Adverse Pregnancy Outcomes and Low Birth Weight

Many women suffer from pregnancy gingivitis. It usually appears during the second trimester and is connected to hormonal changes in the body. The symptoms of pregnancy gingivitis are the same as bio-film induced gingivitis, but the gingival reaction is excessive in relation to the amount of dental plaque.

There is some evidence that suggests an association between periodontitis and adverse pregnancy outcomes, though the data is weak.

Research carried out during pregnancy has not been able to prove whether periodontal treatment will result in less adverse pregnancy outcomes. However, there might be a positive effect of periodontal treatment in women of high risk of low birth weight or preterm birth.

It is safe to carry out the periodontal treatment during pregnancy, preferably during the second trimester, a good time to emphasise the importance of good oral hygiene.

Pregnancy is also a perfect time to start new and better habits. European Federation of Periodontology (2018) has published guidelines for oral-health professionals but also recommendations for pregnant women.

Periodontal treatment and good oral hygiene are a benefit for all patients since it reduces the preventable burden of the systemic inflammation associated with periodontal disease.
