Which statement best describes symptoms of caries when the disease is mild?

• A. Mild disease is often asymptomatic
• B. Pain is a common early sign
• C. Abscess formation is typical
• D. Cellulitis is commonly observed

Answer: (A)

In the mild stage, caries has just begun to affect the enamel and has not yet irritated the pulp, so there are typically no symptoms. Pain or sensitivity appears only after the lesion progresses and dentin or the nerve becomes involved, which marks a more advanced stage. Abscess formation and cellulitis indicate infection and tissue destruction beyond early decay, not what you’d expect with mild disease. Early caries may sometimes be seen as a white-spot lesion or subtle enamel demineralization, detectable during exam or with imaging, even though the patient feels no pain. Therefore, mild caries is best described as often being asymptomatic.
