i don't use it often.. but if i've forgtoten about Layla's teeth (hey.. it happens) and they get yellow on the back. i'll use it.. but otherwise we just brush
i bought it because when we went to NY last summer for a week and left layla with her sitter, her teeth didn't get brushed and theyw ere a mess when i got back.. so i needed something a little more powerful than just toothpaste
