A white spot lesion on a tooth is an indication of what?

• A. Advanced decay
• B. Sealant failure
• C. Early caries
• D. Enamel erosion

Answer: (C)

A white spot lesion on a tooth typically indicates early caries. This condition signifies a demineralization of enamel due to the presence of acid-producing bacteria that thrive on sugars. At this stage, the enamel has not yet cavitated, which means that while there has been some loss of minerals, the structural integrity of the tooth has not been compromised to the extent seen in advanced decay. Identifying a white spot is crucial because it represents an opportunity for intervention before a cavity forms. This stage allows for remineralization to occur, and with proper care—such as fluoride treatments and better oral hygiene—further decay can often be halted or even reversed. In contrast, advanced decay usually presents as a more serious issue, with deep cavities and possibly the need for restorative treatment. Sealant failure would imply that a dental sealant applied to a tooth has not held up effectively, but does not inherently indicate early caries. Enamel erosion refers to the loss of enamel due to factors like acid exposure, but it is distinct from the localized demineralization seen in white spot lesions.
