Dentures can still be perfectly solid after ten or twenty years, but that does not answer the question: How long do they last? The mouth changes constantly. The bones get smaller with age. If you have natural teeth, then the distance between your nose and your chin stays constant. If you have dentures, this distance gets smaller as the bones supporting your dentures shrink. Your upper teeth become less visible when you smile because of this shrinkage. The lower half of your face gets shorter for the same reason. New dentures can compensate for these changes. Your smile will be fuller and more natural, and your face will look younger. Wait too long, and the changes will be much larger and harder to adapt to. So the real question is: How long before my face needs to be supported better by new dentures? The answer: Five to eight years.
