Early birth and periodontal disease have been found to not correlate with each other.

In 2006, an article was published, reporting that women with gingivitis and periodontal disease can lead to preterm birth and low birth weights.  Many people argue about treating pregnant women for periodontal disease, but a recent study published in the December issue of the Journal of the American Dental Association suggests that the correlation between treated and untreated periodontal disease and preterm birth and low birth weights does not change.  It should be noted, however, that periodontal disease is an infection of the gum tissue, and any infection can lead to serious complications with pregnancy and should be treated accordingly.  Pregnancy can also cause a rise in gingivitis due to the hormones released, making the dentist ask for more frequent cleanings.  Please visit the American Dental Association for more information on these topics
