Why do lollies cut your tongue?

Lollies can cut your tongue primarily due to their sharp edges and hard texture, especially if they are broken or have been bitten into. The sugar content can also exacerbate any irritation caused by the abrasion. Additionally, certain ingredients in lollies, like citric acid in sour varieties, can irritate sensitive areas in the mouth. Always be cautious when consuming hard candies to avoid injury.
