Sorry to ruin your next backyard BBQ party, but those sticky red sauces that turn everything delicious are cavities waiting to happen. “Barbecued meats, like spare ribs, are some of the worst foods for teeth because of the caramelized sugars used in the sauce,” explains Frederick Baker, DDS. “You have the potential to crack your teeth on parts of the meat that may have over-caramelized, and the extra sugar is never good.”
