This Mineral, Typically Added to Drinking Water, Makes Enamel More

Question

This mineral, typically added to drinking water, makes enamel more resistant to dissolving in acid.
A)calcium
B)chlorine
C)chloramine
D)fluoride

Accepted Answer

Fluoride is known to strengthen enamel by making it more resistant to acid erosion. It is commonly added to drinking water as a public health measure to prevent tooth decay. Calcium may also contribute to stronger enamel, but fluoride is the mineral typically associated with this benefit. Chlorine and chloramine are disinfectants commonly used to treat drinking water but do not have the same effect on enamel as fluoride.
