A denture reline refits the inside of your existing denture so it better matches the current shape of your gums. It may be recommended when dentures become loose, shift while eating or speaking, trap food underneath, cause sore spots, or require more adhesive to stay secure.
There are three main types of denture relines: hard, soft, and temporary. The right option depends on the condition of your gums, how much your mouth has changed, and the condition of your existing denture.
A reline can improve fit and comfort without replacing the entire denture, but your denturist should first assess whether a reline, adjustment, or new denture is the most appropriate solution.
Dentures can fit comfortably at first but gradually become loose as your gums and jaw change over time. You may notice movement when speaking or eating, food getting underneath, or new sore spots.
That doesn’t always mean you need new dentures. During a denture consultation, a denturist can assess the fit and determine whether a denture reline could help. A reline reshapes the fitting surface of your existing denture so it better matches your gums and feels more secure.
In this guide, we’ll explain what a denture reline is, when you may need one, the different types, and what to expect from the process.
What Is a Denture Reline?
A denture reline is a procedure that resurfaces the inside of an existing denture so it fits more closely against the current shape of your gums. New material is added to the fitting surface—the part of the denture that rests directly against the tissues in your mouth.
The teeth and visible portion of the denture generally remain the same. Instead, the surface underneath is modified to compensate for changes that have occurred in your gums and jaw since the denture was originally made.
Think of it as refitting the denture to your mouth rather than replacing the entire denture.
After teeth are lost, the jawbone and gum tissues gradually change shape over time. Your denture, however, stays the same. This can eventually create small spaces between the denture and the tissues supporting it.
Relining helps reduce these spaces so the denture sits in closer contact with your gums again.

When Do You Need a Denture Reline?
A denture shouldn’t regularly move around, create painful pressure points, or make everyday activities unnecessarily difficult. Changes often develop gradually, however, which means you may adjust to a worsening fit without realizing how much it has changed.
Dentures that feel loose or move when you speak.
Clicking or shifting while eating.
Food frequently becoming trapped underneath the denture.
New sore spots or areas of irritation.
Difficulty chewing foods you previously ate comfortably.
Needing more denture adhesive to keep your dentures secure.
A noticeable change in fit or how the denture sits against your gums.
Your dentures no longer feel as comfortable as they once did.
A loose denture isn’t something you simply have to accept. A denturist can assess whether the problem can be corrected with a reline or whether another adjustment or replacement would be more appropriate.
What Are the Different Types of Denture Relines?
Not every denture or mouth requires the same type of reline. Depending on the condition of your gums, your denture, and how long the new lining needs to last, your denturist may recommend a hard, soft, or temporary reline.
Hard Denture Reline
A hard reline uses a firm acrylic material similar to the material used in the denture base. It creates a durable new fitting surface and is generally intended as a longer-term solution.
Patients whose gums are healthy enough to comfortably tolerate a firm denture base and whose existing denture is otherwise in good condition.
Durability and a secure long-term fit.
Soft Denture Reline
A soft reline uses a more flexible, cushioning material on the fitting surface of the denture. The softer material can reduce pressure against sensitive tissues and make the denture more comfortable to wear.
Soft liners generally require more maintenance and may need replacement more frequently than a hard acrylic reline.
People with tender gums, thin tissues, recurring sore spots, or difficulty tolerating a rigid denture base.
Additional cushioning and comfort.
Temporary or Tissue-Conditioning Reline
A temporary reline uses a soft material intended to give irritated or healing tissues time to recover. Rather than serving as the final long-term solution, it can be used while the mouth stabilizes before another treatment is completed.
Inflamed or irritated gums, healing tissues, or situations where the shape of the mouth is still changing.
Provides short-term cushioning while allowing the tissues to recover.
What Happens During a Denture Reline?
One reason people put off having loose dentures checked is uncertainty about what the procedure involves. A professional denture reline is generally much simpler than having an entirely new denture made. The exact process depends on the type of reline and whether laboratory work is required, but it generally involves the following steps.
Your Denture and Mouth Are Examined
Your denturist first examines your gums, oral tissues, bite, and existing denture. This helps determine why the fit has changed and whether the denture is still in suitable condition to be relined.
