What is a key fact about soft drinks?

Soft drinks are known for their high sugar content and acidic nature, both of which significantly contribute to dental decay. When consumed, sugars in soft drinks are metabolized by bacteria residing in the mouth, producing acids as a byproduct. These acids can erode tooth enamel, leading to cavities and other forms of dental decay. The frequent consumption of soft drinks can lead to an increased risk of tooth decay due to this process.

In contrast, while some of the other options might seem appealing, they do not reflect the negative impact of soft drinks on oral health. Soft drinks do not provide essential nutrients, and in fact, they often lack beneficial components found in other beverages like milk or water. They are also generally higher in calories compared to water, not lower, and they do not promote healthy teeth; rather, they can cause harm to dental structures. Thus, the fact that soft drinks contribute to dental decay is critical knowledge for understanding the importance of dietary choices in maintaining oral health.
