The document discusses the role of carbohydrates in dental caries (tooth decay). It states that fermentable carbohydrates like glucose, fructose, and sucrose are easily fermented by bacteria like Streptococcus mutans in dental plaque, producing acids that demineralize tooth enamel and lead to cavities. Frequent sugar intake and sticky carbohydrates increase caries risk as they prolong acid exposure. Starches carry less risk as they are slowly broken down. Replacing sucrose with non-fermentable alternatives like sorbitol and xylitol reduces caries.
