chemical frazzle
Seven years ago, when we moved to Oregon and started seeing a succession of dentists (two in Eugene, two in Portland), we soon realized that every initial dental visit was going to be the same: a look inside our mouths, followed by the dentist proclaiming, “Oho! You must not have grown up in Oregon!”
Many American municipalities fluoridate their water. Caleb and I grew up (on opposite coasts) drinking the stuff, which means that our teeth give off that telltale sparkle, at least to discerning dentists. But fluoridated tap water doesn’t exist here in Portland. And we can’t decide if this is a good thing or not.
If you drink a certain, minimal amount of fluoride, it actually helps build strong teeth from the inside out, as it were. This is useful for children, who are obviously growing teeth. (It’s also moderately useful for slacker adults who can’t be bothered to brush and floss regularly.) But if you drink (or eat) too much fluoride as a child, you wind up with something called fluorosis, in which the enamel of your teeth is mottled and streaky-looking. And some public-health authorities think that fluoridated tap water isn’t useful at all.
Because they’re so little, babies can get too much fluoride from public water supplies, which is why friends in Seattle have tried to find water filters that will remove the stuff, at least temporarily. Meanwhile, pediatricians here in Portland routinely prescribe fluoride drops for babies, because those kiddos aren’t getting any fluoride at all. (Fluoridated toothpaste isn’t recommended for tiny tots, because of the likelihood that they’ll just eat it, and eat too much of it.)
But if you think fluoride drops are just fluoride, think again. The drops we got at our local Walgreens include the colorants D&C red #33 and FD&C yellow #6, the preservatives methylparaben and propylparaben, and the mysterious “peach flavor.”
Does the presumed benefit of taking fluoride outweigh the unknown negative possibilities of downing chemical colorants, flavor agents, and parabens? Nobody seems to know.
I asked our local hippie grocery store if they sold pure fluoride for infants. Nope, but they suggested a local compounding pharmacy to try. The pharmacy, in turn, said that they couldn’t sell fluoride without preservatives because it would go bad within two weeks. (They also said that the company that made the creepy peach-flavored sodium fluoride drops, Hi-Tech Pharmacal, was an OK company to support because it was a local company. Well, me and Michael Pollan are all in favor of buying local food, but local chemicals? Not so much. Besides, the label on the box of peach drops says that Hi-Tech is based in Amityville, New York. So there.)
Some moms here in town just don’t worry about the fluoride thing at all, skipping it entirely until it’s time for their kids to use fluoridated toothpaste. Some are giving their kids the scary drops. Others have been buying fluoridated bottled water (Babies R Us sells it) and giving it to their offspring.
Frustrated, I decided to consult a pediatric dentist. Turns out the guy offers an entirely different line of sodium fluoride for kids; his version still has methylparaben as a preservative, but none of the other unappetizing additives.
As for bottled fluoridated water, he noted that beverage companies aren’t required to list fluoride parts per million on their products. Instead, you have to contact them directly (or check their websites) to find out whether their water contains the optimum level of 1 part fluoride per million. That water from Babies R Us might have too much fluoride, or too little, but you can’t tell just by reading the label.
So now Delphine drinks a little water, lightly fluoridated with the pediatric dentist’s drops, every day. I am still queasy about it, but I am also tired of trying to weigh so many unknowns. After all, Delphine still nurses at least four times a day, which means she’s presumably imbibing flame retardants along with everything else in my body.
Which chemical load is worse for my daughter’s future fertility: the parabens in the fluoride, the PDBEs in the breastmilk, or the hundreds of unknown chemicals drifting around our house and neighborhood?
Oh, and we haven’t even gotten to the lead that’s presumably in our pre-1970s house, or the radon wafting up from our basement, or . . . I know, I know, you’ve heard it all before. The Worrywart Watchlist, signing off for now.
