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

The liquid is called silver diamine fluoride, or S.D.F. It’s been useful for decades in Japan, but it’s been accessible in the usa, under the brand name Advantage Arrest, for almost 12 months.

The meal and Drug Administration cleared silver diamine fluoride to use like a tooth desensitizer for adults 21 and older. But research shows it may halt the growth of cavities which will help prevent them, and dentists are increasingly utilizing it off-label for the people purposes.

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

Silver diamine fluoride has already been found in hundreds of dental offices. Medicaid patients in Oregon are receiving the therapy, and at least 18 dental schools have begun teaching the next generation of pediatric dentists the way you use it.

Dr. Richard Niederman, the chairman in the epidemiology and health promotion department on the The big apple University College of Dentistry, said, “Being in a position to paint it on in Half a minute without having noise, no drilling, is much better, faster, cheaper.”

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

The key downside is aesthetic: Silver diamine fluoride blackens the brownish decay on a tooth. That may not matter on a back molar or perhaps a baby tooth which will drop totally out, however some patients are probably be deterred from the prospect of a dark just right an apparent tooth.

Until more insurers buy it, patients also have to cover the price. Still, it’s pretty cheap. Dr. Michelle Urschel, an anesthesiologist, was happy to pay $25 to own 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 reasonable,” Dr. Urschel said.

The noninvasive treatment may be ideal for the indigent, elderly care residents yet others who’ve trouble finding care. And several anxious dental patients want to dodge the drill.

But the liquid may be especially helpful for children. Nearly 25 % of 2- to 5-year-olds have cavities, in accordance with the Centers for disease control and Prevention.

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

“S.D.F. gives us a way to decrease the variety of toddlers with cavities going to the O.R.,” said Dr. Arwa Owais, an affiliate professor of pediatric dentistry on 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 trip to the operating room.

Dr. MacLean said, “People feel that parents will reject it due to poor aesthetics.” But “if it means preventing a youngster from having to be sedated or having their tooth drilled and filled, there are many parents they like S.D.F.,” she added.

Alejandra Bujeiro, 32, was delighted that her 3-year-old daughter, Natalia, didn’t need to have two cavities completed the back 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 next time, Ms. Bujeiro said, she’d opt for silver diamine fluoride. “I would put it to use in baby teeth even when it’s in the front,” she said. Are you aware that discoloration? “You can’t notice a lot of.”

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

“S.D.F. cuts down on the incidence of latest caries and growth of current caries by about 80 %,” said Dr. Niederman, who’s updating an evidence writeup on silver diamine fluoride published last year.

Fillings, electrical systems, usually do not cure an oral infection.

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

That’s why some children should have pediatric dentist under anesthesia twice.

Microbe infections also cause acne, but 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 features a Facebook page called SDF Action, where dentists can discuss individual cases.
