Fluorised junior toothpaste

I've received samples of this toothpaste from a friend of mine. I am a full-grown adult with adult teeth. My first impression when I tested this toothpaste was the strong fluorine/fluoride taste which helps preventing tooth decay and strenghtening your teeth. It also has a sweet minty taste. My teeth are already badly damaged because I tend to grind my teeth (due to frustrations) which is a very bad habit I know. So my teeth are in desperate need of more protection. Unfortunately most adult toothpastes contain much less fluorine than the kids' versions. It is a shame because fluorine is a safe ingredient. I also recommend not rising it abundantly in order to leave it to work especially before going to bed.
