Denture Rebases and Relines in Edmonton

At Millwoods Denture Clinic, we offer denture rebases and relines to help dentures stay comfortable, functional, and stable as time passes. Even with good care, the mouth naturally changes. Gum tissue can shrink and the jawbone can gradually resorb, which may cause dentures to feel looser than they used to or create pressure along the gumline. These changes can affect chewing, speech, and overall comfort, especially if the denture begins to shift during normal use.


In many situations, a rebase or reline can improve stability without replacing the entire appliance. Updating the base or the tissue-facing surface helps the denture adapt to your current gum contours, which can reduce irritation and help the denture seat more securely. If you are noticing soreness, looseness, or changes in how your dentures feel, it may also be helpful to review denture repairs to understand the difference between a fit update and a repair related to cracks or broken teeth.

Rebase and Reline Explained

Rebasing and relining both aim to improve comfort and fit, but they correct different parts of the denture. The right choice depends on the condition of the denture base, how your gums have changed, and what is causing the looseness or discomfort.

Denture Rebase

A denture rebase replaces the entire pink acrylic base while keeping the existing denture teeth when appropriate. This option is often recommended when the base has become worn, cracked, unstable, or no longer provides reliable support, but the tooth portion is still in good condition. Rebasing refreshes the foundation of the appliance, which can improve strength, stability, and comfort while avoiding a full replacement.

Denture Reline

A denture reline updates the inner, tissue-facing surface so it matches the current shape of your gums more closely. This is commonly recommended when dentures begin to feel loose, rock during chewing, or create sore spots because the mouth has changed gradually over time. By adding new material to the tissue side of the denture, a reline can reduce movement and improve day-to-day comfort without replacing the entire appliance.

We may recommend either a soft or hard reline depending on comfort needs and tissue health. If the gums are tender or easily irritated, a cushioned option may be more comfortable. You can learn more about this approach in soft liners. If tissues are healthy and the goal is a firmer, updated fit that holds shape well, a hard reline may be recommended.

Signs It May Be Time for an Update

If your dentures slip, feel uncomfortable, or no longer fit as they once did, it may be time to consider a rebase or reline. Common signs include movement while eating or speaking, recurring sore spots, pressure along the gumline, or avoiding certain foods because the denture does not feel stable.


Many patients benefit from having their dentures checked about every two years to monitor fit and comfort, although timing can vary based on tissue changes and wear patterns. Addressing fit changes early can help reduce irritation and lower the chance of bigger issues developing over time.
