iSonic F3900 Ultrasonic Denture/Aligner/Retainer Cleaner, 100-120V (tank no longer removable)

I spent hours doing research on Amazon before purchasing my first ultrasonic cleaner for the mouth guard I've worn for years. I have TMJ, and mouth guards made by good dentists for this condition are EXPENSIVE. I've always wondered why mine comes home from the dentist looking so much better than when I clean it at home. Now I have my own "at the dentist" cleaner. It makes very little noise; you can hardly hear it. After five minutes, it turns itself off. While you can add dental cleaning products to the water, you don't need to. Because I've had this mouth guard for nearly a decade, even the iSonic F3900 won't remove some of the silver-colored stains from the teeth with cavities that grind against it at night, but that does not surprise me.A dental hygienist told me that putting my TMJ mouth guard in water with a drop of Dawn dishwashing cleaner would help remove the surfactants regular cleaning doesn't, and she was right. That what I have been using, but this works even better. DO NOT use regular toothpaste on your plastic dental devices - they are abrasive and will cause more problems down the road. I have a large mouth, and I sincerely doubt that anyone's TMJ mouth guard wouldn't fit into this device.

I use this for my invalisign retainers and wow! My first test with this, I didn't pre-brush my retainers, I just threw them in with just tap water. My retainers were pretty gross so after the first run, they were cleaner but there was still some stuff on them. I flipped the retainers and ran them again. They came out like new! After that first time of double-cleaning my retainers, I only have to run them through once. I don't have to brush my retainers anymore, I just throw them in (usually upside down) and voila! I don't know about dentures or other items, but for invisalign retainers, I haven't used any cleaning powder/solution at all and they still come out fresh.It does make a noise, but I usually am hopping in the shower right away (the water blocks out the noise) or I leave the bathroom and shut the door. It's not so loud that I can hear it behind a closed door. My only complaint is that the basket no longer comes out so I have to keep the entire device near the sink (or have a super long cable hanging around the counter). But, they tell you that in the description so you know what you're getting. I wish I knew about these when I had my aligners!

I bought this because I was having trouble keeping my Invisalign braces clean. They're pretty disgusting after one night of sleeping in them, let alone if you drink coffee or wine with them in - plus, I'm a mini germaphobe, so given that I know I'll have to wear a retainer to keep my teeth clean, I wanted a way to keep it clean.I was skeptical about this product given the mixed reviews about noise, but I went with this model because it seemed to be the only one that didn't look like it was straight out of the 80s and my wife is pretty particular about the appearance of things that sit on our recently redone bathroom counters.Bottom line: I'm very happy with this purchase. It looks great, and it works great - braces are nice and clean after a quick bath. As for the noise, yeah it's loud but it only lasts for 5 minutes, so I just throw them in while I eat and it's perfect. Also, it's been working great for over a month. You do have to clean the tray inside it regularly, but it comes right off and is very easy to rinse and clean.While I can't compare this with other products on the market, I would recommend it for Invisalign users.

Was hopeful that this would work on my mouth guard since my dental insurance wouldn't cover it. $900 out of pocket... over 2 or 3 years it became... well, let's just say nasty is an understatement. Regardless how much I soaked and scrubbed, I couldn't get it clean. Took a chance on buying this... best purchase. It cleaned my mouth guard more than I could have imagined. I could see it begin to clear up immediately. I am so pleased. I will use it for both mouth guards--I bought a second once because I thought I needed to throw the first one away. So now I have one I can keep with my travel suitcase and one by my bed.

Wonderful for night guards. it cleaned the night guards just like the dentist's ultrasonic cleaner. We use it once a week with warm tap water. It will turn off when done. We leave it on our bathroom counter, takes up less space than a paperback book. The tub DOES NOT REMOVE, but it's in the bathroom and we just pour the water out the front, it's not hard and it doesn't make a mess. Wipe dry when done with clean towel and unplug when not in use, easy!!!

I have been frustrated trying to brush all the crevices of my invisalign retainer and still having it have debris stuck in places I can't really reach. I resorted to taking a pin to scrape it out which didn't work all that well. My retainer has also gotten brown tinged over the last several years (it's about 4 years old). I was skeptical this would work for both issues but since I only get it cleaned by my dentist every 6 months, I figured it was worth a shot. I bought this with retainer brite tablets, but it came with one pack of the ultra sonic cleaner. It was really easy to set up (plug in and fill with water) and the instructions were clear. I removed the plastic tray and used about half the packet of the cleaner and ran my retainer through 3 cycles (taking one ten minute break between so it didn't overheat) and the difference was amazing. I haven't used it with the retainer brite tablets yet, but just the cleaner and water removed all the stuck on junk and brightened them significantly. I'm hoping the color will brighten even more over time, but I'm just happy with how clean they are now. This is simple to use every day and even though it looks like gentle vibrations in the water (I was initially concerned it wouldn't do anything) it definitely makes a difference. Very happy with the purchase.

I am obsessive about cleaning my denture. The machine gets a workout, and has never failed to impress. I recommend it highly. It is a good size, easy to clean and works exceptionally well.
