built-in timer keeps you from overexposing your dentures to ultrasonic waves. Too much exposure can cause damage to dentures.
–       Material: A cleaner that is made from durable, high-quality materials will be able to withstand regular use and cleaning.
–       Ease of Use: Cleaners that have clear instructions and are easy to operate tend to get used more often. If you are not good with complicated things, avoid ultrasonic denture cleaners with a lot of additional features.
–       Price: Your budget will be the final determining factor on the type of ultrasonic denture cleaner you will purchase.
Don’t forget to consult with your dental professional to ensure that the type of ultrasonic cleaner you are considering purchasing is suitable for use with your type of dentures.

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. For a thorough cleaning on a regular basis, an ultrasonic cleaning unit may be your best bet.

As for which one will work the best for you, that is a decision best left up to you, however some ultrasonic cleaners for dentures on the market are designed to be used for more than just denture cleaning, and this may assist you in making your decision.