An Impression of Your Mouth Is Taken
Impression material is placed inside the denture and the denture is positioned in your mouth. This records the current contours of the tissues that support it.
The Fitting Surface Is Resurfaced
Using the impression as a guide, the inside of the denture is modified and new lining material is added so the base corresponds more closely to the current shape of your mouth.
Depending on the type of reline, this may be completed in the clinic or require laboratory processing.
The Fit and Bite Are Checked
Once the reline is complete, the denture is placed back in your mouth. Your denturist checks the fit, comfort, stability, and bite and makes adjustments where necessary.
The result should be a denture that sits more securely and comfortably against your gums without having to replace the entire appliance.
How Often Should Dentures Be Relined?
There isn’t one schedule that applies to everyone because the rate at which your gums and jaw change can vary.
As a general guideline, dentures may need to be relined every 1 to 2 years, although some people may need one sooner and others may go longer between relines. Changes can happen more quickly during the first year after tooth extractions as the gums and underlying bone continue to heal and reshape.
Rather than relying only on a set timeline, pay attention to how your dentures fit. If they begin to feel loose, move while you speak or eat, cause sore spots, or require more adhesive than usual, it’s a good idea to have them assessed.
Regular denture checkups can also help identify changes in fit before they become uncomfortable.
Dentures may need to be relined approximately every 1 to 2 years, although some people may need a reline sooner while others may go longer depending on how their mouth and denture fit change over time.
Denture Reline vs. Adjustment: What’s the Difference?
A denture reline and a denture adjustment can both improve the fit and comfort of your dentures, but they address different problems.
An adjustment makes a small change to a specific area of the denture, such as reshaping a spot that is rubbing against your gums or creating too much pressure.
A reline changes a larger portion of the denture’s fitting surface by adding new material so it better matches the current shape of your gums. In general, an adjustment is used for a localized problem, while a reline is more appropriate when the overall fit of the denture has changed.

| Material added? | Usually not | Yes, new lining material is added |
| Simple way to think about it | Fixes a problem spot | Refits the denture to your mouth |
Can You Reline Dentures at Home?
Denture reline kits are available over the counter, but they aren’t equivalent to a professional reline.
A professional reline begins with an assessment of why the denture has become loose. A denturist can examine your oral tissues, evaluate your bite, assess the condition of the denture, and create an impression based on the actual shape of your mouth.
An at-home kit cannot determine whether the problem is caused by normal tissue changes, an issue with the denture itself, or something in the mouth that requires attention.
Adding material incorrectly can also alter how the denture sits or how your upper and lower teeth meet.
For those reasons, a loose or uncomfortable denture is better assessed professionally before deciding how it should be corrected.
A loose denture doesn’t always mean the lining is the problem. Changes in your mouth, bite, or the denture itself can affect how it fits, so it’s worth having the cause assessed before adding or removing material.
What Should You Expect After a Denture Reline?
Your dentures will usually feel noticeably different after a reline because the new fitting surface makes closer contact with the current shape of your gums. They may initially feel tighter or more snug than you’re used to, particularly if you had been wearing loose-fitting dentures for some time.
A snugger, more secure fit with less slipping or lifting.
Less movement when speaking or eating, which can make the denture feel more stable.
Improved comfort as pressure is distributed more evenly across the supporting tissues.
Less food getting underneath the denture because there are fewer gaps between the denture and gums.
Reduced reliance on denture adhesive if you were previously using it to compensate for looseness.
Conclusion
Your mouth naturally changes over time, but your dentures don’t change with it. When that difference begins causing looseness, movement, food trapping, or sore spots, a denture reline can reshape the fitting surface of your existing denture so it better matches your gums again.
The important part is determining why your denture no longer fits properly. Sometimes a simple adjustment is enough; in other situations, a hard, soft, or temporary reline—or eventually a new denture—may be the better solution.
If your dentures don’t feel as secure or comfortable as they used to, Orléans Denture Clinic can assess the fit of your dentures and recommend the appropriate next step.
Get Your Denture Fit Checked
If your dentures are moving, causing sore spots, or simply don’t feel as comfortable as they once did, you don’t have to wait until the problem gets worse. Have your dentures assessed to find out whether an adjustment, reline, or another solution can restore a more comfortable fit.
