Teeth are not naturally completely white.
According to Listerine, as cited by LADbible, teeth often become more yellow with age because enamel gradually wears down, making the more yellow layer beneath the enamel more visible.
Smoking, poor oral hygiene, and dental injuries can also contribute to changes in tooth color.
Food and drinks
Dark berries such as blueberries and raspberries can stain teeth due to their strong natural pigments.

Listerine recommends rinsing your mouth with water afterward.
Wine can also affect tooth color. Red wine may leave dark stains, while the acidity in white wine can contribute to teeth appearing more yellow.
Hidden causes
Soft drinks are not only a problem because of their sugar content.
The acid found in many soft drinks can damage enamel, making teeth more susceptible to discoloration.

Ketchup may also play a role, as it contains spices that can gradually affect the color of teeth over time.
Yellow teeth are not solely the result of inadequate brushing. According to Listerine, dark berries, wine, ketchup, and soft drinks can all contribute to teeth becoming more yellow, even in people who brush their teeth every morning and evening.
