White wine stains teeth in the same as red wine, say researchers from the New York University College of Dentistry.
Researchers carried out experiments with cow’s teeth, exposing them to white wine and tea. They found that the teeth were significantly more stained than when they were exposed to a combination of tea and water. The researchers however, found that red wine still poses the greatest risk to staining of human teeth.
Two sets of six cows’ teeth were soaked in white wine for an hour before being immersed in black tea. Although stains were deeper with white wine than with water, red wine still caused the darkest stains because of a “highly pigmented” substance called chromogen.
Sunita Verma from Sparkle Dental Boutique, Chiswick says “For all those wine drinkers (including me!), giving up wine is not the answer. The best way to avoid yellow, stained teeth is through the daily use of a toothpaste which contains a teeth whitening ingredient and professional teeth whitening with a dentist.”
