Why do your teeth turn green?

Teeth can turn green due to several factors, primarily the accumulation of certain pigments from foods, drinks, or poor oral hygiene. Certain medications, like those containing chlorophyll, or conditions like dental enamel erosion can also contribute to discoloration. Additionally, exposure to high levels of copper, such as from drinking water, can lead to a greenish tint. Maintaining good oral hygiene and regular dental visits can help prevent discoloration.
