Cavities are a serious problem among Americans, particularly those 55 years and wiser. Statistics estimate that about 9 in 10 adults ages 20-64 have at least 1 cavity (i). This sobering statistic seems to be fueled by poor dietary choices, with the typical Western diet high in added sugar and high fructose corn syrup. The good news: Better food choices may reverse this trend, leading to stronger and healthier teeth. Specifically, a new study indicates that probiotics may help to prevent cavities. Probiotics are most commonly found in yogurt, kefir, kimchee, kombucha, and also in specially formulated probiotic supplements.
