Nobody looks forward to creating a cavity drilled and filled with a dentist. Now there’s a different: an antimicrobial liquid that may be brushed on cavities to prevent dental cairies – 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 United States, within the brand name Advantage Arrest, for nearly annually.

The meals and Drug Administration cleared silver diamine fluoride to be used like a tooth desensitizer for adults 21 and older. But research has shown it could halt the continuing development of cavities and stop them, and dentists are increasingly using it off-label for all those purposes.

“The upside, the fantastic one, is basically that you don’t have to drill so 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 hundreds of dental practices. Medicaid patients in Oregon are getting treatments, and at least 18 dental schools have started teaching generation x of pediatric dentists using it.

Dr. Richard Niederman, the chairman of the epidemiology and health promotion department with the New York University College of Dentistry, said, “Being capable of paint it on in 30 seconds without any noise, no drilling, is better, 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 will not matter with a back molar or possibly a baby tooth that can fallout, but some patients are probably be deterred from the prospect of an dark i’m all over this a visible tooth.

Until more insurers get it, patients also have to cover the fee. Still, it’s affordable. Dr. Michelle Urschel, an anesthesiologist, was very happy to pay $25 to get Dr. Jeanette MacLean, a pediatric dentist in Glendale, Ariz., paint over a cavity that her son Knox, 4, had recently developed.

A cavity which had to become drilled cost $151. The liquid “was very economical,” Dr. Urschel said.

The noninvasive treatment could be ideal for the indigent, elderly care residents among others that have trouble finding care. And a lot of anxious dental patients want to dodge the drill.

However the liquid could be especially a good choice for children. Nearly 25 % of 2- to 5-year-olds have cavities, according to the Centers for Disease Control and Prevention.

Some preschoolers with severe cavities have to be treated in the hospital under general anesthesia, although it may pose risks towards the developing brain.

“S.D.F. provides a chance to limit the quantity of toddlers with cavities visiting the O.R.,” said Dr. Arwa Owais, an associate at work 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 wished to delay a trip to the operating room.

Dr. MacLean said, “People believe that parents will reject it as a result of poor aesthetics.” But “if this means preventing a kid from being forced to be sedated or having their tooth drilled and filled, there are lots of parents who choose S.D.F.,” she added.

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

Two front teeth, however, were drilled. The very next time, Ms. Bujeiro said, she’d go for silver diamine fluoride. “I would use it in baby teeth even though it’s in-front,” she said. Are you aware that discoloration? “You can’t see it excessive.”

Silver diamine fluoride has an additional over traditional treatment: It kills the bacteria that can cause decay. An additional treatment applied six to 18 months after the first markedly arrests cavities, research has shown.

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

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

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

That’s why some children have to have broken tooth under anesthesia twice.

Microbe infections also cause acne, however a “dermatologist doesn’t please take a scalpel and cut 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 carries a Facebook page called SDF Action, where dentists can discuss individual cases.
