Xylitol is the latest and greatest sugar substitute, and although it is also a sugar it actually fights tooth decay. The plaque bacteria that cause decay (Strep. mutans) lose the ability to adhere to our teeth when exposed to xylitol, so the plaque is reduced and is more easily cleaned away by brushing and rinsing. This means less decay – in fact, more than 50% fewer cavities have been detected in patients using 4 or more grams of xylitol in divided doses dispersed throughout the day. This sweetener is available in both hard candies and chewing gums – Trident is a commonly available brand of gum (but not all Trident has xylitol, so check the label). The candies tend to be less easy to find, but can be special ordered (Google “xylitol candy”). Some patients have digestive problems when using large amounts of xylitol, so go easy in the beginning and see how it affects you. If you are cavity prone, then maintaining good oral health requires you to make wise decisions about your diet (low sugar, no soda, etc.), take good care of yourself (brush and floss), and have regular checkups so your problems can be diagnosed early and nipped in the bud. And now you have another weapon to fight decay – xylitol. It’s almost too easy – but don’t dismiss it just because it’s cheap and tasty – it’s actually good for you!
