Listings identify fluoride as the active ingredient and, in specific cases, name the compounds used: sodium monofluorophosphate or sodium fluoride.
They highlight a kid-friendly bubblegum flavor and a color-changing formula that shifts from blue to pink (some listings note the change occurs after about 2 minutes). The color change is promoted as a way to help kids brush longer.
Warnings vary by listing but commonly include 'Keep out of reach of children' and age restrictions such as 'Not for children under 2' or 'Do not use on children under age 3.' Check each product label for specific age guidance.
Some listings explicitly state exclusions such as 'No Microbeads Added' and 'Triclosan-Free.'
