What is a denture base?
The denture base is the supporting part of a removable denture. It rests against oral tissues and carries the artificial teeth. Its shape, extent and material depend on the planned restoration.

Beneath the artificial teeth
The base connects the artificial teeth to the rest of the denture. Many bases are made of pink acrylic resin; some designs also include metal components.
Support is different from retention
The base rests on denture-bearing tissues. Distribution of chewing forces and retention also depend on remaining teeth, clasps or other attachments.
When the fit changes
Jaw tissues can change over time. Sore spots, rocking or fracture need assessment. Relining, repair or replacement is decided for the individual denture.

Often confused
Base or artificial tooth?
The base provides the supporting tissue-facing part. Denture teeth replace visible crowns and chewing surfaces.
Quick answers
Is every base made of acrylic?
No. Acrylic resin and, in some designs, metal are used. The construction and its requirements determine the choice.
Is relining the same as replacing the base?
No. Relining adds material to the tissue-facing surface. Rebasing replaces the entire denture base material; neither procedure suits every denture.
Can I file down a sore spot myself?
No. Professional adjustment helps avoid damaging the fit or changing how forces are distributed.
At the practice
For the appointment
You can bring this question to your appointment:
Does my denture base rest evenly, or does its fit need adjustment?
An examination can clarify the finding and any need for referral.
