Review (5/5): Amazing tool
I haven't been to a dentist in almost 15 years. I typically take pretty good care of myself but nonetheless I had some fairly significant hardened plaque buildup along my bottom row of teeth. With this tool I was able to remove ALL of it in just one session.
It takes a bit to get comfortable using the tool and it required a bit of persistence to loosen some of the large chunks of plaque even with the power level maxed out, but as long as you're careful and don't jab yourself in the gums too hard then the tool is painless to use.
Highly recommend this tool if you can't afford regular dentist visits.
