I've known a few kids who have started loosing teeth early. Are the new teeth coming in? The only thing you need to worry about is taking really good care of his new adult teeth since he is still kind of young to do a really good job brushing on his own. Most of the other kids at school lost their first teeth in kindergarten, while my boys were both in grade one before they lost their first teeth. There is a range of normal.
