They work . Read the instructions :)
Yes they do taste like purple dye . Yes they will can stain your sink . BUT THEY WORK.<br />With adult supervision these work exactly as they are supposed to . If your worried about them staining your sink have your child spit in the trash or heck outside . I have ZERO issue with them leaving dye on my children’s teeth . We aim to use these once a week or minimally once a month just to see if any spots are being missed .
