The Short Version
This claim is misleading. While sugary drinks do harm teeth through both sugar-driven decay and acid erosion, the blanket assertion that they are "more harmful" than solid sugary foods is not supported by the best comparative evidence. A 2025 systematic review found solid sugary snacks carried a 3.9-fold caries risk versus only 1.56-fold for sugary beverages. Sticky and chewy sweets can cling to teeth for extended periods, creating prolonged acid attacks. The claim conflates two distinct mechanisms—caries and erosion—without evidence that drinks cause greater total dental harm.
