Women have special needs when it comes to their oral health. That’s because the physical changes they undergo through life—menstruation, pregnancy and childbirth, breast-feeding and menopause—cause many changes in the body, some harmful to teeth and gums.

Accoding to Mary M. Murry, R.N., C.N.M.:

Consider possible dental health problems during pregnancy(http://www.mayoclinic.com/health/dental-health-during-pregnancy/MY00719):

• Tooth decay. During pregnancy, increased acidity in the mouth increases the risk of tooth decay. Vomiting during pregnancy can aggravate the problem by exposing the teeth to more gastric acid.
• Loose teeth. Increased levels of progesterone and estrogen can affect the ligaments and bones that support the teeth, causing teeth to loosen during pregnancy — even in the absence of gum disease.
• Gum disease. The hormonal changes of pregnancy can lead to gingivitis, an inflammation of the superficial gum tissue. Left untreated, severe gum disease may be associated with preterm birth and low birth weight.

It is important to maintain good oral health during pregnancy.  Make sure to schedule regular dental check ups.
