Unerupted foetal tooth. Coloured lightmicrograph of the root structure of an unerupted foetal tooth. The central pale area is the highly cellular dental papilla, which will go on to form the pulp cavity. The red layer next to the dental papilla is dentine, which has been laid down by odontoblasts. The layer underneath the dentine is tooth enamel, which has been laid down by ameloblasts. The ameloblasts surround the enamel, forming the final layer. The root is not fully formed until after tooth eruption.
