Pink discoloration of an anterior tooth indicates tissue within the pulp space is actively changing and visible through the enamel. This arises when internal root resorption progresses: clastic cells remove dentin from inside the tooth and the pulpal tissue, often inflamed and vascular, fills the resorptive area. Because the enamel on an anterior tooth is relatively translucent, the reddish-pink tissue inside can be seen through the crown, creating a pink tooth appearance. This presentation is the most characteristic sign of internal root resorption.

External root resorption affects the outer root surface and does not typically produce a pink crown hue; calcific metamorphosis involves calcification of the pulp and usually leads to yellowish or brown discoloration rather than pink; a fracture can cause color changes from hemorrhage, but the classic pink tooth is tied to internal resorption.
