Tobacco stains have a significant impact on teeth, and they may indeed become intrinsic over time. When tobacco is used, it can leave behind deep stains due to the nicotine and tar present in tobacco products. If these substances are not removed promptly, they can penetrate the tooth enamel and become ingrained within the structure of the tooth, leading to intrinsic staining, which is more difficult to remove than extrinsic stains.

Intrinsic stains occur when the discoloration is not just on the surface but has affected the interior layer of the tooth. This is in contrast to superficial stains that can typically be removed with polishing or whitening treatments. Understanding how tobacco can lead to intrinsic stains highlights the importance of oral hygiene and regular dental check-ups for smokers to mitigate the potential long-term effects on their dental health.
