text: The "40% of teenagers" is in reference to a 2010 study by Beltran-Aguilar in which 41% of adolescents they examined showed signs of dental fluorosis.  This was as follows:  37.1% mild to very mild dental fluoosis, 3.8% moderate.  Mild dental fluorosis is a barely detectable effect which causes no adverse effect on form, function, or health of teeth.  As peer-reviewed science has shown these teeth to be more decay resistant, many consider mild dental fluorosis to not even be undesirable, much less adverse.
  
  The 3.7% moderate was attributable to improper ingestion of toothpaste, or exposure to abnormally high levels of environmental or well-water fluoride during the teeth developing years of 0-8.
  
  In fear-mongering about faint white streaks on teeth, antifluoridationists hypocritically ignore the lifetimes of pain and devastation of untreated dental infection which can be, and is, prevented by water fluoridation.
