As we get older, many parts of our bodies change; our mouths are no exception. The gums and underlying bone can gradually change shape, which may affect the way dentures fit. Dentures that felt comfortable several years ago may begin to move or cause discomfort. This does not mean you have done anything wrong. Changes in your mouth are a natural part of life. Dental prosthetics should be considered based on your current needs, rather than how things were years ago. If your dentures no longer feel the way they once did, talk with your denturist and learn what your mouth may need now.
