Maintaining clean, odor-free dental appliances like dentures, retainers, and mouthguards is a daily concern for millions of users. While traditional effervescent tablets like Efferdent offer a tried-and-true method for freshness and stain removal, ultrasonic cleaners have gained popularity for their deep, hands-free cleaning ability. Naturally, many people wonder: can these two methods be combined? The answer is yes—but with a few important notes to keep in mind.
Efferdent and ultrasonic technology can work in tandem to offer a cleaner, brighter result—if used correctly.
Why Combine Efferdent with Ultrasonic Cleaning?

Combining Efferdent tablets with an ultrasonic cleaner offers a powerful, dual-action approach to dental hygiene. Efferdent contains active oxygen-releasing agents that help break down plaque, bacteria, and surface stains on retainers, dentures, and aligners. When used alone, it’s effective—but pair it with the mechanical action of ultrasonic cavitation, and the results are dramatically enhanced.
The ultrasonic vibrations generate microscopic bubbles that reach into tiny crevices and tight contact points where manual cleaning and soaking can’t reach. As Efferdent dissolves and fizzes in the water, the chemical reaction works alongside these vibrations to lift debris, loosen biofilm, and refresh the surface of oral appliances without abrasion. This synergy means fewer residues, better odor control, and a noticeably fresher device after each cycle.
How to Use Efferdent in an Ultrasonic Cleaner
Using Efferdent in your ultrasonic device is easy, but following these steps will ensure optimal results and prevent potential mishaps:
Fill the ultrasonic tank with warm (not hot) water—typically between 35°C and 45°C. Add one Efferdent tablet and allow it to dissolve briefly before activating the ultrasonic cycle.
Place your dental appliance in the provided basket. Do not place items directly on the tank bottom, as this may reduce cavitation effectiveness and cause minor vibration damage.
Run the ultrasonic cleaner for a short cycle—usually 3 to 5 minutes is enough. Avoid overly long sessions to prevent surface dulling of acrylic or plastic parts.
After cleaning, rinse the appliance thoroughly under running water and dry with a soft, clean towel.
Avoid mixing Efferdent with other cleaning solutions in the same session, as unexpected chemical interactions may occur.
When Not to Use Efferdent with an Ultrasonic Cleaner

While Efferdent works well with most retainers and denture plastics, there are times when caution is advised. Some oral appliances contain metal components, soft liners, or adhesives that may degrade faster when exposed to repeated chemical and mechanical action. For example, partial dentures with metal clasps might tarnish or corrode over time if exposed to overly frequent ultrasonic cleaning with active agents.
In these cases, it’s better to alternate methods: use Efferdent separately for soaking on some days, and rely on the ultrasonic cleaner with plain water or a gentler solution on others. Also, avoid using Efferdent with extremely hot water in ultrasonic devices, as it may accelerate material fatigue or distortion. If your dental device came with care instructions, it’s always best to check for any brand-specific recommendations or cleaning restrictions before combining methods.
Efferdent vs. Other Cleaning Solutions
Efferdent is one of many cleaning tablets available, but it remains a go-to option because of its balance of cleaning power, safety, and accessibility. Compared to harsh alcohol-based or acidic cleaners, Efferdent is gentler on plastics and oral appliances. It doesn’t contain bleach or abrasive ingredients, making it safe for most daily-use retainers and dentures.
That said, Efferdent alone cannot reach certain problem areas—such as bacteria hiding in microgrooves or hinges—which is where ultrasonic cleaners shine. Their combined use produces results far beyond what either method can achieve alone.
Why Choose Granbo Ultrasonic Cleaners for Dental Use

Granbo ultrasonic cleaners are designed with precision, safety, and versatility in mind—making them especially well-suited for dental hygiene routines. Whether you’re cleaning dentures, retainers, aligners, or night guards, Granbo units offer consistent cavitation performance at 48kHz, a frequency known for effectively dislodging plaque and biofilm without damaging delicate plastics or metals.
Unlike generic models, Granbo cleaners feature intelligent temperature control, a built-in degas mode, and multiple cleaning cycles, allowing users to customize each session based on the item’s material and level of buildup. The result is a more thorough and even clean, reaching into grooves and tight contact points where manual brushing or soaking tablets alone may fall short.
In addition, select Granbo models include optional UV sterilization, providing an extra layer of hygiene—a key advantage for users with sensitive oral health needs. With compact designs and intuitive operation, Granbo ultrasonic cleaners offer a trusted solution for daily dental appliance care at home or in clinical settings.
A Clean You Can Feel, A Routine You Can Trust
Establishing a reliable cleaning routine isn’t just about maintaining appearances—it directly impacts oral health and comfort. By combining Efferdent with ultrasonic cleaning a few times a week, users experience not just visual cleanliness, but a tangible difference: no lingering odors, no slimy residue, and no chalky build-up over time.
Consistency is key. With just a few minutes of effort each day, your aligners, dentures, or retainers can remain crystal-clear and fresh, minimizing the risk of oral infections and staining. Granbo’s ultrasonic systems, paired with reputable cleaning tablets like Efferdent, create a dependable at-home care solution that feels effortless and effective. Over time, this clean isn’t just something you see—it’s something you feel every time you wear your appliance.
