Oral Hygiene, Preeclampsia, Preterm Birth

I’d previously read that gingivitis is associated with higher rates of preeclampsia, but that it was not known if it was a “cause and effect” or just an association. If gingivitis causes preeclampsia, then better oral hygiene might prevent some cases of preeclampsia; but if it’s just an association — that women who are predisposed to either gingivitis or preeclampsia, or just are in poorer health or have an underlying health condition — then combatting gingivitis would do nothing.

In that vein, I was intrigued when I read this article, which said that bacteria has been found in the amniotic fluid of women who have given birth prematurely. One possible pathway given was that a kind of bacteria normally found in the mouth (and harmless there) may make its way into the bloodstream, and from there through the placenta into the baby’s amniotic fluid. This might weaken the amniotic sac, or perhaps cause some sort of uterine infection or fetal infection, or something that would account for the preterm birth. This is a new discovery, because this bacteria does not respond to traditional culturing, but instead requires examining DNA.

I wonder if preeclampsia might also be a manifestation of some sort of infection, perhaps transmitted through the weakened areas of the mouth when gingivitis occurs — the puffy and bleeding gums just seem like wide-open places for bacteria to cross into the blood-stream.

As an aside, I had two heart surgeries as a young child, and am supposed to take antibiotics for life whenever I have dental work done. It’s to prevent this sort of thing from happening — nasty oral bacteria (that may do nothing worse than cause bad breath, plaque or cavities when kept in the mouth) upon entering the bloodstream move to the weakest point, which for heart patients would typically be the heart. Southern humorist Lewis Grizzard eventually lost his life because of this — after four heart surgeries. In a pregnant woman, the baby may be “the weakest point” which is attacked, or at least may be the area with the least defenses. Antibiotics are given with the hope and assumption that if the dental patient’s mouth is pricked or otherwise open and/or bleeding, and oral bacteria enter the bloodstream, that the prescription antibiotics will prevent these bacteria from setting up a heart infection.

When I was pregnant the first time, I didn’t know about the gingivitis-preeclampsia risk, much less this newly released bacteria-preterm birth link. But I did know about the possibility that always exists (no matter how small) for oral bacteria to enter the bloodstream through an open sore in the mouth. I assume the risk is much greater when, say, the pick that cleans your teeth and may have untold numbers of bacteria on it jabs into the gum and more or less “injects” the bacteria below the surface. However, when my gums bled during pregnancy — which is not uncommon — I was concerned and wondered what to do about it. Sometime in the past, I had read that gingivitis might be caused by a lack of vitamin C, or at least, that taking vitamin C would stop it. You’re not supposed to take large amounts of vitamin C while pregnant because the baby might develop scurvy (although I think this is mostly talking about large doses around the time of birth, causing the baby to develop scurvy after birth when he’s withdrawn from the maternal vitamin C; and I’ve read one doctor who prescribes large doses of vitamin C, and his protocol for dealing with this is to give the baby vitamin C as well, and then gradually wean him off of it), so do your own research before doing anything! So I took a couple of grams of vitamin C for a few days, in addition to whatever was in my prenatal vitamin, whenever my gums started bleeding, and usually within a day it would stop. I only had to do this a few times during pregnancy.
