How long do dentures last?

A well-made denture typically lasts 5 to 8 years before the fit and bite deteriorate enough to warrant replacement. With regular relines every 2–3 years, you can extend the comfortable life of your denture significantly. Signs it's time for a new set include persistent looseness, worn-flat teeth, repeated cracking, changes in your facial shape, or soreness that won't settle. Chris advises each patient on when maintenance is enough and when replacement is the better investment.
