What causes yellow effects on the facial surfaces of anterior teeth?

• A. Fluoride exposure
• B. Beverage erosion
• C. Poor oral hygiene
• D. Cavity formation

Answer: (B)

The phenomenon of yellowing on the facial surfaces of anterior teeth is primarily associated with beverage erosion. This occurs when acidic beverages, such as soft drinks, fruit juices, and sports drinks, come into contact with the teeth. The acids in these beverages can erode the enamel, which is the outer protective layer of the tooth. As the enamel wears away, the underlying dentin, which is naturally more yellow in color, becomes more visible. This results in a yellowish appearance on the affected teeth. While fluoride exposure can lead to mottling or discoloration of enamel in cases of excessive fluoride, it does not specifically cause a yellow effect. Poor oral hygiene can lead to plaque and tartar buildup, which may contribute to discoloration but typically presents more as brown or dark stains rather than yellowing. Cavity formation results in localized damage to teeth that can lead to dark spots, but again, this does not specifically cause the yellow effect. Thus, beverage erosion is the most likely cause of noticeable yellowing on anterior teeth.
