Loose dentures are usually a sign your gums have changed shape. A reline refits the base to your mouth. Here’s how it works and what it costs.
By the FixUrSmile Dental Lab team · Updated September 2026
A denture reline adds new material to the fitting surface of a denture or partial so it matches the current shape of your gums. Over time, gums and bone naturally change, especially after tooth loss, which can make an appliance feel loose or cause sore spots.

| Hard reline | Soft reline | |
|---|---|---|
| Material | Rigid acrylic | Pliable, cushioning liner |
| Best for | Most routine fit changes | Sensitive or sore gums |
| Typical lifespan* | Over two years | About one to two years |

A professional reline at a dental office can cost about $400 to $600, according to Dentaly. At-home reline kits cost much less, often under $30, but they carry real risks.
Home reline kits can be tempting, but applying too much or uneven material can change your bite, create pressure points, and make a professional reline harder later. Many dentists advise using them only as a short-term fix. If your appliance is loose, have it evaluated.
If a partial is cracked, worn, or missing teeth, or if a reline would cost close to a new appliance, replacing it may make more sense. FixUrSmile custom partials start at $245 and are made from new impressions of your current mouth, so they fit the way your gums are now. Compare options in our partial dentures guide.
A reline adds a new layer of material to the fitting surface of your denture or partial so it hugs your gums again. A rebase replaces the entire pink base while keeping the existing teeth. A rebase is more involved and is usually suggested when the base itself is worn, cracked, or stained but the teeth are still in good shape.
If your partial is several years old, loose in more than one spot, or made of a flexible material that can’t be relined easily, a new partial may be the simpler fix. FixUrSmile makes flexible and acrylic partials from at-home impressions, so you can keep wearing your current one while the new one is made.
Some dentists recommend hard relines about every two years, but it depends on how your mouth changes. Get it checked if it feels loose.
A professional reline can cost about $400 to $600. At-home kits cost less but can cause fit problems.
Flexible partials are hard to reline, so a significantly loose flexible partial is usually replaced.
It depends on the appliance. FixUrSmile custom partials start at $245, which can be comparable to or less than a professional reline.
