Yogurt may take the bite out of gum disease

Regularly eating yogurt and other foods with lactic acid may be good for mouth, Japanese researchers report on Journal of Periodontology. They found that consuming yogurt and lactic acid drinks was significantly associated with better periodontal health, whereas milk and cheese were not. Periodontal disease is a chronic bacterial condition associated with receding gums and tooth loss in adults. Outside of regular brushing and flossing, effective measures to allay this disease are limited.
