Review: What a difference this machine makes. - I’ve been using the iSonic F3900 Ultrasonic Cleaner for my dental appliances, and it has quickly become part of my daily routine. What stands out most is how simple it is to use — just fill the stainless‑steel tank, drop in half an Ultrasonic Cleaning Tablet, place the appliance inside, and tap the button. The unit runs a 5‑minute cycle automatically and shuts off on its own, which makes the whole process effortless . For cleaning, I use distilled water instead of tap water, and the results have been excellent. After two 5‑minute cycles, my bite block came out genuinely clean, with buildup lifted off and the surface looking noticeably fresher. The CTAR01 tablet dissolves quickly and boosts the ultrasonic action, which the product page notes is exactly what it’s designed for . The machine is compact, quiet, and doesn’t require any fiddling or adjustments. It’s truly a set‑it‑and‑forget‑it cleaner — perfect if you want something that works without hassle. Based on my experience, it delivers exactly what it promises: a fast, effective clean with minimal effort. Overall: ✔ Extremely easy to use ✔ Distilled water + CTAR01 tablet works great ✔ Bite block came out fully clean after two cycles ✔ Reliable 5‑minute automatic cleaning ✔ Compact and quiet
Review: iSonic F3900 Ultrasonic Dental Cleaner Does The Job - The cleaner works great and works as described. I have noticed a much cleaner, clearer mouth guard after usingt teh iSonic F3900 clearner. I use a Polident retainer cleaner tab that augments the iSonic's cleaning capability . This is a great item for personal hygiene at a reasonable cost.

## Questions & Answers

**Q: I just used this unit for the first time yesterday evening. The unit quietly hums but there is no movement of the water. Is the unit defective?**
A: You don't see movement.  However, put one finger in the unit while it is on and you should notice the vibrations.  If you don't, then something is wrong.  But just looking at it, no, the water doesn't move.

**Q: Can this be used with a flex denture?  I can't use toothpaste, mouthwash or cleaning tablets because the denture will change color.**
A: I use it on my flex bridge with Val-Clean made for this type of denture. Buy it at valclean.com for ½ the price on Amazon. I've been using it for many years now. They get clean and still flexible.

**Q: When this item is used to clean a night guard, should it be used every day?  I typically just brush my night guard with my toothbrush & toothpaste every morning, but do a weekly soak in a glass with denture cleaner.  Do you add any sort of cleaning agent when using this item?  Thanks!**
A: I use mine for my night guard.  My dentist says all of these 'expensive' cleaners are unnecessary.  Use distilled water and 1/4 teaspoon of baking soda and clean your retainers or dentures every night.  I do this and once a week I brush my retainers with my toothbrush... they have been very clean and undamaged for years.  Saves money and it works... I like a win-win.

**Q: Has anyone owned this for over 2 yrs.  From the review, it breaks down too easily.  Anyone know model that will last me more than 5 yrs for**
A: I bought mine July 2018, and it broke Oct 2020.  I didn't use it frequently either.  It does a great job but isn't durable. So, based on my experience, it will not last even 2 years.
