Periodontal disease is a type of bacterial infectious disease that causes bone destruction and supportive fibers of periodontal
tissues. It seems the prevalence of this disease is more common in adults and would increase during pregnancy. Researchers believe
hormonal changes are the main factors of developing this disease. Inflammation or infection of the gums increases the risk of low
birth weight and preterm birth. If the problem is left untreated, mothers who would experience severe oral infections and gingival
bleeding during the pregnancy would be at a greater risk for preterm birth.
