Therefore, I have two different Scaler ordered in the hope of being able so solve the problem. The build quality is impeccable, but to me it is just too risky, so at your own teeth to remove the tartar and then damaging the enamel or hurting the gums. Also, my test results were quite mixed because of poor accessibility of my "problem areas".
For about half a year I use Listerine mouthwash with tartar protection (LISTERINE tartar protection). What can I say, the formation of tartar with me now tends to zero!
Although I now not used by me there's 4 stars for a good quality product.
