It actually works
I was skeptical at first. But this device does remove plaque from teeth and quite efficiently and easily. I am 2 weeks out from my bi-annual cleaning. I had some plaque build-up on my lower teeth (front and back). I put the device on high and it removed all of the built-up plaque. I was amazed. The back of the teeth was a bit harder for me. My advice is don't be afraid of the device harming your teeth. Once I "dug" in the plaque was gone!
