On the other hand, there is a certain sugar that actually starves the bacteria that cause tooth decay: xylitol, a naturally occurring sugar, can decrease tooth decay. However, there are several things you need to be aware of when using xylitol chewing gum.
- Start with low amounts and work up to the recommended daily dosage.
- Chew gum that contains xylitol as the only sweetener, or at least the main sweetener.
- Chew enough gum to give you at least 5 grams of xylitol per day - ideally 6-10 grams. (That ends up being a lot of gum!)
- Chew the gum after every meal and snack (at least 3 separate doses per day).
Be aware that too much xylitol (4-5 times the regular dose) can cause diarrhea. Although xylitol is safe for children when used in small doses, young children must be monitored closely for possible diarrhea, which could lead to dehydration. Xylitol is safe for humans but can be deadly to dogs. A dog that consumes xylitol should be taken to the Veterinarian immediately.
There are several chewing gums with xylitol as the only or main sweetener. Among them is Spry chewing gum. If you chew this gum to cut down on decay, you need to chew about 7-13 pieces a day. Spry gum is available in San Antonio at Sun Harvest, Whole Foods, Central Market and other local stores. You may also order online at http://www.xlear.com/.
Xylitol is also available online in caramels, mints, lollipops and as a sweetener from Dr. John's Candies at http://www.drjohns.com/. All of Dr. John's xylitol products are labeled with the amount of xylitol contained per serving.
