What type of dietary habit can contribute to the progression of dental caries?

A high-sugar diet is strongly linked to the progression of dental caries. Sugars provide a readily available source of energy for oral bacteria, particularly Streptococcus mutans, which thrive on these carbohydrates. When these bacteria metabolize sugars, they produce acid as a byproduct. The acids can then demineralize tooth enamel, leading to the formation and advancement of carious lesions.

Frequent consumption of sugary foods and beverages can create an acidic environment in the mouth, especially when oral hygiene practices are not maintained, allowing plaque to build up and further contributing to the progression of cavities. Therefore, a diet high in sugar is a significant risk factor for developing and worsening dental caries.

In contrast, other dietary habits such as high-fiber, low-fat, and low-carb diets do not inherently promote the same rapid progression of dental caries, making them less of a concern in the context of tooth decay.
