The sugar content in the food you eat has a big effect on your teeth and gums. Acid that attacks the teeth is produced when bacteria (plaque) come into contact with sugar in the mouth. This can eventually result in tooth decay which is why drinking sugar-filled sodas, sweetened fruit drinks, and non-nutritious snacks takes a toll on teeth. Even foods such as milk and vegetables that have important nutrients that are important in our diet, contain sugar. To help control the amount of sugar you consume, read food labels and choose foods and beverages that are low in added sugars.
