Denture Relines, Rebases, And Repairs: When Each Option Makes Sense
Your Dentures Should Fit Comfortably—Every Day
Over time, your gums naturally change shape. This is especially common during the first year after extractions, but gradual shifts continue throughout life. When the fit isn’t quite right, dentures start to rub, loosen, or make eating a challenge. Thankfully, adjustments are normal—and often simple. The key is knowing whether you need a reline, rebase, or repair.
This guide breaks down what each service means, how long it takes, and the symptoms that signal it's time to visit your dentist.
Why Dentures Loosen Over Time
There are three main causes:
- Bone Remodeling
After tooth loss, bone shrinks gradually. Dentures fit the gum tissue, so changes in bone mean changes in fit. - Daily Wear And Tear
Chewing, speaking, and cleaning all add tiny stresses to the material. - Aging Prosthetics
Acrylic weakens with age, especially if exposed to boiling water or harsh cleaners.
Understanding these natural changes helps you choose the right fix.
What Is A Denture Reline?
A reline refits the inside of your denture to match your gums’ current shape.
Types Of Relines
- Soft Reline:
Uses a cushioned, flexible material. Great for recently healed gums or sore spots. - Hard Reline:
Uses durable acrylic. Best for long-term comfort and stability.
Signs You Need A Reline
- Denture moves when you talk
- Sore spots or pressure points
- Needing more and more adhesive
- Food collecting under the denture
- A “floating” lower denture
Relines are the most common fix—and often the easiest.
What Is A Denture Rebase?
While a reline changes the inner surface, a rebase replaces the entire acrylic base of your denture.
The teeth stay the same, but the foundation is rebuilt.
When Rebasing Makes Sense
- Your denture is cracked
- Acrylic is discolored or worn out
- The base feels heavy or bulky
- You want a stronger, fresher prosthetic without replacing everything
Rebases are more extensive than relines but still far more affordable than new dentures.
What Is A Denture Repair?
A repair handles structural issues:
- Cracks
- Fractures
- Chipped or missing teeth
- Broken clasps on partials
Repairs can be simple (fixing a chipped tooth) or more complex (rebuilding a broken base). Quick repairs may be done same-day depending on the office.
How Long Each Option Takes
- Soft reline: often completed in one appointment
- Hard reline: same-day or next-day depending on lab needs
- Rebase: typically 1–2 days
- Repair: varies from 1 hour to 1 day
If you're relying on your denture daily, ask whether the office offers same-day services or temporary solutions.
When It’s Better To Replace Your Denture Entirely
Relines and rebases work beautifully—until the denture is simply too old or too worn out. Replacement may be the smartest choice when:
- The denture is more than 5–8 years old
- The teeth are worn flat from chewing or grinding
- The bite feels uneven or causes jaw discomfort
- The prosthetic looks unnatural or stained
- You want a more modern aesthetic or slimmer design
Dentures have a lifespan; replacing them keeps your smile healthy-looking and functional.
What About Implant-Supported Options?
If your denture has become frustrating no matter how many relines you’ve had, implants may change everything.
Two implant options to consider:
- Snap-In Overdentures:
Removable but incredibly secure. Click into place. - Fixed All-On Implants:
Permanent teeth that stay in place 24/7.
Implants significantly reduce the need for repeated relines.
How To Care For Your Denture After Adjustments
- Clean daily with a denture brush
- Avoid boiling water or harsh chemicals
- Soak overnight in a cleaning solution
- Handle over a soft towel to prevent drops
- Keep regular checkups to ensure long-term fit
Good care extends the life of your denture—and your comfort.
