Review (5/5): Friggin amazing!
This gets hardened plaque off teeth quite easily. I have one certain tooth that I've always had a hardened plaque issue with. This lil thing actually got it cleared off! Didn't expect much when I turned it on (it had power straight outta the box) but I was able to easily and safely grind away the plaque! Now my tooth is clear as day! I'm so happy...this literally saved me an extra trip to the dentist.
