Gum-Chewers Have Reason to Smile About Xylitol

Saturday, February 6th, 2010

In the eighties, artificial sweeteners in blue and pink packets, diet soda and sugar-free gum set the standard as “healthy” alternatives to their sugar-laden parent products. Today, there’s another sweetener called xylitol touting sweet-as-sugar taste that is low in calories, and studies show it may help reduce and prevent cavities.

A natural sweetener found in plants and fruits, xylitol was approved by the Food and Drug Administration (FDA) in 1986 as a food additive and is now appearing in sugar-free gum, mints and toothpaste.

Research confirms that of all factors studied, xylitol most likely inhibits the growth of Streptococcus mutans, the oral bacteria that causes cavities, according to Allen Otsuka, PhD, one author of a study in the July/August 2002 issue of General Dentistry, the clinical, peer-reviewed publication of the Academy of General Dentistry (AGD).

Are You Biting Off More Than You Can Chew?

Wednesday, February 3rd, 2010

In our fast-paced lives, many of us may be eating in a hurry, taking giant bites of our food to get done quickly and on to the next task. Fast-food restaurants advertise giant burgers and sandwiches as a selling point, but often those super-sized delicacies are larger than a human mouth.

Taking bites that are too big to chew could be bad for your jaw and teeth, says the Academy of General Dentistry (AGD), an organization of general dentists dedicated to continuing education. At particular risk are people with temporomandibular joint disorder (TMD), which can restrict the range of acceptable bite size. “People with TMD need to avoid opening their mouths too wide,” says AGD spokesperson Barbara A. Rich, DDS, FAGD. “Taking large bites of food can aggravate their condition.” So, smoosh that hoagie before taking a bite.

Dr. Rich also cautions against biting into hard candies, which can chip teeth. Even apples can cause problems. “If you need to open your mouth more than feels comfortable to take a bite, then you should cut the item into smaller portions that are easy to chew,” Dr. Rich says.

People should always avoid chewing ice, popcorn kernels and opening nuts with their teeth, which can lead to chipping and breakage of natural teeth and restorations.
