Denture Replacements
The normal lifetime of dentures is about 5 to 10 years, but this can vary widely depending on the patient. Over time, dentures may need relining, rebasing, or replacing. Relining is when the dentist adds new material to the underside of the denture base to fit your gums. Rebasing is when a new base is made using the existing denture as a model. The artificial teeth from the old denture are used on the new base.
The mouth changes naturally with age. Jaws may line up differently as bones and gum ridges recede and shrink. At some point your dentures will no longer fit well, and they will have to be remade. It is important to replace worn or ill-fitting dentures before they cause problems. Your dentist will let you know where it is time to replace your dentures.
