Overview
- A University of Michigan‑led Phase III trial of 830 children under six found that 38% silver diamine fluoride stopped decay in more than half of treated baby teeth when applied every six months and the results were published in JAMA Pediatrics in July 2026.
- Clinicians paint the SDF solution onto cavities with a sponge‑tipped applicator in seconds, allowing decay to be arrested without drilling, injections or sedation.
- The study tested Advantage Arrest 38% SDF supplied by Elevate Oral Care and received more than $12 million in funding from the NIH’s National Institute of Dental and Craniofacial Research.
- The primary practical drawback is that the silver permanently darkens the decayed portion of treated teeth, a visible tradeoff that will influence parent and patient acceptance.
- Investigators say the trial provides the clinical evidence a manufacturer can use to seek FDA approval, a step that could change insurance coverage, product standards, clinician uptake and access to care for children and other groups who struggle with standard dental procedures.
