Prematurity and low birth weight affect about 13.4 million infants. Risk factors include placental disorders but also factors related to the mother, such as smoking, alcohol drinking, drug use, malnutrition, or certain diseases. It is imperative to educate women of reproductive age (15\u201349) about the basic factors influencing embryonic development, such as oral health, diet, medicine intake, and harmful habits. Even though most women are aware of the negative impact of harmful habits on the fetus, still too little attention is paid to oral health in pregnant women. Poor oral health may influence the well-being of the future mother, as well as of the child. Therefore, women of reproductive age and those who are pregnant must have adequate knowledge on this subject. The aim of this study was to assess the knowledge of Polish women of reproductive age (15\u201349) regarding oral health during pregnancy, including the impact of dental treatment, oral hygiene, and maternal oral conditions on pregnancy outcomes and the health of the newborn. Materials and Methods: This was a cross-sectional study of 508 women, in the reproductive age, whose age ranged from 18 to 49 years old. The surveys were conducted from April 2020 to November 2020. The questionnaire was originally developed based on the available literature and consisted of seven sections: basic information, general health and habits, pregnancy status and dental care, knowledge of treatment options during pregnancy, oral health status and its association with the risk of preterm birth, prematurity and the child\u2019s oral health, and breastfeeding and oral development. Results: After excluding incomplete questionnaires, a total of 499 questionnaires were included in the analysis. Women participating in the study had a fairly good understanding of the impact of oral health on the fetus and the role of breastfeeding in the development of the stomatognathic system (from 50% to 70% correct answers). However, even though most respondents had completed higher education (344\/68.94%), their knowledge of oral health, preterm birth, and low birth weight was very limited (including the impact of inflammation on the intrauterine development of the child or bacteria and transfer across the placenta). In these sections, the percentage of correct answers ranged from less than 20% to 50%. When analyzing knowledge by age, education, number of births, and place of residence, the highest levels of knowledge were observed among respondents with higher education, particularly those aged 27\u201332. Conclusions: Respondents had a fairly good understanding of the general impact of oral health during pregnancy and recognition of the importance of breastfeeding for infants. However, their knowledge about the impact of bacteria and inflammation in the mother\u2019s oral cavity on prematurity and low birth weight was limited. Therefore, educating women of reproductive age and pregnant women on this topic is essential, as it may help reduce the adverse consequences of prematurity.<\/jats:p>","DOI":"10.3390\/jcm14145153","type":"journal-article","created":{"date-parts":[[2025,7,21]],"date-time":"2025-07-21T09:33:53Z","timestamp":1753090433000},"page":"5153","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The Impact of Oral Health and Dental Care on Pregnancy: A Cross-Sectional Study Among Women of Reproductive Age"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0514-4997","authenticated-orcid":false,"given":"Paulina","family":"Adamska","sequence":"first","affiliation":[{"name":"Division of Oral Surgery, Medical University of Gda\u0144sk, 7 D\u0119binki Street, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2263-6793","authenticated-orcid":false,"given":"Hanna","family":"Sobczak-Zagalska","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Medical University of Gda\u0144sk, 18 Orzeszkowej Street, 80-204 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zuzanna","family":"Gromek","sequence":"additional","affiliation":[{"name":"Scientific Circle of Oral Surgery, Medical University of Gda\u0144sk, 7 D\u0119binki Street, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4003-1170","authenticated-orcid":false,"given":"Barbara","family":"Wojciechowska","sequence":"additional","affiliation":[{"name":"Scientific Circle of Oral Surgery, Medical University of Gda\u0144sk, 7 D\u0119binki Street, 80-211 Gda\u0144sk, Poland"},{"name":"Department of Maxillofacial Surgery, Medical University of Gda\u0144sk, 17 Mariana Smoluchowskiego Street, 80-214 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulina","family":"Doroszkiewicz","sequence":"additional","affiliation":[{"name":"Scientific Circle of Oral Surgery, Medical University of Gda\u0144sk, 7 D\u0119binki Street, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7255-4868","authenticated-orcid":false,"given":"Marek","family":"Chmielewski","sequence":"additional","affiliation":[{"name":"Scientific Circle of Oral Surgery, Medical University of Gda\u0144sk, 7 D\u0119binki Street, 80-211 Gda\u0144sk, Poland"},{"name":"Private Dental Practice, 14 Kolberga Street, 81-881 Sopot, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7673-4460","authenticated-orcid":false,"given":"Dominika","family":"Cicho\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Periodontology and Oral Mucosa Diseases, Medical University of Gda\u0144sk, 18 Orzeszkowej Street, 80-204 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam","family":"Zedler","sequence":"additional","affiliation":[{"name":"Division of Oral Surgery, Medical University of Gda\u0144sk, 7 D\u0119binki Street, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Pilloni","sequence":"additional","affiliation":[{"name":"Section of Periodontics, Department of Oral and Maxillo-Facial Sciences, Sapienza University of Rome, 00-185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1080\/00016350802307620","article-title":"Postpartum oral health parameters in women with preterm birth","volume":"66","author":"Heimonen","year":"2008","journal-title":"Acta Odontol.
