A Cavity-Fighting Liquid Lets Kids Stay away from Dentists’ Drills

Nobody looks forward to developing a cavity drilled and filled by way of a dentist. Now there’s an alternative: an antimicrobial liquid that may be brushed on cavities to halt dental cairies – painlessly.


The liquid is termed silver diamine fluoride, or S.D.F. It’s been used for decades in Japan, but it’s been for sale in the United States, underneath the name Advantage Arrest, for just about 12 months.

The foodstuff and Drug Administration cleared silver diamine fluoride for usage as being a tooth desensitizer for adults 21 and older. But research has shown it may halt the growth of cavities preventing them, and dentists are increasingly utilizing it off-label for anyone purposes.

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

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

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

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

The main negative thing is aesthetic: Silver diamine fluoride blackens the brownish decay over a tooth. That will not matter over a back molar or even a baby tooth that may fall out, however, many patients are probably be deterred through the prospect of the dark right an evident tooth.

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

A cavity which in fact 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 residents yet others who may have trouble finding care. And several anxious dental patients need to dodge the drill.

However the liquid could possibly be especially helpful for children. Nearly one fourth of 2- to 5-year-olds have cavities, according to the Centers for Disease Control and Prevention.

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

“S.D.F. provides a chance to limit the number of toddlers with cavities exploring O.R.,” said Dr. Arwa Owais, a part 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 wished to delay a trip to the operating room.

Dr. MacLean said, “People think that parents will reject it due to poor aesthetics.” But “if it means preventing a young child from needing to be sedated or having their tooth drilled and filled, there are lots of parents that 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 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 next occasion, Ms. Bujeiro said, she’d go for silver diamine fluoride. “I would put it to use in baby teeth even though it’s right in front,” she said. Are you aware that discoloration? “You can’t see it too much.”

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

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

Fillings, by comparison, do not cure an oral infection.

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

That’s why some children must have dental emergency under anesthesia twice.

Microbe infections also cause acne, but a “dermatologist doesn’t have 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.
