This study aims to evaluate the fluoride levels in toothpaste products currently sold in the Libyan market. 30 different brands of toothpaste products (9 for children and 21 for adults) were analyzed to evaluate their fluoride concentrations. A spectrophotometric method; was employed to assess the fluoride concentration. Results showed that nine tested children's toothpaste samples contained a fluoride level below 500 ppm, which suits kids. In contrast, 18 adult toothpaste samples had a total fluoride concentration of 500 and 1500 ppm. Three adult toothpaste samples exceeded the recommended fluoride concentration more than 2000 ppm. The analysis revealed that 85.7% of the samples contained fluoride within permissible limits, while 14.3% had fluoride levels higher than the allowable limits. It can be concluded that the fluoride content in children's toothpaste appears to be in line with the recommended optimal amounts. However, there was a widespread disparity in fluoride concentrations for other samples.
