Some experts recommend that if you’re going to avoid X-rays, the best time to do so would be your first trimester. However, it’s generally considered safe to see the dentist at any point. That being said, many women feel uncomfortable laying back during their third trimester, due to the baby’s size.
If you’re planning to get pregnant, it’s best to go ahead and catch up on any dental work that you need to have done, or plan to get it completed by your second trimester. In fact, current research shows that women who have trouble conceiving — and have active gum disease — may conceive more quickly once their periodontal infection is treated.
