Clinical and experimental evidence consistently demonstrates that early dental caries confined to the enamel (non-cavitated white spot lesions) can be biologically halted or reversed through remineralization therapies before they reach the dentin.
The claim specifically addresses the biological reversal of dental cavities before reaching the dentin (i.e., early enamel or non-cavitated caries). Step 0 check shows the claim is specific and empirical. Numerous retrieved studies (e.g., [0], [2], [3], [6], [9], [11]) investigate non-cavitated lesions, white spots, and remineralization processes, confirming that early demineralization in enamel can be arrested or reversed. There are no papers refuting this well-established dental phenomenon. Thus, the verdict is SUPPORTED.
