Fact & Myth

Sugar is the major cause of cavities

The fact is the acid produced by bacteria in your mouth causes cavities. However the bacteria eat carbohydrates which are present in sugar. Along with sugar; rice, bread, potatoes, fruits and vegetables are also carbohydrates. The bacteria produce acids when you eat anything with carbs.

Once the bacteria are produced, they continue to metabolize carbs and produce acids. This increases the cavities. The amount of carbohydrates that you consume doesn’t cause tooth decay but the duration for which your teeth are exposed to it. Consuming sugary things all day long is bad for your teeth.
