Fluoride is an essential element of toothpaste.
The best remedy for the destruction of teeth — toothpaste with fluoride before bedtime. To such conclusion experts from the University of Dundee (Scotland), reports the Chronicle.info with reference to the Telegraph.
The concentration of fluoride in the toothpaste should be 1350-1500 ppmF, calculated the researchers, and brush teeth not less two minutes.
A particularly important evening cleaning, they point out, because at night, the fluoride from the toothpaste is washed away slowly. To keep fluoride on the teeth, it is also important not to get carried away mouth rinse, add experts.
