What is a common color range for non-vital tooth stains?

Non-vital tooth stains typically fall within the color range of black to brown. These stains occur as a result of necrosis or death of the pulp tissue within the tooth, which can lead to the absorption of pigments from blood or other materials within the tooth structure. Consequently, the most commonly observed colors for these non-vital stains are shades of black and brown, giving a clear indication of the underlying dental health issues.

On the other hand, while shades from light yellow to magenta may occur in other dental conditions or as a result of staining from dietary sources or other factors, they do not represent the typical appearance of non-vital tooth stains. Therefore, the answer that indicates black and brown is most aligned with the characteristics of teeth affected by non-vitality, making it the correct choice.
