Preservation-to-Precision in Severe-ECC: When “Buying Time” Must Not Become “Selling Time

.Severe early childhood caries (S ECC) in 3–4 year olds is a preventable disease with consequences that extend beyond teeth to sleep, nutrition, development, family stability, and long term health. In a high income country such as the United States, the central clinical and ethical challenge is not whether minimally invasive dentistry (MID)—including silver diamine fluoride (SDF)—can be used, but whether it is used with appropriate precision and within a system capable of delivering timely definitive care. This editorial argues for a Preservation to Precision movement that transcends “MID” as a narrow technical identity and instead prioritizes child well being as the endpoint: freedom from pain and infection, durable function, and acceptable psychosocial outcomes. Published evidence supports SDF/MID as an evi-dence based tool for lesion arrest and as an interim strategy that can alter care pathways and, in some con-texts, delay escalation to sedation/general anesthesia by weeks to months; however, real world data also show that many SDF treated primary teeth receive subsequent treatment within two years, underscoring that “buying time” is not synonymous with securing long term outcomes to exfoliation. The editorial cautions against redefining temporization as a universal protocol and calls for rights aligned, risk based precision: tooth and child specific planning, realistic appraisal of follow up feasibility, and system reforms that ensure timely access to definitive restorative care when indicated.
