An 18-month-old has horizontal bright white lines along the upper gum line. What is the most important question to ask the parents?

• A. If the child is still drinking milk from a bottle
• B. If the child or the parents are brushing the teeth
• C. If they are brushing the child's teeth twice daily
• D. If they have taken the child to a dentist

Answer: (A)

Prolonged exposure of a child’s teeth to sugars, especially at night, is the major driver of nursing bottle/early childhood caries. The horizontal bright white lines along the upper gum line suggest enamel was repeatedly exposed to milk sugars in a sleeping child, a common pattern when a bottle is used at bedtime. The most important question to ask is whether the child is still drinking milk from a bottle because this directly identifies the modifiable behavior causing the issue and guides immediate counseling. If the child is still bottle-fed at bedtime, the key step is to stop that practice and switch to water in the bottle, gradually wean from the bottle, and encourage brushing after feeds to reduce sugar exposure. This question also opens the door to advising an early dental visit and establishing a routine of oral hygiene. While questions about brushing habits or dental visits are important for overall care, they do not as directly pinpoint the specific risk factor driving the observed enamel changes as asking about ongoing bottle use does.
