Simple liquid could stop cavities from progressing: study

Key Points:

• Silver diamine fluoride (SDF), a low-cost liquid treatment used internationally, has shown promise in managing cavities without drilling, injections, or anesthesia, potentially offering a less invasive alternative to traditional dental procedures.
• A University of Michigan trial involving over 800 children under six demonstrated that applying a 38% SDF solution every six months halted decay in more than half of treated baby teeth.
• SDF works by killing decay-causing bacteria and strengthening existing tooth minerals, though it permanently stains decayed areas, which is less concerning in children since baby teeth eventually fall out.
• The treatment could benefit adults as a temporary cavity management option and help individuals with disabilities or dental anxiety who struggle with conventional dental care.
• The new clinical evidence may support FDA approval of SDF for cavity treatment in the US, potentially increasing its use, insurance coverage, and product consistency.
