I have worn an upper partial plate with 2 front teeth for over 50 years. My current partial is 42 years old. I have always brushed it several time daily. Yet over the years, I have noticed calcified material on either end, and stains on the front surface and between the two teeth. No amount of Efferdent has ever been effective in removing the calcification or staining. Year after year, the stains just keep getting worse.Desperate for a solution, I decided to try an Ultrasonic Cleaner. I purchased the iSonic F3900 with the hope it would do a proper job. Amazon delivered the unit in two days, and I read the instructions to make sure I used the device correctly. The F3900 came with a small packet of cleaning power. I wiped down the metal bowl with a damp cloth and mixed up a 1 cup batch of cleaning solution. The instructions said it was not necessary to use the plastic strainer, so I did not use it.I inserted my upper partial plate into the bowl of the F3900 and poured the solution into the bowl, stopping just before reaching the Max fill line. I plugged in the unit, closed the lid, and pressed the "On" button. The F3900 started to hum slightly, but if you looked into the bowl, you could see just the slightest agitation of the liquid solution inside the bowl. Compared to watching the foaming action of Efferdent, it didn't look as if anything was really happening. In 5 minutes, the unit turned itself "Off".The instructions say you can use the unit for up to 15 minutes before giving it a rest to cool the ultrasonic transducer. I go ahead and run the F3900 for one more 5 minute cycle, a total of 10 minutes. Even during the second cycle, it looks as if hardly any cleaning is taking place. After the end of the second cycle, I open the lid and remove my partial plate. I rinse the denture throughly under running water and begin my inspection.The calcification on either side of the teeth, GONE ! The dark stain between the two teeth, GONE ! The staining on the front surface of the teeth, GONE ! My 40+ year old partial plate looks as if it just came from the factory. WOW! I can not believe my eyes. After all the years of trying to scrub away the calcification and watching Efferdent try to foam away the stains, the iSonic F3900 has just performed a miracle on my denture. All I can say is WOW, WOW, WOW!

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!
