Question: 1 / 180

Fluoride is typically introduced in all of the following ways except by ____________?

Drinking water

Vitamins

Injection

Fluoride is commonly introduced to the body through drinking water, vitamins, and toothpaste, but it is not typically administered via injection. Drinking water often has fluoride added to enhance oral health at the community level. Vitamins can also contain fluoride supplements for those who may not be getting enough from other sources. Toothpaste is a well-known method where fluoride is directly applied to the teeth, aiding in the prevention of dental caries.

Injecting fluoride is not a standard practice for introducing fluoride into the body. The oral and topical applications of fluoride (like in water, vitamins, and toothpaste) have been shown to be effective in promoting dental health, making these methods preferable and safer for systemic absorption and local application.
