Sorbitol is a sugar alcohol commonly used as a low-calorie sweetener in sugar-free gums, candies, and oral care products. It has a lower potential to cause tooth decay than sugar because it is less fermentable by oral bacteria. However, sorbitol is not completely non-cariogenic, as some bacteria can metabolize it, producing acids that may erode enamel. Compared to xylitol, sorbitol is less effective at preventing cavities but still offers oral health benefits when used in moderation. Incorporating sorbitol in dental products helps reduce sugar intake and supports oral hygiene, making it a valuable ingredient in modern dental care.
