@realbehindthechair: You've been lied to! Sugar doesn't directly hurt your teeth... but it feeds the monsters that do. Millions of bacteria live in your mouth, and they have a massive sweet tooth. When you eat candy, you're throwing them a buffet. After they feast on the sugar, they excrete a highly toxic, corrosive acid directly onto your teeth. Yes, they are literally pooping acid! This biological "acid rain" sizzles and melts away your indestructible enamel, creating a deep crater—a cavity.
