During menopause, levels of the hormones oestrogen and progesterone decrease. These hormones also play a role in oral health. A reduction in oestrogen levels can lower saliva production and increase gum sensitivity.
Saliva protects your teeth from bacteria. With reduced saliva, the risk of cavities and dry mouth increases. Additionally, oestrogen has anti-inflammatory properties. When its levels drop, gums become more prone to inflammation, such as gingivitis or periodontitis.
The decline in oestrogen can also contribute to a loss of bone density, including in the jawbone. For some women, this may result in looser teeth. Changes in the bacterial balance in the mouth can further heighten the risk of cavities and infections such as oral thrush.
