Exactly what I needed and wanted
I had a thin black line of tartar (a.k.a. dental calculus) on my back upper molars along my gum line and wanted it to be removed.  I brush 2x's within 24 hours, floss, and use a water piker.  This product helped me remove the tartar.  The process requires patience because each tiny section of tartar seemed to require 5 minutes of application, but the product was effective and easy to use.  I initially assumed the tip on the electronic teeth scaler would be extremely sharp and I may accidentally puncture myself, but with care neither was the case for me.  Always start on the lowest vibration setting, increasing the vibration after some experience. Additionally, I relied on the YouTube channel "Teeth Talk Girl", a dental hygenist, to provide me videos of how hygienists properly use teeth scalers to remove tartar and plaque and applied them to myself.<br /><br />In regards to the other tool provided, the manual teeth scaler, please be careful because it is extremely sharp and one can easy hurt/injure your gums. I personally will avoid using this tool.
