Why are permanent teeth darker than primary?

Permanent teeth tend to be darker than primary (baby) teeth due to differences in their mineral composition and structure. Permanent teeth have a thicker layer of dentin, which is more mineralized and can give them a darker appearance. Additionally, the enamel of primary teeth is thinner and more translucent, allowing the underlying dentin to show through less prominently. Over time, factors like dietary habits, oral hygiene, and exposure to staining agents can also contribute to the darker color of permanent teeth.
