  "account": "A large clinical trial has confirmed that a simple liquid treatment called silver diamine fluoride (SDF) can stop tooth decay in young children without the need for drilling, injections, or sedation. Published in JAMA Pediatrics, the Phase III trial involved 830 children under the age of 6 from Michigan, New York, and Iowa. The researchers found that a 38% solution of SDF stopped decay in more than half of the affected baby teeth when applied at six-month intervals. Dentists apply the liquid directly to the cavity using a small sponge tip, which requires no drilling, injections, or sedation. The treatment works by combining the effects of silver, which combats decay-causing bacteria, and fluoride, which strengthens tooth enamel and resists further damage. Tooth decay is the most common chronic disease among children, affecting over 40% of American kids. Untreated cavities can lead to severe toothaches, infections, eating and sleeping problems, missed school days, and repeated medical visits. SDF provides an alternative for many challenging patients, such as young children, those with disabilities, or individuals with severe dental anxiety. However, the treatment permanently darkens the decayed portion of the tooth, which may be a cosmetic concern for some families. Despite its decades-long use in other countries, SDF hasn't received FDA approval for cavity treatment in the U.S. due to a lack of large-scale clinical evidence. The Michigan study fills this gap, potentially paving the way for broader use of the safe and effective treatment, including in pediatric medical settings.",
  "summary": "A simple liquid painted onto teeth in seconds can stop cavities without drilling, injections, or anesthesia, according to a major clinical trial involving young children. The inexpensive treatment could spare thousands of children painful dental procedures and surgery while paving the way for broader FDA-approved use.",
