What is the typical fluoride concentration for fluoridated toothpaste used for topical application?

• A. 1000 mg/L
• B. 226 mg/L
• C. 500 mg/L
• D. 50 mg/L

Answer: (A)

Fluoride toothpaste for topical use is formulated to deliver fluoride to the tooth surface in a level that promotes remineralization without excessive ingestion. The amount is usually described in parts per million (ppm) of fluoride, and most standard toothpastes contain about 1000 to 1500 ppm F. That translates to roughly 1000 to 1500 mg of fluoride per liter of toothpaste. This range is chosen because it provides an effective remineralization effect and caries reduction when used regularly, while keeping safety in mind for everyday use. Pediatric toothpastes are often lower to reduce ingestion risk. Among the given options, 1000 mg/L matches the common standard for regular-strength fluoridated toothpaste. The other values are below the typical range and would offer less fluoride exposure for topical benefit.
