Nobody anticipates creating a cavity drilled and filled by the dentist. Now there’s an alternate: an antimicrobial liquid which can be brushed on cavities to stop cavities – painlessly.

The liquid is termed silver diamine fluoride, or S.D.F. It’s been used for decades in Japan, but it’s been obtainable in america, underneath the manufacturer Advantage Arrest, for nearly 12 months.

The Food and Drug Administration cleared silver diamine fluoride to use like a tooth desensitizer for adults 21 and older. But research has revealed it might halt the progression of cavities and prevent them, and dentists are increasingly deploying it off-label for those purposes.

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

Silver diamine fluoride has already been used in countless dental practices. Medicaid patients in Oregon increasingly becoming treatments, and a minimum of 18 dental schools have started teaching the next generation of pediatric dentists how to use it.

Dr. Richard Niederman, the chairman from the epidemiology and health promotion department with the Nyc University College of Dentistry, said, “Being capable of paint it on in Half a minute with no noise, no drilling, is much better, faster, cheaper.”

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

The primary bad thing is aesthetic: Silver diamine fluoride blackens the brownish decay over a tooth. That will not matter over a back molar or a baby tooth that will drop out, however, many people are likely to be deterred through the prospect of the dark just right an obvious tooth.

Until more insurers buy it, patients also need to cover the cost. Still, it’s relatively inexpensive. 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 be drilled cost $151. The liquid “was very affordable,” Dr. Urschel said.

The noninvasive treatment might be perfect for the indigent, elderly care residents yet others that have trouble finding care. And lots of anxious dental patients want to dodge the drill.

Though the liquid might be especially helpful for children. Nearly one fourth of 2- to 5-year-olds have cavities, in line with the Cdc and Prevention.

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

“S.D.F. gives us a chance to limit the variety of toddlers with cavities going to the O.R.,” said Dr. Arwa Owais, a part 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 assume that parents will reject it due to poor aesthetics.” But “if this means preventing a youngster from being forced to be sedated or having their tooth drilled and filled, there are lots of parents they like S.D.F.,” she added.

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

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

Silver diamine fluoride has an additional benefit over traditional treatment: It kills the bacteria that induce decay. Another treatment applied six to 18 months following your first markedly arrests cavities, studies have shown.

“S.D.F. decreases the incidence of the latest caries and progression of current caries by about 80 percent,” said Dr. Niederman, who’s updating an evidence overview of silver diamine fluoride published in 2009.

Fillings, in comparison, do not cure a dental infection.

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

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

Transmissions also cause acne, however a “dermatologist doesn’t require 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 has a Facebook page called SDF Action, where dentists can discuss individual cases.
