Pregnancy Study at the General and Oral Health Center

Gum disease has been associated with preterm birth1. Two large studies found that up to 40% of pregnant women have some degree of gum disease2. Preliminary data suggest that treatment of gum disease during pregnancy may reduce the risk for preterm birth3. Other investigators have not demonstrated this risk reduction4, emphasizing the need for further research into understanding the link between maternal periodontal (gum) infection and adverse pregnancy outcome.
