Eight Reasons to Take Good Care of Your Teeth When Pregnant
A pregnant woman has a lot to think about while preparing to welcome a new member of her family. It's important to think about her oral health as well. She is sharing her body with the developing infant, so problems with her health — including her dental health — can affect the baby. The following facts will help you understand the relationship between oral health and pregnancy.
- A baby's primary (baby) teeth begin to form during the sixth week of pregnancy. They begin to form their enamel (the hard outer layer of the teeth) and dentin layer (just under the enamel) at about the third or fourth month. The calcium, phosphorous, and protein that are needed for these structures must all be provided by the mother's diet.
- A good diet for a pregnant mother, in order to provide for both her needs and those of the fetus (the developing baby), includes whole grains, fruits, vegetables — including green leafy vegetables — proteins and dairy products. A doctor may also recommend iron and/or folic acid supplements.
- If the mother's diet does not provide enough calcium for the baby's bones and teeth, it will come from calcium stored in her bones — not from her teeth. The old idea that a mother's teeth lose calcium during pregnancy has been found to be a myth.
- Progesterone, a normal female hormone, is elevated during pregnancy. This hormone stimulates production of prostaglandins, substances that cause inflammation in gum tissues if the bacteria that cause periodontal (gum) disease are present. The resulting swelling, redness, and sensitive gum tissues, called pregnancy gingivitis, are common during the second to eighth months of pregnancy.
- The bacteria involved in periodontal disease can affect whole body conditions such as heart disease and strokes, diabetes, and respiratory diseases. The inflammation resulting from such bacteria can also cause premature delivery (birth before 37 weeks of pregnancy) or low birth weight in the baby.
- Periodontal disease is also related to pre-eclampsia, or high blood pressure, during pregnancy.
- Dental x-rays do not expose the mother to very high radiation, but in any case every precaution is taken to minimize exposure to the fetus. These include a leaded apron that shields the baby from exposure.
- Most drugs commonly used in dentistry, including local anesthetics, can safely be given to pregnant women without affecting the fetus. However, it is important to let your dentist know you are pregnant before embarking on any treatment to make sure anything that is done will be safe for the fetus and its developing teeth.
