For dental caries to develop in dentine, which dietary component is necessary?

The development of dental caries in dentine is closely linked to the presence of simple carbohydrates in the diet. Simple carbohydrates, such as sugars found in candies, soft drinks, and even some fruits, can easily be fermented by the bacteria present in dental plaque. This fermentation process leads to the production of acids that demineralize both enamel and dentine. When the acid levels are sustained over time due to frequent intake of these carbohydrates, the protective minerals in the hard tissues of the teeth are lost, resulting in the formation of cavities.

Dentine, being softer and more porous than enamel, is particularly susceptible to these acid attacks, making simple carbohydrates a crucial component in the initiation and progression of caries. Monitoring and regulating the intake of simple carbohydrates is therefore a significant aspect of dental health care to prevent caries development.

Other dietary components, such as polysaccharides, may also influence dental health, but simple carbohydrates are primarily responsible for facilitating the acidic environment that leads to cariogenic effects in dentine.
