Basic conversion information: Sodium fluoride has a molecular weight of 42 MW Na (23) + F (19) = 42 NaF in toothpaste is 0.243% weight/volume of NaF (read the toothpaste tube) Convert % NaF to mg/g of NaF compound multiply by 10 = 0.243 x 10 = 2.4
In the UK, the fluoride content is often higher; a 1,450 ppm fluoride is not uncommon. According to the Institute of Medicine (IOM) guidelines in 1997, fluoride intakes of 0.01 mg/day for infants through 6 months, 0.05 mg/kg/day (meaning milligram per kilogram of body weight per day) beyond 6 months of age, and 3 mg/day and 4 mg/day for adult
For comparison, chloride concentration in seawater is about 19 g/L. Use of fluoride supplements is contraindicated in areas where fluoride water content is at least 0.7 ppm. If fluoride concentration in drinking water exceeds 0.6 ppm, do not take additional oral sodium fluoride for dental caries prophylaxis. An 8 fluid ounce glass of fluoridated drinking water (1 ppm or 1 mg/L) provides about 0.2 mg of fluoride.
However, they may require a prescription. In the UK, the fluoride content is often higher; a 1,450 ppm fluoride is not uncommon. According to the Institute of Medicine (IOM) guidelines in 1997, fluoride intakes of 0.01 mg/day for infants through 6 months, 0.05 mg/kg/day (meaning milligram per kilogram of body weight per day) beyond 6 months of age, and 3 mg/day and 4 mg/day for adult So a 70 kg adult would have to swallow 3.5 grams of pure sodium fluoride to be in serious jeopardy. So how much toothpaste do you have to swallow? 1450 ppm is 0.145% so 100 grams of toothpaste has 0.145 grams of NaF. We need to consume 3.5 grams for a lethal dose so 3.5/.145 x 100= 2413 gm or 2.4 kilograms or 5.3 pounds!

The certainty of the evidence was judged to be low with the following exceptions: there was high- and moderate-certainty evidence that 1000 to 1250 ppm or 1450 to 1500 ppm fluoride toothpaste reduces caries increments when compared with non-fluoride toothpaste (SMD -0.28, 95% CI -0.32 to -0.25, 55 studies; and SMD -0.36, 95% CI -0.43 to -0.29, four studies); there was moderate-certainty Basic conversion information: Sodium fluoride has a molecular weight of 42 MW Na (23) + F (19) = 42 NaF in toothpaste is 0.243% weight/volume of NaF (read the toothpaste tube) Convert % NaF to mg/g of NaF compound multiply by 10 = 0.243 x 10 = 2.4 Fluoride is naturally present at low concentration in most fresh and saltwater sources, as well as in rainwater, particularly in urban areas. Seawater fluoride levels are usually in the range of 0.86 to 1.4 mg/L, and average 1.1 mg/L (milligrams per litre). For comparison, chloride concentration in seawater is about 19 g/L.

Das entspricht in etwa der Menge von drei Tuben fluoridierter Zahnpasta oder 1,1 Kilogramm fluoridiertem Speisesalz. Concerning the plaque clearance of fluoride representing consequently the F-bioavailability over the day and night time rather controversial results have been reported: An experimental ex-vivo study demonstrated a rapid and very substantial uptake of fluoride by plaque after exposure to 1000 ppm NaF immersion , whereas from an in-vivo study it was concluded that elevated salivary fluoride concentrations were not reflected in dental plaque, measured 6 h after brushing (1400 ppm fluoride) and
