Early childhood caries (ECC) are preventable and reversible.

• A. True
• B. False
• C. Not described
• D. Depends on case

Answer: (A)

Early childhood caries are preventable through reducing sugar exposure, improving oral hygiene, and using fluoride and sealants appropriately. At the earliest stages, caries lesions are reversible because enamel minerals can be redeposited when fluoride and minerals are available and bacterial activity is reduced. This remineralization stops progression and can even restore a white-spot lesion toward a healthier enamel state. So, the statement is true for the initial, non-cavitated stages of ECC. If a lesion has already cavitated, reversal isn’t possible and treatment typically involves restoration, but prevention and remineralization remain key in managing ECC and preventing progression in most children when addressed early.
