desertcart.com : iSonic Ultrasonic Denture/Aligner/Retainer Cleaner for All Dental and Sleep apnea appliances (F3900) : Health & Household

Review: It's doing a great job - So far it's working as advertised. Easy to use & clean. Purpose of the purchase is to clean dentures & it does that very well. This device is for a person with dementia. They have enough challenges getting through each day. This device eliminates one of those challenges. It's setup for them & all they need to do is put their dentures in the device. Their dentures are cleaned within minutes - 5m/quick or 10m/deep clean.
Review: 6 Years usage & excellent results - I have used the Isonic ultrasonic cleaner for my dentures for six years. Being a clean freak I do normal denture cleaning with warm water and brush. I then place my dentures in the tank along with a standard denture cleaning tablet and warm water. I allow the appliance fro soak overnight. A thorough rinse with warm water for the dentures as well as the ultrasonic cleaner each morning and the process is quick with excellent results. My dentist has commented on the cleanliness of my dentures at every check up. My daily routine may seem excessive but my appliance is clean and fresh daily.

## 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.
