Adding fluoride ions to toothpaste and drinking water converts the mineral in tooth enamel, hydroxyapatite, to fluoroapatite. This conversion is beneficial in preventing tooth decay because fluoroapatite ________
A)solubility is less pH dependent.
B)makes strong hydrogen bonds.
C)prevents halitosis.
D)repels decay-producing bacteria.
E)kills decay-producing bacteria.
