Something to Chew On: Keeping Those Pearlies Healthy


WebMD Health News

March 26, 2001 (Bethesda, Md.) -- Dental care has come a long way from the days of George Washington, when our first president struggled with custom-rigged ivory dentures after losing his teeth to disease.

A surgeon general's report last year noted that our nation's oral health is its best ever. Tooth disease, called dental caries by dentists and other experts, has declined significantly in terms of both numbers and severity.

"We feel that people should be able to retain their teeth for their lifetime," Dushanka Kleinman, DDS, deputy director of the National Institutes of Health's (NIH's) National Institute of Dental and Craniofacial Research, tells WebMD. "There is no reason to lose a tooth due to dental caries."

But in too many cases, bacteria are still often able to work their way underneath dental enamel and rot teeth away. Many poor and minority groups still suffer untreated tooth disease, and effective prevention and treatment actions don't get fully used.

"We know how to prevent this disease," Alice Horowitz, PhD, senior scientist at the dental institute, tells WebMD. "Children born now needn't have this, even though they do."

Tooth decay is five times as common as asthma and seven times as common as hay fever in 5- to 17-year-olds, and 78% of 17-year-olds have experienced tooth decay.

This week, dental experts are meeting at the NIH to discuss the latest research and offer recommendations. On Wednesday, an independent panel will close the conference by releasing a statement that outlines the best ways to prevent and treat dental caries.

According to the researchers, prevention is most easily achieved through exposure to fluoride.

"Fluoride exposure through water supplies or supplemental tablets should be recommended for all children as a primary preventive measure," says Norman Tinanoff, DDS, at the University of Maryland Dental School in Baltimore. "Perhaps the next best method is daily use of a fluoridated toothpaste."

About 100 million Americans don't have community water fluoridation, although 144 million (62% of the population) do receive this public health benefit. Federal officials hope to increase this proportion to 75% by 2010.

Another key prevention move is having your dentist apply dental "sealant," a plastic film that coats the chewing surfaces of teeth. The sealant prevents decay from sprouting in the nooks and crannies of teeth, where fluoride is less effective on food debris and bacteria.

Sugar was a primo dental health villain back when fluoridation wasn't as widespread. But sugar consumption in this country has been on the rise even as dental caries has declined, notes Brian Burt, PhD, of the University of Michigan School of Public Health in Ann Arbor.

That doesn't mean reach for the sweets, but Burt said that if an individual has strong exposure to fluoride, sugar is a "moderate-to-mild" risk factor, "not the most crucial aspect" of prevention.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.

You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Toothbrush bristles alone cannot clean effectively between these tight spaces. Flossing removes up to 80% of the film that hardens to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Aim for 3 more days!
