Review (5/5): Wow this works
My dentist did a bad job of cleaning tartar off my teeth so after seeing someone do a review on this on Youtube I gave it a shot. It removed the brown spots I had on my front teeth and that's all I could ask for. I guess it works by vibrating very fast that it weakens the integrity of the tartar until it disintegrates. Very easy to use and does not hurt at all. Just be sure to watch a youtube video on it before use. No need to use the pointy part. Be careful not to touch your gums with it during use. Worth every penny and I can use this every time I need to remove a little tartar. One of the products that is well worth the money and then some.
