Dr. Richard Parsanko runs Sonoran Desert Dentistry in Scottsdale, Arizona. Here, he explains how xylitol, a sugar found in some candy and chewing gums, could benefit your teeth.
What is xylitol? Xylitol is a naturally occurring sugar substitute found in certain fruits, vegetables, berries, and mushrooms, as well as corn. It is white, and looks and tastes like sugar. In the United States, it has been used in foods since the 1960s, and some other countries use it in medicine, such as a sugar substitute for diabetics. In terms of chemistry, it is actually a sugar alcohol, not a sugar.
How does xylitol work to benefit your teeth? Xylitol causes an increase in salivation. The saliva in your mouth is like a car wash: It washes the plaque and food off your teeth. But saliva also has antibodies, and by increasing those, you get a healthier mouth.
What products contain xylitol? Certain candy, mints, and chewing gum contain xylitol. These products are always clearly marked. The best part is that along with being good for you, xylitol is sweet and actually tastes good. Xylitol can also be used as an antibacterial nasal spray.
How often should you consume xylitol? Studies show that supplementing a normal diet with regular consumption of xylitol (such as chewing gum with xylitol about twice a day) is beneficial to your teeth. Consuming about 4 to 12 grams per day is the most effective frequency.
Do certain foods contain xylitol? In the United States, xylitol is used as a food additive for foods with special dietary purposes. Research also shows that the use of xylitol-sweetened foods provides additional help in the battle against tooth decay by significantly decreasing plaque accumulation.
How does xylitol interact with fluoride? Research also shows that xylitol and fluoride act synergistically to increase the effectiveness of oral hygiene products. Regular use of fluoride toothpaste and fluoridated water (most major cities add fluoride to their tap water) is recommended for cavity prevention, because it strengthens the surface and internal structure of your tooth enamel, resulting in 30% to 60% fewer cavities.
Who is the most at risk for tooth decay and should therefore get extra amounts of xylitol? Individuals who are at high risk for tooth decay include those who have exposed root surfaces, suffer from xerostomia (dry mouth), oral cancer survivors, diabetics, and anyone suffering from a compromised immune system. By sucking on xylitol gum or candy, rather than other sugar-filled products, their risk of decay will decrease.
