Oral health care during pregnancy recommendations for oral health professionals.

Pregnancy is a unique time in a woman's life and is characterized by complex physiological changes. These changes can adversely affect oral health. Pregnancy is also an opportune time to educate women about preventing dental caries in young children, a common childhood problem. Although multiple studies have shown an association between periodontal infection and adverse pregnancy outcomes, such as premature delivery and low birth weight, recent randomized clinical trials conducted in the United States failed to show that treatment of periodontal disease during pregnancy improved birth outcomes. However, the studies confirmed the safety and effectiveness of providing oral health care during pregnancy. Pregnancy by itself is not a reason to defer routine dental care and necessary treatment for oral health problems. Diagnosis and treatment, including needed dental X-rays, can be undertaken safely during the first trimester of pregnancy. Needed treatment can be provided throughout the remainder of the pregnancy; however, the time period between the 14th and 20th week is considered ideal.
