The best remedy for the destruction of teeth – toothpaste with fluoride before bedtime. To such conclusion experts from the University of Dundee (Scotland), writes .
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. All these measures will help to reduce the risk of tooth decay by 25%.
Earlier, a group of engineers, biologists and dentists from Penselvansky University have developed a microscopic robotic “crew” that can easily deal with stained teeth. Experts have proposed to use nanoparticles with iron oxide for the destruction of biofilms.
