Dentures should be replaced every 5-7 years. They are not meant to last a life time. Everything that we buy, or every medical product, eventually wears down. This is the result from use creating wear and tear on the device. It is common place for people to replace the tires on their car, have a knee joint replaced, have fillings or caps replaced. Your dentures should also be replaced. After 5-7 years, the monomer ( a component in the acrylic) begins to leach out, resulting in a brittle denture. Loss of bonding to the denture teeth also occur.
There are bony and gingival changes that occur over time. This results in a lack of fit where the denture falls, rocks, needs extra adhesive to keep it up, or is uncomfortable. Often, muscle attachments become "higher" due to bone atrophy and bone height decreasing. These muscles will then lift up your dentures. Denture teeth also wear, over time you have loss of denture tooth "hills and valleys" - the cutting surfaces become worn and your ability to chew decreases.
This patient suffered from multiple broken teeth on her existing denture. We were able to replace them with new good fitting and excellent looking Dentures.
These dentures are about 20 years old, the acrylic pink has changed to a purple color. (When you have gum disease your gums are purple). We gave this patient something to smile about!!!
