Review (4/5): The whole package works
I wanted to try something that would chip away at my tartar buildup. I've had it for years, but can't afford to go to the dentist. The first session was only using the scrubber. It didn't do much. The second session, however, I used the provided pick to crack the tartar. After a few pieces were taken out, I used the scrubber and all that tartar just fell off. You should use the whole cleaning package for the best results.
