At 7 years of age loosing front baby tooth is normal as this is the normal shedding time of front baby tooth. As the tooth is hollow that means the roots are resorbed and tooth was supposed to be replaced by adult tooth. The nerves which you are seeing are actually the raw socket and in this area the adult tooth will come out and it will take normally around 3-4 weeks and you donot need to do anything. Just take care that he maintains good oral hygiene. for more info on dentition you can read this article.... www.identalhub.com/article_human-dentition-233.aspx
