My kids like our adult toothpaste better than the "fruity" kids ones. BUT, my dentist said that until they are 12 years old they should not use adult toothpaste. That it is too harsh/abrasive for their young teeth.
My eldest, just turned 12 last month, also finally lost his last baby tooth, so he is good to go using "regular" toothpaste now. My youngest is 9. They both prefer the Crest pro-health (?) ones. But according to my dentist, the younger one should still be using "kids" toothpaste. So I guess Kids Crest gel is what she'll be using for a few more years. I don't think it is as sweet tasting as some of the really "kiddie" ones by Oral B. If she doesn't like the mint kind, you might try out the Tom's of Maine line... they have kids toothpastes too. One is strawberry flavored.
oh... one other thought. You might want to watch her a few times to see how much she is putting on her toothbrush. Kids have a tendency to 'overapply'. And frankly, on a few occasions I have gotten more than I intended on my own brush, and that minty taste is WAAY strong if you get too much. Maybe if she uses less, she will like it more? It only takes a pea sized amount - not an inch on the brush, lol.
