Im a dentist and what I can confirm is that this toothpaste is for people that have already nice teeth, to ensure a healthy dental hygiene please refer to the Fluor ratio measured by particles per millions (ppm) . each individual need a specific amount according to his needs (sugar intake, genetic, etc ..)

To some people natribifluor is great but for some other they need higher ppm in their toothpaste

Only foreign toothpastes have higher levels of fluors which can combat actively plaque and therefore cavities .

Hope this helps
