What type of stain can be found on children's teeth due to poor hygiene?

The presence of green stain on children's teeth is often associated with poor oral hygiene and certain habits, such as prolonged exposure to food debris and plaque biofilm. This type of stain is frequently linked to the presence of chromogenic bacteria, which can thrive in an environment where oral care is lacking.

Green stain typically appears on the gingival third of the tooth and is more common in young children, especially those who may not have established a consistent brushing routine. It can appear as a greenish-yellow discoloration and tends to be more noticeable on primary teeth. The importance of recognizing and addressing green stain is crucial for pediatric dental health, as it provides an opportunity to educate children and their caregivers on proper oral hygiene practices to prevent further staining and promote overall dental health.

In contrast, other types of stains—like yellow, black, or brown—can also appear due to different causes, including dietary influences and certain medications. However, green stain is particularly indicative of poor hygiene practices in children, making it relevant to the question.
