They work, but taste terrible.
My kids really wanted disclosing tabs after seeing them on social media.  They were excited when they got these in their Christmas stockings. The tablets do what they're supposed to do: highlight plaque and residue on the teeth. But, these tablets taste awful! They have an overall bitter flavor. I have tried crushing them and mixing it with mouthwash to mask the flavor, but the teeth don't get dyed as much. I will look into other tabs and hope for a better flavor.
