If you have been wearing dentures for a long time, the ligaments supporting them may weaken over time and cause your dentures to become loose or move about too much. Ill-fitting dentures are uncomfortable and can cause pain in the jawbone, which is why it's important to keep up with regular adjustments.
Some common problems with Ill-fitting dentures include:
Difficulty opening the mouth wide enough for food to pass through without obstruction or pain – this can lead to choking or gagging when eating or drinking.
Difficulty getting a full range of motion while chewing or speaking – this can lead to injury from wearing down teeth or grinding, as well as pain from jaw fatigue (from constantly opening and closing).
Difficulty breathing through the nose – this can lead to congestion, sinusitis, and headaches.
