Menopause is well-known for causing hot flashes and night sweats for many women. But the list of menopause maladies can also include dental problems. Hormonal changes — mainly a sharp drop in estrogen — can reduce bone density and saliva production and harm your gums. And all of this can affect your teeth. Oral care experts say you can counteract these effects with good oral hygiene, nutrition and hydration. They also suggest doing more frequent dental visits, in-office fluoride treatments, prescription high-fluoride toothpaste and over-the-counter treatments for dry mouth.
