Study shows quick liquid treatment can halt cavities in young children

A multi-institutional Phase III trial involving 830 children younger than six demonstrated that a 38% silver diamine fluoride (SDF) liquid halted tooth decay in over half of the affected baby teeth when applied at six-month intervals. Conducted in dental clinics, pediatric practices and Head Start programs in Michigan, New York and Iowa, the study showed the quick, non-invasive method requires only a sponge applicator and no drilling, injections, or anesthesia.

Researchers highlighted the potential to spare thousands of children from painful dental procedures and emergency-room visits. The findings supply the robust U.S. data needed for the FDA to consider approving SDF specifically for cavity arrest, moving it beyond its current off-label use. Lead investigators noted that while the treatment permanently darkens the decayed area, many families may prefer avoiding pain and surgery. Broader adoption could also benefit adults and people with limited dental access.
