Electricity is not likely to turn out to be another lead or asbestos. The reason I ask is my son, now 7 yrs, was born with no enamel on his teeth he has had 6 root canals along with lots of other dental work that started a age 1. At the time I thought this was very odd.
Family history shows no teeth problems.
I've got to say that this has bothered me for quite a while now. All the Dentists said that it was either because I nursed him or that I was very sick with a high fever when pregnant. I was never sick. Nursing is the best thing you can do for your child. I was pregnant in Seattle.
