Root Canal for Kids

Young children can lose primary (baby) teeth and even immature permanent teeth when the pulp, the living tissue inside a tooth, becomes infected. This is often the result of trauma or dental caries (tooth decay) and creates a special problem for the child. The primary teeth provide important guides for the newly developing permanent teeth that will replace them. And injury resulting in loss of young permanent teeth can be even more troublesome, because neither tooth development, nor jaw growth is complete.
