As people age, they may be more likely to take multiple medications, which can have an impact on oral health. Some medications can cause dry mouth, which can lead to tooth decay and gum disease. Other medications can cause changes in taste and appetite, which can lead to poor nutrition and oral health problems. Additionally, some medications can cause changes in the color of the teeth or the tissues in the mouth. It's important for older adults to talk to their dentist and physician about any medications they are taking and how they may impact oral health.
