DANB's Topical Fluoride Sample Test

1 of 5

Which of the following is NOT true of fluoride?





Correct Answer:
adequate fluoride is only important once the teeth have erupted.


fluoride is a mineral that is crucial for dental health. it helps to prevent tooth decay by making the tooth enamel more resistant to acid attacks from plaque bacteria and sugars in the mouth. fluoride also aids in the remineralization process, where minerals are redeposited in enamel after they have been removed by acids.

the statement "adequate fluoride is only important once the teeth have erupted" is incorrect and therefore the correct answer to the question. fluoride's benefits begin well before teeth emerge. it is essential during the development of teeth, even before they are visible in the mouth. as teeth form, they are surrounded by a fluid-filled sac which contains fluoride if it is present in the body. this fluoride helps in the formation of strong enamel, setting the foundation for healthy teeth once they erupt.

moreover, fluoride intake during pregnancy is also beneficial as it contributes to the development of the baby's teeth. the mineral can cross the placenta, allowing the developing baby to begin forming strong tooth structures in utero. therefore, adequate fluoride intake is crucial not only after the teeth have erupted but also before and during their formation.

in terms of fluoride excretion, the body eliminates excess fluoride mainly through the kidneys. small amounts may also be excreted through the skin and feces. this helps prevent fluoride toxicity, though excessive intake can lead to conditions such as dental fluorosis during tooth development or skeletal fluorosis in severe cases.

lastly, while fluoride is an essential mineral for dental health, it is important to manage its intake appropriately. excessive fluoride, particularly in areas with naturally high fluoride levels in water, can lead to poisoning and other serious health issues. maintaining a balance is key to utilizing fluoride's benefits without risking its potential harms.
