PCOS & Oral Microbiome
Polycystic ovary syndrome (PCOS) and periodontitis share insulin resistance and chronic low-grade inflammation. Women with PCOS have significantly higher periodontitis prevalence (~50% vs ~30% in matched controls), and successful periodontal treatment improves insulin sensitivity markers in PCOS patients.
The Connection
Chronic oral inflammation amplifies the insulin resistance already driving PCOS, while hyperandrogenism affects gum tissue response to plaque. Distinct oral microbiome signatures (more anaerobic, less diverse) have been documented in PCOS cohorts.
Why Coordination Matters
Endocrinologists and reproductive specialists managing PCOS should add a periodontal screening to the standard metabolic workup. Dentists treating women of reproductive age with severe periodontitis should ask about cycle regularity and acne, both PCOS clues.
What to Watch For
- Bleeding gums alongside irregular cycles
- Recurrent oral thrush
- Excess facial hair and acne with gum problems
Frequently Asked Questions
Does PCOS affect my gums?
Yes — women with PCOS have significantly higher rates of periodontitis (~50% vs ~30%) due to shared insulin resistance and chronic inflammation.
Can treating gum disease help PCOS symptoms?
Periodontal therapy has been shown to improve insulin sensitivity markers, which can secondarily improve PCOS metabolic features.
