Your gums are constantly changing. When the remaining gum or residual ridge atrophies or “shrinks”, it results in changes to the shape of the face and mouth. As a result of these changes, your denture will no longer fit properly. By refitting or “relining”, your denturist can reshape the denture base to compensate for these changes. Signs that indicate your denture should be examined for relining include: sore, painful gums, loose denture and cracked or broken denture. See your professional denturist to ensure that the comfort, fit, and appearance of your denture will keep you smiling.
