Nobody anticipates creating a cavity drilled and filled by the dentist. Now there’s an alternative solution: an antimicrobial liquid that may be brushed on cavities to stop tooth decay – painlessly.

The liquid is known as silver diamine fluoride, or S.D.F. It’s been used for decades in Japan, but it’s been available in america, under the brand name Advantage Arrest, for merely a year.

The meals and Drug Administration cleared silver diamine fluoride for use being a tooth desensitizer for adults 21 and older. But studies show it can halt the growth of cavities and prevent them, and dentists are increasingly utilizing it off-label for anyone purposes.

“The upside, the fantastic one, is basically that you don’t need to drill and you don’t need an injection,” said Dr. Margherita Fontana, a professor of cariology at the University of Michigan.

Silver diamine fluoride is already utilized in countless dental offices. Medicaid patients in Oregon are experiencing the treatment, and a minimum of 18 dental schools have started teaching the next generation of pediatric dentists utilizing it.

Dr. Richard Niederman, the chairman of the epidemiology and health promotion department at the New York University College of Dentistry, said, “Being capable to paint it on in Thirty seconds with no noise, no drilling, is way better, faster, cheaper.”

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

The primary negative thing is aesthetic: Silver diamine fluoride blackens the brownish decay on a tooth. That won’t matter on a back molar or possibly a baby tooth that may drop totally out, however, many patients are likely to be deterred with the prospect of the dark spot on an obvious tooth.

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

A cavity that have being drilled cost $151. The liquid “was very affordable,” Dr. Urschel said.

The noninvasive treatment might be well suited for the indigent, nursing home residents while others who’ve trouble finding care. And many anxious dental patients desire to dodge the drill.

Nevertheless the liquid might be especially a good choice for children. Nearly 1 / 4 of 2- to 5-year-olds have cavities, in accordance with the Cdc and Prevention.

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

“S.D.F. provides for us an opportunity to slow up the amount of toddlers with cavities visiting the O.R.,” said Dr. Arwa Owais, an associate at work professor of pediatric dentistry at 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 holiday to a operating room.

Dr. MacLean said, “People feel that parents will reject it as a consequence of poor aesthetics.” But “if this means preventing a child from needing to be sedated or having their tooth drilled and filled, there are several parents who enjoy 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 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 occasion, Ms. Bujeiro said, she’d choose silver diamine fluoride. “I would use it in baby teeth even if it’s in-front,” she said. When it comes to discoloration? “You can’t see it an excessive amount of.”

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 following the first markedly arrests cavities, research indicates.

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

Fillings, by comparison, tend not to cure an oral infection.

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

That’s why some children will need to have Dentist under anesthesia twice.

Bacterial infections also cause acne, but a “dermatologist doesn’t take a scalpel and stop 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.
