Pregnancy is a unique physiological state in a woman's life during which her body undergoes numerous changes caused by increased levels of gestational hormones and fetal growth. Some of these changes manifest in the oral cavity, so knowing and understanding them is key to oral, and therefore the overall health, of the expecting mother and child. The dentist's role is to timely inform women about oral changes expected during pregnancy such as gingivitis, periodontitis, epulis, increased tooth mobility and risk of caries, dental erosion, etc. Many of these changes can be prevented or successfully controlled on time by educating pregnant patients about the importance of maintaining good oral hygiene, proper nutrition and regular dental checkups. Most dental procedures can be carried out safely throughout the pregnancy. Thereby, emergencies should be treated immediately regardless of the pregnancy stage, whereas elective procedures are recommended to be postponed until the second trimester when it's safer for both the expecting mother and child. Although pregnant patients are not medically compromised, they require management modifications, not only in treatment but as well in diagnostic procedures and drug therapy used in dental practice.
