A new study
indicates that there is a connection between fluoride intake and
fluorosis of the permanent incisors. Fluorosis is characterized by
white streaks or splotches on the teeth. Kids in the study, who are
currently 10 to 13 years of age, were followed since birth. The Iowa
Fluoride Study recorded food and beverage intakes multiple times
throughout those years.
The well water and
purchased beverages were analyzed for fluoride concentrations. When the
kids were between 7.7 and 12 years of age, they had dental examinations,
where researchers looked for evidence of fluorosis.
compared amounts of fluoride consumed and children with and without
fluorosis in their permanent incisors. They found that 35% of the
children had some evidence of dental fluorosis, most of which was mild.
records collected at 16 months of age showed that children with
fluorosis had consumed slightly more 100% juice than had children
without fluorosis. More importantly, children with fluorosis consumed
more fluoride from their beverages than did children without fluorosis.
At 6, 9, 12, 16, 24, and 36 months, children with fluorosis had higher
fluoride intakes from all beverages than did children without fluorosis.
At multiple ages, children with fluorosis had higher fluoride intakes
from infant formulas and 100% juice than did children without fluorosis.
Our results suggest that fluoride intake from beverages during infancy
and early childhood can increase the risk of the child's developing

from the University of Iowa found that sugared beverages are playing a
larger role in the diet of the American population. They compared the
erosion caused by various sugared and un-sugared beverages using
extracted teeth. After painting the teeth with nail polish, leaving a
small “window” exposed, they soaked them in beverages for 25 hours.
Then they sectioned the teeth into slices and viewed them through a
microscope to measure erosion.
the most enamel erosion, followed by Red Bull® and Coke®, with Diet
Coke® and apple juice exhibiting the least erosion. It was concluded
that exposure of teeth to sugared beverages caused significant erosion
of both the enamel and root surfaces, but it was not consistent between
beverages, with some specific beverages causing more erosion than
