Over time, dentures will need to be rebased, relined, or remade as a result of normal use and wear. To reline or rebase dentures, the dentist will use the on hand denture teeth but will refit the denture base or completely make a new base for a more secure fit. However, it is likely that denture will need to be replaced if they have become wobbly and they show indications of considerable wear. Dentures that become loose do so as the mouth naturally transforms with age. In time, it is natural to see gum and bone ridges shrink or recede, which can cause the jaws to gradually align differently. Reduction in ridges may cause dentures to fit less securely. Regular check-ups will help determine the need to alter or adjust a denture. These check-ups can help maintain aesthetics by making sure the proper relationship between the jaws is preserved. Keeping jaws in a proper functional association will prevent a premature aging appearance by sustaining the features and shape of the face.

Your dentist will give you advice on how often to visit. Frequent dental check-ups are necessary. The dentist will examine your mouth to evaluate whether your dentures still fit properly or if there is something that needs a quick adjustment in order to avoid major relining later. As a side benefit, your dentist can also look for signs of oral diseases including early detection of possible cancers. Problems with dentures that are detected early during a regular check-up can often be remediated by adding an acrylic resin to the inside of the denture in order to create a closer fit against the alveolar ridge. In addition, unevenly worn down teeth can also be adjusted, replaced, or even built up. Eventually, all dentures will have to be replaced. However, typically if you visit a qualified dentist periodically, you will not have to replace your dentures too frequently.
