Anything that stains a white shirt — like coffee, tea, cola, or red wine — can also stain your teeth. Try to cut back if you drink these every day. And rinse your mouth with water when you’re finished.
Slick on a lipstick or gloss in a shade like cherry red, wine, berry, plum, or rosy pink. The blue-based or pink-based undertones will make any yellowish tones in your teeth less obvious.
