Why does red wine stain my teeth?
The primary cause of stained teeth from red wine results from these things called “chromogens”. These are pigment-producing substances abundant in red wine that sticks onto dental enamel. Tannins in red wine and drinks we consume, also enhance the possibility of chromagens binding to the teeth, leaving unattractive stains.
Drink some sparkling water in between tastings or multiple glasses of red wine. The bubbles will loosen up and scrub away the stains and prevent you from being carried out of the restaurant or wine tasting establishment.
