Children are often tempted to eat toothpaste. It tastes sweet and usually looks pretty cool too.
Parents supervise their young children’ tooth-brushing habits for a good reason. While fluoride’s ability to help prevent dental caries is well known, it’s also a neurotoxin at high doses. Even at only slightly higher than recommended doses, fluoride can cause unsightly staining of developing teeth.
The practice of fluoridation of domestic water supplies has always attracted controversy. Opponents object to the blanket medication of the population, saying that it’s impossible to control dosage, and that children drink more water than adults by body weight.
Now a wide -ranging meta-analysis of studies shows that there may be a legitimate cause for concern.
Harvard’s School of Public Health found that children in high fluoride areas had significantly lower IQs. The meta-analysis included studies that had previously only been published in China. Researchers concluded that further research was needed to confirm their findings, which they speculated could be attributed to fluoride’s effect on children’s neurodevelopment
Even more reason to make sure your children stick to using a pea-sized blob when they brush.
