A gum disease is a problem that afflicts one in seven people under 50 and one in three over 50. Gum disease can lead to the loss of bone around the teeth and cause pockets to develop between the teeth and gum's. Don't worry because the Japanese researchers found that people who ate just 2 ounces of yogurt per day (about one-third of a serving) nearly halved their risks of advanced gum disease, which begins with gingivitis, or inflammation around the gum's. Brush, floss and eating yogurt can avoid getting a gum disease. Yogurt's lactobacilli bacteria (the good type) feed on sugar and make lactic acid attacks the disease-causing bugs, the experts say. Better start consume yogurt now if you want to have a healthy teeth and gum's.
