Oral health & pregnancy
Oral health is an important and often overlooked part of a healthy pregnancy.
What the research describes
Systematic reviews and meta-analyses have examined periodontal disease alongside pregnancy outcomes, reporting associations with preterm birth and low birth weight. The proposed pathway involves inflammatory mediators and bacteria reaching the placenta. Hormonal changes during pregnancy also make gum tissue more prone to inflammation, so the risk is not static across those nine months.
Why it matters for prevention
Dental care during pregnancy is safe and recommended. Skipping it is the actual risk. Many patients avoid the dentist while pregnant out of caution, which is precisely backwards.
How we look at it here
We provide gentle preventive care tailored to each stage of pregnancy, adjust positioning and timing for your comfort, and coordinate with your OB when anything warrants it. Expect education, not alarm.
By the numbers
Findings as reported in the studies linked below. Every figure was read from the source itself. Where a result is borderline or contested, we say so.
- RR 1.6 95% CI 1.3–2.0
- Higher risk of preterm birth associated with periodontal disease, from the systematic reviews judged to have the lowest risk of bias. Daalderop 2018, overview of 23 systematic reviews
- RR 1.7 95% CI 1.3–2.1
- Higher risk of low birth weight, from the same set of reviews. Daalderop 2018
