Preventive dental cleanings and annual exams during pregnancy are safe, and in fact are recommended. The rise in hormone levels during pregnancy may cause the gums to swell, bleed, and trap food causing irritation. Preventive dental work is essential to avoid oral infections such as gum disease(gingivitis).

Routine dental treatment is generally performed safely during pregnancy. Although non-urgent dental x-rays are usually postponed until after delivery, however, if an x ray is needed for treatment purposes, then it can be taken with the appropriate safety measures. During pregnancy, the second trimester is usually the best time to receive any necessary dental treatment.
Tell your dentist that you are pregnant and about any changes you have noticed in your oral health. Good daily care is important to your oral health.
