Denture relines and rebases provide an existing denture with an updated, more accurate fit. Because your gums are always evolving, denture wearers are expected to have a reline/rebase every 2-3 years to maintain comfortable fit and function.
Denture relines and rebases involve replacing the pink acrylic part of the denture, and processing it with new, high impact acrylic material. This also helps keep the denture strength at its highest and reduces the chance of future cracks or breaks. Relines only affect the fit of your denture and will not change its appearance or aesthetics.
