iSonic F3900 Ultrasonic Denture/Aligner/Retainer Cleaner for all dental and sleep apnea appliances, 110V 20W (tank no longer removable) , White , 0.4Pt/0.2L

I am giving this 5 stars and will update if needed in the future.6/23 I REALLY appreciate legit reviews with pictures and videos so I am making an effort to review more to help others. Lots of folks post about these ultrasonic machines using relatively new Invisalign-type retainers which just isn’t going to compare to a night guard or multiple-year-old retainer. I read hundreds of reviews before deciding on this one and forgoing a used professional dentist-grade machine on eBay. The negative first: I don’t LOVE that I can’t remove the tank to drain and rinse but I won’t ding them for that unless it becomes an issue later. Positives: relatively small realty space, quiet, easy to use, seems to do the job. My guard is almost 3 years old and has darkening stains in the molars especially. I typically brush it with a toothbrush, a scant amount of toothpaste and cool water. I used all the retainer powder provided and did 4 cycles. The first two cycles I used the retainer powder provided. I gave it a 10-15 min break her the instructions to cool down then ran it two more times using half of a retainer brite tablet each time. I’m super impressed. Hard to tell via images but it did VERY well removing the darkened spots almost completely. I’m sure repeated use will get the job done entirely.

I use this daily with teeth aligners, no longer do they smell terrible like my first rack did. Mind you, I only have them for a week at a time. Despite using this on a bathroom counter with easy sink access, I decided to try dissecting the tub, based on other reviews. I discovered that the tub is now hard wired in, so please don’t bother attempting if you buy this after 2024. This new design should help with the issue some had where water degrades the contacts, since it’s now wired. I should probably caulk the gap now though.Edit: this thing is AMAZING for cleaning tooth brushes, can’t believe I’ve been going my whole life changing every few months, never again!

This product works great. All of us use it in our house for cleaning clear retainers. It cleans them really well and they look good as new. We've had the device for two years and suddenly it just stopped working. The blue light comes on but no cycle runs. I did just notice other reviewers that said the same thing. I will purchase another one because we love how it works, but the life cycle is unfortunate. Hoping it lasts longer this time around.
