A yellow-brown hue of an anterior tooth after trauma points to calcific metamorphosis of the pulp, or pulp canal obliteration. In response to irritation, odontoblasts lay down abundant calcified dentin, gradually filling and narrowing the pulp chamber and root canal. That increased calcification changes how light passes through the tooth, giving it a yellow-to-brown appearance. Radiographs typically show progressive narrowing or disappearance of the canal space, which helps distinguish this from other conditions. External root resorption would alter the root surface, and internal root resorption would create a radiolucent defect within the canal, not a color change. In practice, this color change signals a potential endodontic challenge due to canal obliteration, with management focused on careful imaging and planning if intervention is needed.
