Which statement about fluoride mouth rinses is true?

• A. Provides moderate-dose (226 mg/L) fluoride topically on a daily basis; Effective and available OTC; Requires active use; Younger children incapable of rinsing and expectorating
• B. Provides 226 mg/L fluoride topically on a daily basis; Not effective
• C. Provides high-dose fluoride topically weekly; Not available OTC
• D. Not a fluoride delivery method

Answer: (A)

Fluoride mouth rinses deliver a moderate amount of fluoride topically with each use, and are intended for regular, typically daily, use to help remineralize enamel between brushing. They are available over the counter, so they’re accessible without a prescription. Because the fluoride works by contacting the tooth surfaces, you need to actively swish the rinse around the mouth and spit it out rather than swallow. This is why they’re generally recommended for individuals who can rinse and spit reliably, with younger children often needing supervision or not using them at all. Taken together, these features explain why a daily, moderate-dose, OTC fluoride rinse that requires active use is true, while other statements that claim no effectiveness, or that the rinse is high-dose weekly or not a fluoride delivery method, aren’t accurate.
