Broken Denture? Repair or Replace – How to Know the Difference
A broken denture can cause a lot of stress — especially if it happens suddenly.
Whether your denture has cracked, snapped in half, or lost a tooth, the first question you may ask is:
Can this be repaired… or do I need a new one?
The answer depends on the type of damage, the age of the denture, and the health of your mouth.
This guide explains what to do next, when repairs are possible, and when replacement is the safer long‑term option.
First: What Should You Do If Your Denture Breaks?
Stop wearing it if it is cracked or unstable.
Keep all broken pieces — even small fragments.
Do not attempt DIY repairs.
Contact a denture clinic as soon as possible for assessment.
Should Superglue or DIY Denture Repair Kits Be Used?
It’s very common to consider fixing a denture at home, however this can cause more damage.
Superglue and over‑the‑counter repair kits can:
Contain unsafe chemicals not designed for oral use
Alter the fit of the denture
Make professional repair more difficult
Damage surrounding gum tissue
Even if the denture appears "fixed," it may no longer fit correctly, which can lead to sore spots or long‑term bone changes. A professional repair is always safer.
When a Denture Can Be Repaired
Many broken dentures can be repaired successfully, especially if:
The denture has cracked but pieces align well
A single tooth has come out
A clasp on a partial denture has broken
The denture is relatively new and otherwise fits well
In many cases, denture repairs can be completed quickly, depending on the extent of the damage.
In terms of cost, repairs are generally more affordable than full replacement — provided the base structure is still sound.
When Replacement Is the Better Option
Although at our clinic we try and minimise costs for our patients as much as possible, sometimes a repair is only a temporary solution. A clinician can assess the damage and the fit of the denture.
A reline or replacement may be recommended if:
The fit was already loose before breaking
The denture is very old or worn
There are multiple cracks or repeated fractures
Significant changes in your gums or bone have occurred
In these cases, repairing the denture may not provide long‑term stability. A reline (if applicable) or a new denture can restore proper support, comfort, and function.
Why Dentures Break
Common causes include:
Accidental drops
Natural wear and material fatigue
Ill‑fitting dentures placing stress on the base
Changes in jawbone shape over time
Teeth grinding or heavy biting forces
If your denture has broken more than once, it may indicate that a reline or replacement is overdue.
Is It Dangerous to Wear a Cracked Denture?
Yes — continuing to wear a damaged denture can:
Irritate or cut the gums
Cause infection
Change your bite alignment
Increase bone resorption
Make the denture more difficult to repair
It is always best to have the denture assessed as soon as possible once it becomes unstable, is cracked or broken.
