Although most dental procedures are safe during pregnancy, it is always best to consult with your dentist or OB-GYN beforehand. Some procedures, such as x-rays, can harm the developing baby. It is generally best to avoid unnecessary dental work during the first trimester. If you need to see a dentist, try to schedule an appointment for later in your pregnancy. Your mouth goes through many changes during pregnancy, which can make you more susceptible to tooth decay and gum disease. Be sure to brush, and floss regularly, and see your dentist for regular cleanings and checkups. With a bit of extra care, you can keep your smile healthy throughout your pregnancy.
