Perimenopause can lead to dry mouth as declining estrogen levels affect saliva production. Without enough saliva to naturally cleanse the mouth, bacteria can build up, increasing the risk of gum disease (gingivitis), cavities, and even tooth loss. Some women may also experience a metallic taste or a decreased ability to enjoy food due to changes in taste perception.
In addition, declining estrogen levels can contribute to bone loss — not just in the spine, but also in the jawbone — increasing the risk of loose teeth and eventual tooth loss.
