Bacteria located on the surface of the teeth use the sugars as a food source and through anaerobic fermentation, create lactic acid. This lowers the pH near the surface of the tooth, which slowly erodes the calcium hyrdoxyappetite crystals of the tooth. This may expose underlying layers, such as the dentin, to bacteria. This can lead to an infection of the tooth and require a root canal, extraction, or filling.
