Q: I noticed that Sorbitol is listed in my toothpaste’s ingredients. Isn’t that a kind of sugar?
A: Sorbitol is a sugar alcohol made from plant-based carbohydrates broken down through chemical processing. That means it’s not actually sugar, so manufacturers add it to toothpastes to create a sweet flavour without leading to tooth decay. Because oral bacteria can not metabolize sorbitol, it is not converted to cavity-causing acids and, therefore, the teeth are protected. As an added bonus it also helps to relieve dry mouth by it’s ability to draw in water.
