Dental Health Myth #1: The More Sugar You Eat, The Worse It is For Your Teeth
Yes, sugar can cause cavities on your teeth. However, having tooth cavities is not much about the amount of sugar you consume, but how long it stays in your mouth.
Sugar creates acid that wears away the enamel of your tooth. So, if sugar stays longer in your mouth, the more it produces acid and the more chances your teeth will have cavities. Thus, after eating sugary food, you should brush your teeth or rinse your mouth with water or mouthwash.
