Red Wine

The color of red wine, known as chromogens, includes all of the heart-healthy compounds, but it also discolors your teeth. Red wine chromogens will stain your teeth brown. In reality, one research compared the stains left by coffee and wine after whitening and discovered that red wine discolored teeth substantially more than coffee.

Not only that, red wine is rich in acidity. This acid can nibble away at tooth enamel, turning teeth yellow. Teeth without protective enamel are vulnerable to germs and deterioration. If you want to have a bright white smile, limit your red wine as much as possible.
