How Do Teeth Turn Green?
Teeth can turn green due to several factors, primarily related to staining and underlying medical conditions. Poor oral hygiene is a significant contributor.
-
Poor Oral Hygiene: Inadequate brushing and flossing allow plaque and tartar to accumulate. This buildup creates a breeding ground for bacteria that produce pigments, staining teeth green (as noted in the March 13, 2024 source).
-
Bacterial Pigments: Chromogenic bacteria are a leading cause of green (and orange) stains, particularly in children (March 8, 2021 source).
-
Intrinsic Staining: This type of staining happens during tooth development. It can result from a lack of nutrients or certain medical conditions (September 2, 2022 source). This is often seen as a translucent green discoloration stemming from bilirubin in the blood during tooth development (Source: PMC articles/PMC7229398/). Neonatal hyperbilirubinemia, sepsis-induced cholestasis, or biliary atresia can also lead to this (Source: PMC articles/PMC2083435/).
-
Extrinsic Staining: This staining occurs on the tooth's surface. It can be caused by certain foods, drinks, and tobacco use (March 13, 2024 source).
-
Medications: Tetracycline antibiotics taken during tooth development can cause intrinsic staining resulting in discoloration, including green hues (May 27, 2024 source).
Addressing Green Teeth
Addressing green teeth depends on the underlying cause. Regular brushing and flossing are crucial for preventing plaque and tartar buildup. Professional cleaning by a dentist can remove surface stains. More serious causes may require specific treatments determined by a dentist or medical professional.
