Nobody looks forward to creating a cavity drilled and filled by a dentist. Now there’s an alternative solution: an antimicrobial liquid which can be brushed on cavities to halt tooth decay – painlessly.

The liquid is called silver diamine fluoride, or S.D.F. It’s been utilized for decades in Japan, but it’s been obtainable in the us, within the manufacturer Advantage Arrest, for merely annually.

The Food and Drug Administration cleared silver diamine fluoride for use being a tooth desensitizer for adults 21 and older. But research has shown it might halt the growth of cavities and stop them, and dentists are increasingly deploying it off-label for all those purposes.

“The upside, the truly great one, is that you simply don’t need to drill and also you don’t require an injection,” said Dr. Margherita Fontana, a professor of cariology with the University of Michigan.

Silver diamine fluoride is found in numerous dental practices. Medicaid patients in Oregon are receiving the therapy, and at least 18 dental schools have begun teaching generation x of pediatric dentists using it.

Dr. Richard Niederman, the chairman in the epidemiology and health promotion department with the Ny University College of Dentistry, said, “Being capable to paint it on in Thirty seconds without noise, no drilling, is best, faster, cheaper.”

“I would encourage parents to ask about for it,” he added. “It’s less trauma for that kid.”

The principle bad thing is aesthetic: Silver diamine fluoride blackens the brownish decay with a tooth. That may not matter with a back molar or a baby tooth that will drop out, however, many patients are apt to be deterred from the prospect of your dark spot on a visible tooth.

Until more insurers pay for it, patients should also cover the fee. Still, it’s comparatively cheap. Dr. Michelle Urschel, an anesthesiologist, was thrilled to pay $25 to have Dr. Jeanette MacLean, a pediatric dentist in Glendale, Ariz., paint more than a cavity that her son Knox, 4, had recently developed.

A cavity that had to get drilled cost $151. The liquid “was very reasonable,” Dr. Urschel said.

The noninvasive treatment could possibly be suitable for the indigent, elderly care facility residents among others that have trouble finding care. And several anxious dental patients need to dodge the drill.

But the liquid could possibly be especially helpful for children. Nearly 25 % of 2- to 5-year-olds have cavities, based on the Cdc and Prevention.

Some preschoolers with severe cavities must be treated inside a hospital under general anesthesia, although it may pose risks on the developing brain.

“S.D.F. gives us a way to decrease the amount of toddlers with cavities exploring O.R.,” said Dr. Arwa Owais, an affiliate professor of pediatric dentistry with the University of Iowa.

Dr. Laurence Hyacinthe, a pediatric dentist in Harlem, used silver diamine fluoride on eight uncooperative children whose parents desired to delay a holiday to a operating room.

Dr. MacLean said, “People assume that parents will reject it as a consequence of poor aesthetics.” But “if it implies preventing a child from the need to be sedated or having their tooth drilled and filled, there are several parents they like S.D.F.,” she added.

Alejandra Bujeiro, 32, was delighted that her 3-year-old daughter, Natalia, didn’t require two cavities completed the back of her mouth. Instead Dr. Eyal Simchi, a pediatric dentist in Elmwood Park, N.J., brushed silver diamine fluoride around the decay.

Two front teeth, however, were drilled. The next time, Ms. Bujeiro said, she’d opt for silver diamine fluoride. “I would apply it in baby teeth regardless of whether it’s in the front,” she said. When it comes to discoloration? “You can’t notice too much.”

Silver diamine fluoride has an additional advantage over traditional treatment: It kills the bacteria that induce decay. An extra treatment applied six to Eighteen months after the first markedly arrests cavities, research has shown.

“S.D.F. reduces the incidence of the latest caries and growth of current caries by about Eighty percent,” said Dr. Niederman, who is updating an evidence writeup on silver diamine fluoride published during 2009.

Fillings, in comparison, don’t cure a verbal infection.

“There’s nothing which goes on in a operating room that treats the main problem,” said Dr. Peter Milgrom, a professor of pediatric dentistry with the University of Washington who was simply instrumental in receiving F.D.A. clearance for silver diamine fluoride and it has a monetary stake in Advantage Arrest.

That’s why some children should have braces dental trauma under anesthesia twice.

Bacterial infections also cause acne, but a “dermatologist doesn’t take a scalpel and take off your pimples,” said Dr. Jason Hirsch, a pediatric dentist in Royal Palm Beach, Fla. Yet “that’s how dentistry has approached cavities.” Dr. Hirsch includes a Facebook page called SDF Action, where dentists can discuss individual cases.
