What is the most common stain found in children?

The most common stain found in children is the green line stain, often associated with certain types of dental deposits. This stain typically occurs due to the accumulation of plaque and bacteria on the teeth, particularly when oral hygiene practices are not thoroughly followed. It is often more visible in children because their enamel is still developing and may be more susceptible to these stains.

The other types of stains—yellow, brown, and black—can occur for various reasons, including diet, medications, or environmental factors, but the green line stain is particularly noted in children due to its association with plaque biofilm and the challenges young ones may have in maintaining optimal oral hygiene. The presence of the green line stain serves as an important indicator for dental health professionals when assessing a child's oral care routine and the need for guidance in developing better dental hygiene habits.
