[Tooth and pregnancy, a public health issue].

Pregnancy is a particularly risky moment for periodontal and oral healthcare. The main diseases encountered are the development or worsening of carious lesions and gestational periodontal diseases such as gingivitis, epulis or gestational periodontitis. There is a lack of knowledge from health professionals and their patients, firstly on the link between poor oral hygiene and the impact on pregnancy, and secondly on the feasibility of oral care during pregnancy. There is a link between periodontal diseases and the increase of premature delivery risk, child with low birth weight and pre-eclampsia. Periodontal care during pregnancy would lower this risk. However, no link has been highlighted to date between oral care provided during pregnancy and the reduction of premature delivery or even of pre-eclampsia. Loco-regional anaesthesia and taking x-ray images-even dental panoramic radiography-are not contraindicated for pregnant women. All periodontal and oral care can be performed during pregnancy, at all gestational ages.
