If you’re nursing, you may be at increased risk for bone loss around your teeth and gums, says a recent study from Tohoku University in Japan. “Women naturally experience a decrease in bone density during breastfeeding and pregnancy as our bodies nourish the baby,” explains Susan Karabin, DDS, president of the American Academy of Periodon-tology. “This study shows that the bone around the roots of teeth is particularly vulnerable.” For a healthy mouth: Brush and floss regularly to keep teeth and gums clean and strong. Get plenty of calcium from your diet. Good sources include dairy (yogurt, cheese, milk), calcium-fortified orange juice and soy milk, sardines and beans. Consider a supplement. Talk to your doctor about the type and dose for you. See your dentist. Have a checkup to rule out a periodontal disease such as gingivitis (ideally, you should do this before your pregnancy). If you have any oral health problems, work with your dentist or periodontist to treat them and help prevent future ones (by getting extra cleanings, for example). Then your smile will be as healthy as your newborn.
