Nobody looks forward to having a cavity drilled and filled by a dentist. Now there’s an alternative: an antimicrobial liquid that can be brushed on cavities to stop tooth decay — painlessly.
The liquid is called silver diamine fluoride, or S.D.F. It’s been used for decades in Japan, but it’s been available in the United States, under the brand name Advantage Arrest, for just about a year.
Midlevel ‘dental therapists’ can care for underserved Medicaid patients—but dentists see competition.
Researchers believe there are several mechanisms by which fluoride achieves its anticaries (cavity-preventing) effect. It reduces the solubility of enamel in acid by converting hydroxyapatite into less soluble fluorapatite; it may exert an influence directly on dental plaque, reducing the ability of plaque organisms to produce acid; and it promotes the remineralization of tooth enamel in areas that have been decalcified by acids.
Several published studies have found lasers can often allow patients to skip numbing anesthetic when getting cavities treated. But there's scant evidence showing the lasers provide long-term benefit to teeth, as some dentists claim.
The carnivorous fishes' teeth may be terrifying. But they're also models of oral hygiene.
Dental caries is the most prevalent infectious disease in humans, affecting 97 percent of the population in their lifetime. The result of the disease process known as dental caries, getting cavities is a complex and multifactorial scenario.
The Children's Dental Health Project (CDHP) created these resources to help policymakers, health providers and health advocates advance strategies to both improve children's health and reduce costs. By preventing early tooth decay — or at least managing it — states can improve population health.
