Cost Liquid Can Stop Kids’ Cavities Without Drilling

Key Points:

• A large U.S. clinical trial found that silver diamine fluoride (SDF), a low-cost liquid applied directly to decayed teeth, can effectively halt cavity progression in young children without the need for drilling, injections, or anesthesia.
• The Phase III trial involving 830 children under six showed that applying 38% SDF every six months arrested decay in over half of affected baby teeth, offering a safe, noninvasive alternative to traditional cavity treatments.
• SDF treatment is particularly beneficial for populations who struggle with conventional dental care, such as toddlers, older adults, individuals with disabilities, and those with dental anxiety or limited access to dentists.
• While the treatment causes the decayed area of the tooth to turn permanently dark, its ease of application and effectiveness could lead to FDA approval, wider insurance coverage, and increased adoption by healthcare providers.
• Researchers highlight that repeated SDF applications may preserve baby teeth until natural loss and provide long-term cavity management or temporary protection for adults awaiting restorative dental work.
