This consists of adding a new base material to the tissue side of the denture (the inner side) so that it fits properly. An impression is taken inside your existing denture and in most cases the reline can be completed on the same day.
Relining only affects the fit of the denture and will not change the appearance.
Relines are usually required when the gum tissue changes due to shrinking. This could be due to loss of weight, loss or extraction of teeth, aging, or disease or illness.
