Broken, worn or ill-fitting dentures need not always be replaced. In fact, your denturist can assess very quickly if you’re a candidate for a rebase, reline or repair. In the case of repairs, your Denturist can often offer same-day service. 
Rebase
Rebasing is usually done when the denture teeth have not worn out in comparison to the denture base material. It is a process of retrofitting dentures by replacing all of the acrylic denture base with new acrylic, which provides a stable denture without replacing the denture teeth.
Relines
This consists of adding new base material to the tissue side of a denture so it fits properly. Your Denturist will need to take an impression inside your existing denture. Relining affects only the fit of your denture and will not change the appearance. Relines are required when tissue changes occur due to resorption (shrinkage).
This can be due to:
- Loss of weight
- Loss of teeth
- Loss of bone
- Ageing
- Disease or illness
Repairs
In most cases, your Denturist can restore an existing broken or cracked denture to its original state. Repairs may be required when breakage or chipping occurs, when one or more teeth need to be added to an existing denture (due to tooth extraction), or because of wear and tear.
Most repairs can easily be done in one day. If your denture requires a repair, it may be indicative of underlying problems, including age of the denture, worn teeth or poor fit. Your Denturist is the professional who can best explain how to prevent denture breakage from occurring.
