Questonable at best
As stated by others this comes with no pamphlet or information of any kind. They also took a ridiculously long time to arrive.<br />I decided to try one (I hadn't read the reviews suggesting partial tablets) and it arrived my teeth, gums, lips and sink. After five minutes of scrubbing most of my tongue is still purple/black. I couldn't see where it stuck to plaque until I had rinsed with water several times because it was EVERYWHERE. I am going to try a partial tablet tomorrow night but I have a feeling I will be throwing these away.
