Dens invaginatus results from the enamel organ folding inward during crown formation, specifically the inner enamel epithelium invaginates into the dental papilla. This infolding creates an enamel-lined pocket that can extend into dentin and even the pulp in more severe cases, giving a tooth-within-a-tooth appearance. The inner enamel epithelium is the layer that gives rise to enamel, so its inward folding is the defining change. The other structures—dentin matrix, pulp chamber, and enamel surface—don’t undergo this inward invagination as the initiating event, which is why the invaginated structure is the inner enamel epithelium.
