Brown Tobacco Stain is typically found where in the mouth?

Brown tobacco stains are typically associated with the root surfaces of teeth, especially because they often accumulate in areas that are less accessible and more prone to plaque retention. The heaviest deposition generally occurs on the roots, particularly in individuals who smoke or chew tobacco. The chemical compounds in tobacco products contribute to the staining and can become embedded in dental calculus as well.

In contrast, while tobacco stains can be found on smooth surfaces, they are not predominantly located there. Occlusal pits might trap some stains, but their irregularity would not typically lead to the heavy accumulation seen with tobacco. Additionally, tobacco stains are not confined to anterior teeth; they can affect any tooth, making the claim that they are found only on anterior teeth inaccurate. Therefore, the correct understanding of the location of brown tobacco stains focuses on the roots.
