Which sugar alcohol is commonly used in chewing gums?

Xylitol is commonly used in chewing gums due to its beneficial properties for dental health. It has been shown to reduce the risk of cavities by inhibiting the growth of bacteria that cause tooth decay. Xylitol is not fermentable by these bacteria, which means it does not produce acids that can harm tooth enamel. Additionally, xylitol contributes to saliva production, which helps to neutralize acids in the mouth and maintain a healthy pH level.

While other sugar alcohols like sorbitol, mannitol, and erythritol may also be used in various food products, they do not have the same strong evidence supporting their benefits for oral health. Sorbitol is often found in sugar-free products but is less effective than xylitol in promoting dental benefits. Mannitol is used more in medical settings and dietary supplements, whereas erythritol is known for being lower in calories and often used in baked goods and confections, but again, it lacks the specific dental advantages that xylitol provides. Therefore, xylitol stands out as the preferred choice in chewing gums due to its protective effects on teeth.
