Great water flosser
Color: Pink+purple
Got it for my 10 year old with braces and it works great! She even takes it to sleepovers! It’s so portable and the travel safe design is great. It’s a very reasonable price as well. Would highly recommend

Works great.
Color: Blue+red
I love how easy this children’s dental floss is. My child with ASD is able to use with little to no help. it’s been years trying to get my child with sensory sensitivities to floss or brush teeth without a HUGE STRUGGLE, however this is very gentle and something that makes our oral health care routine smoother. ( if you know, you know!!) It is very similar to the viral “ usmile” adult version water flossers. My only complaint/issue with this is that it collapse pretty easily and sometimes it’s hard to keep in the locked position while flossing teeth. Overall a good product, and recommend.?

Good for kids
Color: Blue+red
A little powerful for my 8 year old at first but after he got the hang of it, he loves using it.

Great for dental appliances
Color: Pink+purple
My daughter has a dental appliance that can get food caught in it. We were told to try a water flosser to get the trapped food out. This has done exactly that. Very happy with it.
