After your teeth are extracted, your gum continues to shrink as time goes on. This results in a denture that can be loose or ill-fitting. A reline fills in the gap between your denture and your gums with new hard acrylic to restore it’s stability. It is recommended to get a reline on a full denture 6-12 months after extractions and checked every two years after that.
We also have the option of a soft reline available which can either be temporary or permanent. The temporary soft reline is a tissue conditioner used to prepare the gums under the denture for the hard reline, allowing ulcers or sore spots to heal. The soft reline only lasts 6-8 weeks after which it should be made into a permanent material. The material is not designed to last a long time.
Permanent soft liners are a last resort for patients whose mouths cannot tolerate the hard acrylic due to bony ridges. They are not as permanent as hard relines, requiring replacement after two years.
A denture may be able to be relined if:
The denture no longer fits, it slips, or falls down
The age and condition of the denture is good
The original denture was an immediate denture (made right after teeth were extracted). This means that where the gums and bone natural teeth were removed has now shrunk/resorbed causing a gap between the tissue and denture, causing looseness
What a reline does NOT do:
It does not change the teeth or its surface. The teeth will remain the same
A reline only makes the fitting surface of the denture fit more snuggly and can increase the suction of the upper denture
