So how, exactly, is dark chocolate good for your teeth? There's a bacterium in your mouth called oral streptococci, which produces acid that eats away at your tooth enamel. The antioxidants in dark chocolate prevent the bacteria from turning into damaging acids by acting as a sort of antibacterial compound. Also, the cocoa butter coats your teeth and prevents plaque from sticking to them.
Because chocolate has tons of antioxidants (about four times that of green tea), it can not only inhibit the production of plaque but also reduce inflammation in the body and work to prevent periodontal disease, a symptom of which is swelling of the gums. The bacteria associated with periodontal disease can also enter the bloodstream and cause heart disease and other cardiovascular problems, so periodically consuming dark chocolate is beneficial to your heart health as well.
It's important to remember, however, that munching on a piece of dark chocolate is not like downing a plateful of veggies. It has some important health benefits, but it's far from a healthy food. Like any confection, dark chocolate should be consumed in moderation. It still contains ample amounts of sugar and fat, each of which comes with its own set of health issues. Also, like all chocolates, dark chocolate isn't exactly low in calories. The recommended intake is 1 ounce per day, which is equal to about six Hershey Kisses (don't worry, they're available in a dark variety). Even this small amount, however, contains as many as 150 calories, and since it tastes so good, it's hard not to indulge.
So get your hands (and teeth) on some dark chocolate today to enjoy what is arguably the most delicious but still beneficial food on the planet. Just remember to practice portion control so the health risks associated with an expanding waistline don't overshadow the benefits to your pearly whites.
