MYTH: Sugar causes cavities

FACT: Cavities are actually caused by acidic foods and drinks that wear away the enamel on your teeth.
事实：蛀牙实际上是由酸性食物和饮料导致的,酸性物质会腐蚀牙齿上的釉质.
"Sugar isn't the cause of tooth decay; acid is," Dr. Mark Burhenne, of the online "Ask a Dentist" community, said. "The most cavity-causing food is crackers and breads, not candy. When you eat something with sugar, bacteria that naturally reside in your mouth consume this sugar as well. Bacteria's waste product is acid, so after they have a meal, they excrete acid....Acid decalcifies or demineralizes tooth enamel by taking away its structure, creating decay."
"问牙医"网络社区的马克•布尔亨内医生说："导致蛀牙的不是糖,而是酸.最容易导致蛀牙的食物是饼干和面包,不是糖.当你吃含糖食物时,口腔内的天然细菌也在'吃糖'.细菌排出的废物是酸,所以在吃完饭后,细菌都会产生酸……这些酸性物质会腐蚀牙齿的外结构,从而使牙釉质脱落,导致蛀牙."
