Link between Mouth-rinse and Preterm Birth

A new study reports that the use of non alcohol antibacterial mouth-rinse is linked to a decreased incidence of preterm birth. The study followed pregnant women at 6 to 20 weeks gestation that had periodontal disease and were not receiving additional dental care. Of mothers who used the mouthwash twice a day, 6.1% delivered prematurely, compared with 21.9% of the control group, who did not use the mouthwash.

After adjusting the findings for smoking status and age, the rate of premature birth in those who used the mouthwash was around two-thirds less than those who did not. The study’s authors, who were surprised with the results, noted that hormone surges in pregnancy can cause the gums to swell and that too much inflammation may trigger premature labor. The results of the study emphasize the importance of preventative dental care during pregnancy.
