Here’s a problem you may have had: out for dinner, and you just finished off a glass of red wine. You go to smile, and you see their eyes dart down to your teeth, a flicker of disappointment crossing their eyes. Either there’s a bit of spinach stuck in your teeth, or–if you had the slow-roast lamb–your teeth may become stained an off-purple by that wine you just drank. While it’s known that drinks like coffee and wine can stain teeth, they don’t usually have such a fast effect.
It’s happened to everyone. No matter what preparations we take or how we try to mitigate the effects, red wine is one of the worst offenders for staining your teeth.
