Oral Health and Pregnancy: Gum Disease Affects Fertility
Poor oral health linked to delayed conception and pregnancy complications like preterm birth. The Smile Study found poor oral health affects conception time similarly to obesity. Periodontal disease, caused by bacteria, creates gum inflammation and pockets that increase infection risk.
Key Takeaways
Periodontal Disease and Fertility: Prolonged Conception Time
Research shows women with gum disease may take longer to conceive. The bacteria causing periodontal disease trigger inflammation, leading to receding gums and infected pockets. This inflammation disrupts hormonal balance and reduces fertility potential.
Oral Health in Pregnancy: Reducing Preterm Birth and Miscarriage Risks
Periodontal disease is strongly associated with preterm birth and miscarriage. Chronic inflammation from gum disease increases systemic stress on the body, potentially triggering early labor. Maintaining gum health before conception lowers these pregnancy risks.
Periodontal Screening Before Pregnancy: A Preventive Measure
Dental evaluations should be part of preconception health planning. Treatments like deep cleanings or antibiotics for infected periodontal pockets can resolve inflammation. The Smile Study emphasizes that oral health interventions improve conception timelines as effectively as weight management.
