Tooth discoloration most commonly results from pulp necrosis. When pulp tissue dies: 1) Hemoglobin breaks down into iron sulfide and other dark pigments, 2) Protein degradation products penetrate dentin tubules, 3) These pigments become embedded in the tooth structure, 4) The discoloration progresses from pink to dark brown/gray over time. This is more common than hyperemia (which is reversible), pulpal abscess (which may not always cause visible discoloration), making pulp necrosis the primary cause of intrinsic tooth discoloration.
