Dark brown stains on teeth are typically associated with what behavior?

Dark brown stains on teeth are commonly associated with tobacco use due to the staining agents present in tobacco products. When tobacco is smoked or chewed, tar and nicotine can deposit on the teeth, leading to significant discoloration over time. This discoloration is often a deep brown or even black, depending on the extent of use and oral hygiene habits.

Tobacco not only causes staining but can also lead to other dental issues, such as periodontal disease and an increased risk for oral cancers, making understanding its impact on oral health highly relevant for dental professionals. While certain minerals in a diet, frequent soda consumption, and specific mouth rinses can also lead to staining, the characteristic dark brown stains specifically correlate more strongly with tobacco use.
