Which surface tends to be affected by intrinsic tobacco stains?

• A. External tooth surfaces
• B. Cementum surface
• C. Enamel surface
• D. Root surface

Answer: (C)

Intrinsic tobacco stains are typically associated with the enamel surface of the teeth. These stains occur when nicotine and tar from tobacco products penetrate the enamel and become embedded within the tooth structure. Unlike extrinsic stains that affect the external surfaces of the tooth and can be removed through polishing or whitening treatments, intrinsic stains become more difficult to treat since they are imbedded within the enamel or even deeper, requiring more advanced dental procedures to manage. The enamel surface is the outer protective layer of the tooth and is susceptible to staining from various dietary and lifestyle choices, including tobacco use. Understanding the mechanisms of how these stains occur emphasizes the importance of preventive measures, such as oral hygiene and tobacco cessation, to maintain the aesthetics of the smile and the overall health of the teeth.
