My little girl is 7. She likes strawberry flavored tooth paste and Disney character tooth paste. I also looked at a lot of the adult tooth paste and children’s tooth paste and found that the adult and kids ones contained the same amount of fluoride. I looked at crest for adults and Colgate for adults. Same amount of fluoride. Why should I switch to an adult tooth paste for her when they both contain same amount of fluoride. It also says that adults can use children’s tooth paste too. I’ve looked on the back of every kids tooth paste and says adults and children 2 years plus on them.
