Tooth-colored fillings require less preparation than traditional metal fillings, which means fewer shots and less drilling. They're also very natural-looking, so you won't even notice a difference in the appearance of your child's smile. Tooth-colored fillings are biocompatible and wouldn't damage the tooth's natural tissues and perfectly blend in. Their expansion and contraction rates are quite similar to those of the enamel. Hence, they wouldn't damage the teeth when your child eats hot or cold foods.
