Top 5 Best Ultrasonic Retainer Cleaners of 2024 Clean Retainers, Aligners, Dentures Nightguards and More
- Last Updated – February 20, 2025
Retainers are an essential part of orthodontic treatment. They help maintain the position of your teeth after braces or aligners. However, keeping them clean can be a challenge, especially with traditional brushes and toothpaste. That’s why ultrasonic retainer cleaners have become increasingly popular among orthodontic patients.
Ultrasonic retainer cleaners use high-frequency sound waves to remove dirt, bacteria, and other debris from retainers. They are easy to use and can clean your retainer thoroughly in just a few minutes. Moreover, they are gentle on your retainer, ensuring that it stays in good condition.
When looking for the best ultrasonic retainer cleaner, the critical thing to consider is its effectiveness. You want a cleaner that can remove all the dirt and bacteria from your retainer without damaging it. Other factors to consider include the size of the cleaner, its ease of use, and its price.

What is Sonic Fresh?
To grasp the magic behind Sonic Fresh, let’s delve into the science of ultrasonic cleaning. Ultrasonic cleaning is a process that utilizes high-frequency sound waves to generate microscopic bubbles in a liquid (usually water). These bubbles rapidly expand and collapse in a phenomenon known as cavitation. When these bubbles collapse near the surface of an object (in this case, dental appliances), they produce intense micro-jets of liquid.
These micro-jets effectively dislodge and remove contaminants like plaque, bacteria, and debris from the object’s surface.
It’s a scientifically proven method used in various industries, including dentistry, jewelry, and electronics manufacturing, for its exceptional cleaning capabilities.

Reviews
Easy to use, feel more confident putting back in my mouth...
5/5
I finally decided to “bite” the bullet (pun intended) and purchase a nightguard for teeth grinding, (even though it was not covered by my insurance but anyway…). Because I had spent that money on a nightguard, I decided it was also worth the investment to keep it clean and ensure that I was not just putting germs back in my mouth every night. This device is straightforward to use – open the cap, put in water, put in the nightguard, close the lid, and push the start button.
It takes longer than you think to work, but that is fine. Other reviewers mentioned the noise, so I thought it would be horrible, but honestly, it’s OK – it sounds like a slightly louder electric toothbrush. Just walk away for 5-10 minutes and then come back.
I haven’t had any issues, and I feel better popping this nightguard back into my mouth all night, knowing I’m sanitizing it.
Gets Gunk Off!
5/5
I’m a little crazy about making sure my Invisalign retainer is clean. I got this for the UV feature to kill bacteria and I’m happy with it. My retainers look and feel clean after I put them in. I don’t mind the wait because I know it means they’re actually getting cleaned and this isn’t a gimmick product to make me feel like they’re being cleaned. You can see the difference when they come out.
Super Clean Feeling!
5/5
I just got this. I’ve only used it a couple times so far. I have a night guard. I was told to clean it by just brushing it with toothpaste. And occasionally soak it in some denture cleaner. The thing always felt or smelled gross.
After using the ultrasonic cleaner it finally felt clean like the day I got it. It’s a little noisy but it’s only in use for 5 min. Worked great. Simple to use.
Thrilled!
5/5
I am thrilled there is something to specifically clean retainers. I love this one only takes 5 minutes to clean the retainer. With UV lights, it’s hard to tell how clean the retainer is getting, but the unit seems to be doing its job. The best part is there is no chemicals to clean my retainer so this is exactly what I was looking for.
Powerful, Clean and Quick
5/5
I was brushing my night guard every morning and I never knew if I was cleaning it “well”. This device cleans all the germs and bacteria. My night guard was clean and the Powerful dual clean made me feel like my guard was brand new. This device took five minutes to clean and the sounds was perfect. The sleekness of the machine is beautiful on my bathroom countertop. One of my favorite hygiene product. Will continue to use it daily.
Quick and Easy to Use! Yay to Convenience!
5/5
Absolutely love this product to use for cleaning for retainers. I used to use tablet cleaners for my retainer, in which the retainer would soak in water with a tablet, this often created a mess. With the Sonic Fresh cleaner, there is a factor of convince now. I can put my retainer in for a quick clean, usually 5 minutes or so, and I know that I can trust it has been disinfected properly. Great product and definitely recommend!
