Getting your denture refitted is essential to maintain the correct fit, preserve the bone structure, and to avoid premature wear to the teeth. The older the denture is, usually the looser it will be in your mouth. There are ridges in your mouth that help stabilize a denture. These ridges naturally shrink over time making the denture fit improperly. Dentures should be refitted every two to three years to restore optimum fit and function. Refitting effects only the fit of your denture and will not change the appearance or address any wear of the denture teeth.
