There are a couple of dental conditions that can arise during pregnancy.
Enamel Erosion
Morning sickness is a major symptom of pregnancy for many women. Frequent vomiting or reflux introduces stomach acids into the mouth that can erode your teeth. Be sure to rinse your mouth out with water or with a fluoride mouthwash after an acidic episode. It is best to delay brushing your teeth for one hour and to use a toothbrush with extra soft bristles.
Gum Disease
To avoid bleeding gums or other signs of gum disease, teeth and gums need special attention during pregnancy. Regular tooth brushing twice daily with a fluoride toothpaste, flossing once daily and eating a balanced diet will help reduce dental problems that accompany pregnancy.
There is some evidence that women with periodontal disease while pregnant are more at risk of having low birth weight or premature babies, so it is important to take care of your teeth and gums during your pregnancy.
Visiting the Dentist While Pregnant
The second trimester is considered the safest time for both mother and child, for any dental work. During the first and third trimesters of your pregnancy, you should visit the dentist for any urgent dental procedures and always inform the dentist of your pregnancy. If possible, dental X-rays should be avoided throughout the pregnancy.
