Oral health & fertility

~2 extra months to conceive

When you're hoping to grow your family, every healthy choice matters. Research suggests oral health is part of the fertility picture — for both partners — and it's one of the few factors you can actively improve.

Oral health & fertility
What the research shows

The evidence

  1. 1

    In a landmark study of 3,416 pregnancies, women with periodontal disease took on average 7.1 months to conceive versus 5.0 months for women with healthy gums.

  2. 2

    In men attending fertility clinics, greater gum attachment loss correlated with lower sperm motility and count — and over 75% had periodontitis.

  3. 3

    Because gum disease is treatable, addressing it is a simple step a couple can take together.
