Review (5/5): Works great for minor tarter buildup!
Worked great! I've tried a new toothpaste that somehow was actually reducing my tarter buildup but there was still a stubborn little bit that just wouldn't go away. I'd say don't be afraid to go in there and get after it. It was really great to see it actually break up the tarter. I honestly wasn't expecting it to do much at all. I'm glad I was wrong.
