Optimal health during pregnancy is crucial for ensuring the well-being of the mother and the developing fetus. This article is focused on the impact of oral health and the role of personalized oral hygiene management in addressing prevalent dental issues among pregnant women, with particular emphasis on periodontal disease and dental caries. Despite the high prevalence of these dental problems and their association with obstetric complications such as pre-term birth and low birth weight, many pregnant women do not receive adequate dental care. This gap in care is often due to misconceptions about the safety of dental treatments during pregnancy and lack of awareness on the part of healthcare professionals. Appreciations of the impacts of oral health and personalization of oral hygiene strategies such as tailored education and support, have proven effective in improving oral health in this population. Significant reductions in the incidence of caries and periodontal disease may be achieved by adapting care to the specific needs of each patient, thereby enhancing maternal and fetal health outcomes. Integration of personalized oral hygiene management into maternal health programs and enhancement of ongoing education for pregnant women and healthcare professionals are essential steps in the reduction of pregnancy-related risks and improvement of maternal and neonatal well-being.
