When it comes to less-than-pearly whites, coffee’s not the only culprit. Watch out for these little-known teeth tainters, says Cynthia Sherwood, DDS, a spokeswoman for the Academy of General Dentistry:
It’s actually more acidic than red—and acid breaks down tooth enamel, making it more likely to absorb color from food or drinks. That means if you drink white wine while enjoying, say, a plate of berries, your teeth are at risk. No need to nix the vino entirely; just alternate with sips of water to avoid unsightly marks.
Orange Juice
Also acidic, it’s especially damaging when paired with a dark beverage (like coffee). Daily cups of OJ can also leave your mouth more prone to stains because the acid continues to break down enamel over time. Lower the acidity level a little (and save calories) by diluting your juice with water or seltzer.
If you’re a competitive swimmer or swim for hours each week, you could end up with spots called “swimmer’s calculus.” The high pH of the chemicals in the pool water causes proteins to harden into a dark brown tartar. You’ll probably need to get your teeth professionally cleaned three or four times per year.
