Nobody looks forward to having a cavity drilled and filled by the dentist. Now there’s an alternative: an antimicrobial liquid that may be brushed on cavities to prevent cavities – painlessly.
The liquid is termed silver diamine fluoride, or S.D.F. It’s been useful for decades in Japan, but it’s been for sale in the United States, under the brand Advantage Arrest, for nearly 12 months.
The meals and Drug Administration cleared silver diamine fluoride to use as being a tooth desensitizer for adults 21 and older. But studies show it may halt the growth of cavities preventing them, and dentists are increasingly using it off-label for anyone 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 on the University of Michigan.
Silver diamine fluoride is used in countless dental practices. Medicaid patients in Oregon increasingly becoming the procedure, and at least 18 dental schools have begun teaching the next generation of pediatric dentists how to use it.
Dr. Richard Niederman, the chairman from the epidemiology and health promotion department on the The big apple University College of Dentistry, said, “Being able to paint it on in 30 seconds without having noise, no drilling, is way better, faster, cheaper.”
“I would encourage parents to ask for it,” he added. “It’s less trauma for that kid.”
The principle downside is aesthetic: Silver diamine fluoride blackens the brownish decay on a tooth. That will not matter on a back molar or even a baby tooth that may drop out, however some people are probably be deterred from the prospect of the dark i’m all over this an obvious tooth.
Until more insurers buy it, patients also have to cover the cost. Still, it’s pretty cheap. Dr. Michelle Urschel, an anesthesiologist, was very happy to pay $25 to get 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 become drilled cost $151. The liquid “was very inexpensive,” Dr. Urschel said.
The noninvasive treatment might be suitable for the indigent, nursing home residents and others who’ve trouble finding care. And a lot of anxious dental patients desire to dodge the drill.
Though the liquid might be especially a good choice 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 should be treated within a hospital under general anesthesia, though it may pose risks on the developing brain.
“S.D.F. provides for us an opportunity to slow up the variety of toddlers with cavities exploring O.R.,” said Dr. Arwa Owais, an associate 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 because of poor aesthetics.” But “if it means preventing a youngster from having to be sedated or having their tooth drilled and filled, there are numerous parents they like S.D.F.,” she added.
Alejandra Bujeiro, 32, was delighted that her 3-year-old daughter, Natalia, didn’t need two cavities completed 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 when it’s in front,” she said. Alternatives discoloration? “You can’t notice an excessive amount of.”
Silver diamine fluoride has an additional advantage over traditional treatment: It kills the bacteria that create decay. An extra treatment applied six to 1 . 5 years after the first markedly arrests cavities, studies show.
“S.D.F. cuts down on incidence of new caries and growth of current caries by about 80 %,” said Dr. Niederman, who’s updating an evidence report on silver diamine fluoride published during 2009.
Fillings, by comparison, usually do not cure an oral infection.
“There’s nothing that goes on in an operating room that treats the main 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 contains an economic stake in Advantage Arrest.
That’s why some children will need to have pediatric dentist under anesthesia twice.
Bacterial infections also cause acne, however a “dermatologist doesn’t require 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.
