Something to Chew On: Keeping Those Pearlies Healthy
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.
