There is a way to prevent tooth decay with sugar. We know bacteria loves sugar and sugar causes cavities, but we can trick these bugs by feeding them a sugar they can’t digest.
Xylitol is just that!
It’s a sugar alcohol, found in some toothpastes, mints and gums. Xylitol has a very effective anti-bacterial effect. The bugs that eat xylitol cannot reproduce effectively; they can’t produce decay-forming acid and they can’t form that sticky layer that helps it attach to tooth surfaces. This means that when you eat more xylitol you get less tooth decay.
Consider this a homeopathic remedy. The more often you use xylitol, the more effective it is. This means using xylitol gums, mints and toothpastes 4 to 5 times a day. The longer the xylitol is in contact with your teeth the more effective it is. Because this actually helps decrease the cavity-causing bacteria, this could likely be more effective than fluoride in preventing tooth decay.
