When you eat sugary foods or drinks, some of the sugar is deposited in your teeth. This serves as food for the bacteria present in the oral cavity in a natural way, and favors their development and the formation of dental biofilm.
Over time, dental biofilm can damage the enamel, causing what is known as tooth decay. The more sugar the oral bacteria gets, and the poorer the oral hygiene, the greater the harmful effectsnot only on the teeth, but also on the gums.
