It is one of the few toothpastes with 1400ppm that does not burn. Now, as for effectiveness, it is still too early for me to evaluate it.

We have tried more than 6-7 toothpastes until we found a flavor that our little one likes, we always end up with toothpastes that are for younger ages. Fortunately, he likes this one and we will continue using it for a while.

I got it for my 8-year-old son, and I think it's great for transitioning from children's toothpaste, which usually has a fruity flavor, to a toothpaste closer to adult toothpaste.

Very good for use in children to get away from the fruity taste of children's toothpastes. Not at all bitter

We use it daily for 2 months.
The rating is indicative. I don't know how good it really is.
Anyway, it was recommended to me by a dentist, probably not maliciously (I asked for a toothpaste with 1000ppm fluoride).
What is certain is that for 5-6 year old children, it is quite spicy. However, they gradually get used to it.
