Nobody looks forward to using a cavity drilled and filled by a dentist. Now there’s an alternate: an antimicrobial liquid that can be brushed on cavities to halt dental cairies – painlessly.
The liquid is called silver diamine fluoride, or S.D.F. It’s been used for decades in Japan, but it’s been accessible in the us, underneath the brand Advantage Arrest, for nearly 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 could halt the progression of cavities preventing them, and dentists are increasingly using it off-label for all those purposes.
“The upside, the fantastic one, is you don’t must drill so you don’t need an injection,” said Dr. Margherita Fontana, a professor of cariology in the University of Michigan.
Silver diamine fluoride has already been found in countless dental practices. Medicaid patients in Oregon are experiencing the procedure, and a minimum of 18 dental schools have begun teaching the next generation of pediatric dentists the way you use it.
Dr. Richard Niederman, the chairman of the epidemiology and health promotion department in the The big apple University College of Dentistry, said, “Being in a position to paint it on in A few seconds without any noise, no drilling, is much better, faster, cheaper.”
“I would encourage parents to ask about for it,” he added. “It’s less trauma for your 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 a baby tooth that will fall out, but a majority of people are likely to end up deterred from the prospect of an dark spot on an apparent tooth.
Until more insurers cover it, patients should also cover the price. Still, it’s comparatively cheap. Dr. Michelle Urschel, an anesthesiologist, was thrilled 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 in fact had being drilled cost $151. The liquid “was very economical,” Dr. Urschel said.
The noninvasive treatment could be well suited for the indigent, elderly care residents among others who have trouble finding care. And lots of anxious dental patients need to dodge the drill.
But the liquid could be especially useful for children. Nearly a quarter of 2- to 5-year-olds have cavities, in accordance with the Centers for Disease Control and Prevention.
Some preschoolers with severe cavities have to be treated in the hospital under general anesthesia, though it may pose risks towards the developing brain.
“S.D.F. provides us a way to slow up the number of toddlers with cavities visiting the O.R.,” said Dr. Arwa Owais, an associate professor of pediatric dentistry in 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 visit to the operating room.
Dr. MacLean said, “People think that parents will reject it as a result of poor aesthetics.” But “if it indicates preventing a child from needing to be sedated or having their tooth drilled and filled, there are several parents that like S.D.F.,” she added.
Alejandra Bujeiro, 32, was delighted that her 3-year-old daughter, Natalia, didn’t need 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 very next time, Ms. Bujeiro said, she’d choose silver diamine fluoride. “I would utilize it in baby teeth even though it’s in the front,” she said. Alternatives discoloration? “You can’t view it excessive.”
Silver diamine fluoride has another advantage over traditional treatment: It kills the bacteria that cause decay. A second treatment applied six to 18 months as soon as the first markedly arrests cavities, studies have shown.
“S.D.F. decreases the incidence of recent caries and progression of current caries by about 80 %,” said Dr. Niederman, that’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 that goes on in a operating room that treats the main problem,” said Dr. Peter Milgrom, a professor of pediatric dentistry in the University of Washington who had previously been instrumental in receiving F.D.A. clearance for silver diamine fluoride and contains a financial stake in Advantage Arrest.
That’s why some children will need to have sealants under anesthesia twice.
Microbe infections also cause acne, but a “dermatologist doesn’t have 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 has a Facebook page called SDF Action, where dentists can discuss individual cases.
