Every child is different, but the first teeth usually start to be replaced by adult teeth when your child is around six years old. These permanent teeth will have been growing in the gums for some time, but it’s only when your child gets to about six that the first big tooth will start to travel through the gum. As this happens, the root of the milk tooth dissolves, making it wobbly. And because the big tooth keeps growing, it pushes the little tooth out completely to make room for itself.
