What color is tertiary dentin typically considered to be?

Tertiary dentin, also known as reparative or reactive dentin, is typically considered to be brown. This type of dentin forms in response to stimuli such as caries, wear, or trauma as a protective mechanism by the dental pulp. The coloration of tertiary dentin is influenced by factors such as the presence of extrinsic material, the health of the pulp, and the amount of mineralization. Over time and under stress, the dentin may acquire this darker hue, which differentiates it from primary dentin, which tends to be lighter in color. Understanding the characteristics of tertiary dentin is essential for dental professionals in diagnosing and treating dental issues effectively.
