Fluoridated Water and Toothpaste

APES-FTVXQ1

Using toothpaste with fluoride and drinking fluoridated water reduces tooth decay by at least 25%. Ingesting too much fluoride can lead to dental fluorosis in children and skeletal fluorosis in adults.

Since 1997, the FDA requires a poison warning on fluoridated toothpaste: “Keep out of reach of children under 6 years of age. If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately.”

Which statement BEST explains why we allow sodium fluoride to be used in toothpaste?

A

The benefits of significantly reducing cavities outweigh the risks of swallowing too much toothpaste.

B

The expense of dental treatments is insignificant compared to the expense of medical treatment for a fluoride overdose.

C

The general population has a significant risk aversion for fixing cavities by drilling teeth.

D

The FDA does not monitor personal care products like toothpaste.

E

During a risk assessment, it was determined that the probability of an occurance was greater than the potential loss.
