Will dentures last a lifetime?
With proper care, a set of dentures should last a long time. However, it's likely that over time dentures will need to be relined, remade or rebased, not because of problems with the apparatus, but because of the natural changes aging causes in your mouth. Bone and gum ridges can shrink or recede, making jaws line up differently. Shrinking ridges can make dentures fit less securely.
Loose dentures can lead to health problems like sores and infections. A loose denture also can make chewing difficult and uncomfortable and can change your facial features. To make a rebased denture, the dentist uses the existing denture teeth and makes a new denture base.
These are some of the reasons why it's important to remain vigilant about your oral health and make regular trips to the dentist even after you begin wearing dentures. Every morning, for instance, you should brush your gums, tongue and palate with a soft-bristled brush before you put in your dentures. The brushing removes plaque and stimulates blood circulation in your gums. A balanced diet that provides proper nutrition is also important for denture wearers. Ask your dentist for advice on making your dentures last.
