Older adults are at an especially high risk for mouth and tooth infections and the complications that can come with these problems. Losing teeth, which is mainly caused by infection, not only leads to changes in our appearance but may also make it harder to chew certain foods. That can make it harder to receive the nourishment we need to function. Complete loss of all teeth (also known as edentulous) is less common now in developed countries like the U.S., but it still becomes more common as we age regardless of where we may live.
