Tiny brown spots on teeth often represent early, non-cavitated dental caries (incipient lesions) that can be successfully arrested and remineralized using conservative treatments like resin infiltration, sealants, or specialized peptides.
The retrieved literature contains multiple studies confirming that early carious lesions, including those presenting with microcavitation or discoloration (white and brown spots), can be effectively managed and arrested using non-invasive or minimally invasive interventions such as resin infiltration, sealants, and remineralizing agents.
