If you’re pregnant, your dentist needs to know about the first signs of gum disease symptoms. Pregnant women are at increased risk for periodontal disease because the increased levels of progesterone that come with pregnancy cause an exaggerated response to plaque bacteria. As a result, pregnant women are more likely to develop gingivitis even if they follow a consistent oral health care routine.
Gingivitis is most common during months two to eight of pregnancy. Tell your dentist when you are pregnant — he or she may recommend more frequent dental cleanings during the second trimester or early in the third trimester to help combat the effects of increased progesterone and help you avoid gingivitis.
In addition, eating a balanced diet during pregnancy will help promote dental health and overall health for you and your baby. A baby’s teeth begin to develop between months 3 to 6 of pregnancy, so be sure that you are getting enough calcium, vitamin D, C and A, phosphorous, and protein.
A myth persists that a pregnant woman will lose calcium from her teeth if she isn’t getting enough calcium in her diet during pregnancy. In fact, any calcium loss due to inadequate dietary calcium will occur in the bones, not the teeth. But if you include plenty of calcium-rich foods in your diet during pregnancy, your bones and teeth—and your baby’s bones and teeth—should be strong and healthy.
