Children living in counties with fluoridated water have significantly less tooth decay than those living in counties that lack water fluoridation programs, according to a newly published large-scale study.
Reduced decay rates were most pronounced in the primary teeth of children living in fluoridated counties. Yet community water fluoridation (CWF) also was credited with conferring a meaningful level of protection to the permanent teeth of children and adolescents. Continue reading
The good news: In recent years, tooth decay rates have significantly decreased for American children.
Overall, 43.1 percent of American children between the ages of 2 and 19 experienced decay in primary and permanent teeth in 2015-16, down from 50 percent reported in 2011-12. Continue reading
Every five years, the federal government comes out with a new edition of its dietary guidelines. The official nutritional recommendations help shape America’s school lunch menus, influence grocery shopping trends, and of course, generate a flurry of news coverage.
The big question for reporters – and their readers, listeners and viewers is always “what’s new?” Continue reading
Baltimore Sun reporter Andrea McDaniels was surprised to learn about an off-label treatment for tooth decay that some dentists are using.
In the fight against decay-causing bacteria, some researchers call the agent, silver diamine fluoride, a “silver-fluoride bullet.”
They point to evidence suggesting that SDF is not only effective in halting the decay process but in preventing the development of new caries. The material is cheap and can be easily painted onto the affected tooth.
In this Q&A, McDaniels tells us more about her work on the story, and offers some insights into how she manages her busy health and medical beat at the Sun.

Scientists studying a decayed lesion within an ancient wisdom tooth say they have discovered the earliest known evidence of dentistry.
The cavitated third molar belonged to a young man said to have lived and died in Northern Italy during the Late Upper Paleolithic era.
Images from inside the 14,000-year-old tooth, obtained using scanning electron microscopy, disclosed a pattern of chipping and striations that researchers say were made using a tiny stone pick. Continue reading
