We use an 1000ppm fluoride tooth paste from birth to the age of 8 years according to the guidlines of the American Academy of Pediatric Dentistry. On children under tha age of 3 years and a hal,f we use a very small amount like a smear layer, because all kids of that age swallow the toothpaste.Later on when they learn how to rince and spit, we increase the 1000ppm fluoride toothpaste to a pea size amount.
