Why do dentures lose their fit?
In many cases, the pressure of dentures or partials on the tissues causes gums to get “flabby” and bone to shrink over time. When this occurs, the dentures usually become loose and awkward even when adhesives are applied, much like the way clothes become baggy when one loses weight, and this causes more bone loss and gum problems. With dental implants, bone loss as well as gum erosion are slowed. Unlike dentures, which put pressure and stress on top of the gums and jaw bone, endosseous (“in-the-bone”) implants are actually surrounded by bone and the chewing forces transfer pressures into the bone, much like teeth do. This actually can strengthen the bone and increase bone density, reducing the bone shrinkage seen regularly from dentures.
