These Work Really Good
These work really good only thing I don't like about them is that they are very sticky so you have to wash your hands and baby face after you are done using them. My baby had some yellowing on his top teeth, but as soon as I used these it was gone after the 2nd use. The 1st one I used you could see how some of the yellow went away and then the next night I used one and it was gone. They shine the teeth up very well and the taste is good. I just wish there was another way to use these because my baby bites my finger sometimes!! Great purchase:)
