Menopause affects many aspects of health, but one area that often goes unnoticed is oral health. As oestrogen levels decline, the balance of bacteria in the mouth shifts – which can increase the risk of gum disease, inflammation, and tooth decay. Understanding these changes can help you take proactive steps to protect your oral health during menopause.
How oestrogen supports oral health
Oestrogen plays a vital role in regulating the oral microbiome by supporting the growth of beneficial bacteria that help prevent infections. When oestrogen levels drop, harmful bacteria such as Porphyromonas gingivalis and Prevotella intermedia can overgrow, leading to gum disease and increased inflammation.
The impact of menopause on gum health
Beyond microbial balance, oestrogen helps maintain strong, resilient gum tissue. As levels fall, gums can become thinner and more fragile, increasing susceptibility to gingivitis and periodontitis. Many postmenopausal women also experience gum recession, which exposes tooth roots and can lead to heightened sensitivity and a greater risk of decay.
How to support your oral health during menopause
Consider oral probiotics
Beneficial bacteria such as Streptococcus salivarius K12 may help restore microbial balance and reduce harmful bacteria in the mouth. The evidence is still emerging, but this is a promising area of oral health research.
Eat an oral health-friendly diet
Include calcium and vitamin D to support strong teeth and bones. Fermented foods such as yoghurt and kefir may also help nourish a healthy oral microbiome.
Limit sugary and acidic foods
Sugary and acidic foods create conditions that favour harmful bacteria and can accelerate tooth decay and gum damage – risks that are already heightened during menopause.
Maintain good oral hygiene
Brush twice daily with a fluoride toothpaste, floss regularly, and keep up with dental checkups – particularly important during menopause when gum tissue is more vulnerable.
While menopause brings hormonal changes that can affect your oral health, small lifestyle adjustments can make a real difference. By supporting a balanced oral microbiome, you can reduce your risk of gum disease and keep your teeth and gums healthy for years to come.
