Confusion with seeetener for 8months old

Babe has 6 teeth now at 8 months old. I decided to buy the Hello Training toothpaste and toothbrush with Apple flavor in it. I tried to taste and swallow it before letting my babe try. It’s pretty sweet though the ingredients are all decent. Babies are not supposed to get used to sweet taste so early. But if I brush my babe twice with these toothpaste after waking up and before bedtime, I’m afraid he will he use to the sweet taste. Is this concern valid?
