While we may think sugar itself is the component that leads to tooth decay, that’s actually not the case. The dangers of sugar come from the reaction that occurs when they interact with certain types of bacteria in your mouth.
There are both good and bad bacteria in the mouth, and it’s the bad bacteria that reacts with the sugar in a way that leads to tooth decay, according to Healthline. When sugar enters the mouth, it serves as a catalyst, sparking a chemical reaction with cariogenic oral bacteria that create acids that damage tooth enamel.
Since enamel is the protective layer over our teeth, any damage to it leads to tooth decay and permanently damaged teeth. If cavities and decay are not addressed, it can cause pain and potential tooth loss, which can have ramifications of its own.
