Which of the following can be a consequence of untreated white spot lesions?

Tooth sensitivity
Restored aesthetics
Improved oral hygiene
Enhanced enamel strength

The correct answer is: Tooth sensitivity

Untreated white spot lesions can lead to tooth sensitivity due to the underlying demineralization of enamel. White spot lesions are early signs of tooth decay that appear as opaque white areas on the enamel, indicating that the mineral content of the enamel is compromised. As these lesions progress and enamel continues to demineralize, they can expose the underlying dentin, which is more sensitive and lacks the protective qualities of healthy enamel. This exposure often results in increased sensitivity to temperature changes, sweet foods, and even touch. The other options either contrast with the consequences of untreated lesions or pertain to outcomes that would not arise from them. For instance, restored aesthetics would not be a result but rather a goal of treatment. Improved oral hygiene would typically result from preventive measures being taken rather than being a consequence of neglecting white spot lesions. Likewise, untreated lesions do not enhance enamel strength; rather, they contribute to further weakening of the tooth structure.
