Tooth Decay
Tooth decay (dental caries) is the most direct and immediate consequence of excessive sugar consumption. Sugar feeds oral bacteria that produce acid, eroding tooth enamel. While diabetes can result from long-term sugar overconsumption, tooth decay is the primary dental effect.
Sugar feeds the bacteria in the mouth that produce acids, and these acids erode tooth enamel over time, directly causing tooth decay and cavities. This is the most immediate and well-established physical effect of excess sugar consumption, whereas conditions like diabetes and blood pressure changes involve more complex, indirect causal pathways (often tied to obesity and overall diet) rather than sugar alone.
