Chocolate can actually be good for your teeth! Yes, you read that correctly — chocolate can prevent tooth decay. However, not every kind of chocolate is dental dynamite. The cocoa bean is what houses the good stuff — not the chocolate itself — so the closer the confection is to the bean, the better.
Cocoa beans contain tannins, polyphenols and flavonoids, each of which is a type of strong antioxidant that benefits your mouth and teeth. Tannins are what give dark chocolate it’s slightly bitter taste and are responsible for the sweet’s dark pigments. More importantly, they help prevent cavities by inhibiting bacteria from sticking to your teeth. Polyphenols limit the effects of bacteria, meaning they work to neutralize the microorganisms that cause bad breath, prevent infections in your gums and battle tooth decay. Flavonoids work to slow tooth decay, among other things.
Of the three kinds of chocolate (dark chocolate, milk chocolate and white chocolate), dark chocolate is the least processed and closest to the cocoa bean, which makes it the healthiest option of the three. For best results, the chocolate should be around 70 percent cocoa. Hershey’s Extra Dark Chocolate contains 60 percent cocoa, so it’s a pretty good choice, but Ghirardelli’s Twilight Delight is a better option at 72 percent. Other bars are even more beneficial, such as Ghirardelli’s Midnight Reverie and Lindt’s Cocoa Supreme Dark, which contain 86 and 90 percent cocoa, respectively. You should be able to find tooth-friendly dark chocolate at your local grocery store, and many bars advertise their cocoa percentage clearly on the label. Also, in case you needed another perk, dark chocolate contains less sugar than other varieties, so it’s slightly better for your waistline, too.
