You probably know that tooth decay results when the bacteria in your mouth release acids after consuming sugars. After you eat sugars, particularly the type of sugar known as sucrose, increased acid in your mouth begins to dissolve the enamel and dentin in your teeth, and you end up with cavities.
What are the Types of Sugars?
Modern diets include several types of sugars. Most of these are fermented by oral bacteria, producing acids that are harmful to teeth.
- Sucrose (commonly known as sugar)
- Glucose (released from starch consumption)
- Lactose (milk sugar) — Less acid is produced from this type of sugar
- Fructose (found naturally in fruit and also added to many processed foods)
Recommended intake of “free sugars” is no more than 10 teaspoons per day. Note that a can of soda contains over 6 teaspoons! Soft drinks are the largest source of sugar consumption in the U.S. In 2003, for example, Americans drank an average of 52 gallons of soft drinks. Average per capita consumption of all sugars in the U.S. was 141.5 pounds (64.3 kg) one of the highest levels in the world.
Sugar substitute xylitol (which is chemically similar to sugar but does not cause decay) can be part of a preventive program to reduce or control tooth decay. Chewing gum sweetened with xylitol stimulates saliva flow and helps protect against decay.
Sugars Released from Starches
Starches are foods like rice, potatoes, or bread. When you eat refined starches, such as white bread and rice, enzymes in your saliva release glucose. However, these foods have a lower potential to produce decay than foods with added sugars. When sugars are added to starchy foods, as in baked products and breakfast cereals, the potential for decay increases.
Less refined starches such as whole grains require more chewing and stimulate secretion of saliva, which protects from harmful acids.
The Case for Fruit
Fresh fruit has not been shown to produce cavities, so it makes sense to eat them instead of sugary desserts and snacks. Dried fruit is more of a problem because the drying process releases free sugars.
You may have seen Kathy Ireland on the cover of Sports Illustrated, but did you know that she is now a business mogul?
Through it all, Ireland has kept her model good looks, and that includes a bright, glowing smile. In a recent interview with Dear Doctor magazine she said that keeping her smile has required ongoing maintenance and more.
It seems that Ireland is a bit of a daredevil. She described a moment of fun with her children when she tried to stand in their wagon and “wagon surf” across her driveway. It ended badly when she crashed into her parked car and suffered a broken nose, split forehead and several broken teeth. “I learned that my love of adventure exceeds my coordination,” she commented.
Ireland was born in Glendale, California in 1963. She demonstrated her drive to succeed early in life, starting at age 4 when she and her sister sold painted rocks from their wagon. Later she had a paper route. She began modeling at 17, with the goal of earning enough to pay for college or to start a business. In her successful modeling career she graced the covers of Glamour, Cosmopolitan, Harper's Bazaar and Sports Illustrated. Her first cover for Sports Illustrated, the publication's 25th Anniversary Swimsuit Edition, was the magazine's best-selling swimsuit issue to date.
In 1993 she founded her marketing and design firm, kathy ireland Worldwide. Now a billion-dollar industry, the firm sells fashions such as wedding gowns and bridesmaid dresses, as well as a wide range of items for home and family.
She has also written a number of books teaching others how to be successful — based on her own experience — as well as three children's books.
Discussing her oral health, Ireland says that she required serious professional assistance on more than one occasion. When she was a child she knocked out a tooth and later knocked it loose again. As an adolescent she wore braces for about three years. After the driveway incident she needed numerous veneers and dental implants to replace a lost tooth and restore her smile.
Her maintenance routine includes regular flossing and brushing, and she has her teeth cleaned every six months. She keeps up on her reading about the latest in research on dental health, and encourages her three children to floss and brush their teeth, to limit eating sweets and to do what they can to avoid injuries to their mouths and teeth.
