Dental experts have identified five popular drinks that could permanently stain teeth and erode enamel, according to a study by Sanitas. The findings highlight that even diligent cleaning may not prevent discolouration from these beverages.
Coffee, red wine, and dark soft drinks contain chromogens—pigments that adhere to tooth enamel. Over time, layers of these colourants can alter the shade of teeth, leading to a yellowed appearance. The study warns that regular consumption of these drinks contributes to enamel erosion, making teeth more susceptible to staining.
Sugary drinks such as fizzy pop and fruit juices are also major offenders. Their high sugar content fuels harmful bacteria in the mouth, which erodes enamel and leaves teeth vulnerable to stains. Acidic citrus juices, particularly orange and lemon, were singled out for their ability to wear down enamel and increase porosity, potentially exposing the naturally yellow dentine layer beneath.
The experts advise that reducing intake of these drinks and maintaining good oral hygiene can help mitigate damage, but caution that some staining may be permanent once enamel is compromised.
