Xylitol has specific properties that make it indigestible to bacteria which helps to decrease the number of bacteria and reduces the instances of cavities.

The American Academy of Pediatric Dentistry recommends 3 to 8 grams to reach the maximum benefits.

Xylitol can be found in gum, mints and candies, as a sugar substitute and syrups.

While xylitol is considered an option for fighting cavities there are also conflicting studies. Because xylitol is natural does not mean it is unprocessed. It is highly processed. Xylitol is also not calorie free. It is not sugar free but contains 40% fewer calories than sugar. It can still affect blood glucose levels unlike sweeteners like stevia. For some people xylitol can cause gastrointestinal issues. It may cause gas, bloating or diarrhea. It is advised that people with IBS avoid xylitol.

Xylitol is very dangerous for pets. It is important that you keep it away from pets and do not offer them food made with this sweetener. Xylitol can affect your dogs ability to produce insulin which can cause hypoglycemia or liver failure.

While xylitol may be helpful in preventing cavities it is not the only option. Xylitol is just one part of what should be a multi-faceted approach to dental hygiene. Chewing sugar free gum will not replace brushing your teeth but can be helpful for overall dental health.
