During pregnancy, your body’s hormone levels rise considerably. Gingivitis, especially common during the second to eighth months of pregnancy, may cause red, puffy or tender gums that tend to bleed when you brush. This sensitivity is an exaggerated response to plaque and is caused by an increased level of progesterone in your system. Your dentist may recommend more frequent cleanings during your second trimester or early third trimester to help you avoid problems.
Occasionally overgrowths of gum tissue, called “pregnancy tumors,” appear on the gums during the second trimester. These localized growths or swellings are usually found between the teeth and are believed to be related to excess plaque. They bleed easily and are characterized by a red, raw-looking mulberry-like surface. They are often surgically removed after the baby is born. If you experience pregnancy tumors, see your dentist.
To help prevent tooth decay and periodontal disease, brush your teeth thoroughly twice a day with a fluoride toothpaste to remove plaque. Be sure to clean between your teeth daily with floss or interdental cleaners. Ask your dentist or hygienist to show you how to brush and floss correctly
It’s especially important, then, to maintain good oral health during pregnancy. Studies indicate that pregnant women who have severe periodontal (gum) disease may be at increased risk for pre-term delivery, which in turn increases the risk of having a low-birthweight baby. If you notice any changes in your mouth during pregnancy, see your dentist.
