If your denture has cracked or snapped, the single most important rule is do not try to glue it yourself. Household and super glues are not safe for the mouth, rarely hold, and often make a proper repair harder or impossible. A broken denture is usually fixable, and in many cases repaired the same day, but it needs the right materials and a professional. Keep all the pieces, take the denture out, and arrange a repair as soon as you can.
Here is what to do, what to avoid, and how repairs and relines work.
Key takeaways
- Do not use super glue or household glue on a denture. It is unsafe and can ruin the fit.
- Keep every piece, including small fragments, and store the denture safely.
- Most breaks are repairable, often the same day, by a dentist or dental prosthetist.
- Repeated breaks or a loose denture often signal a poor fit that needs a reline or replacement.
- A denture that no longer fits can cause sore spots, so avoid forcing a damaged one back in.
First steps when a denture breaks
Stay calm and act carefully. Take the denture out of your mouth to avoid swallowing or inhaling a loose piece, and rinse it gently. Gather all the fragments, even tiny ones, because they help the technician rebuild it accurately. Store the pieces somewhere safe, ideally in a container, and keep the denture moist if it is a full acrylic plate. Then contact your dentist or a dental prosthetist to arrange a repair.
| Do | Do not |
|---|---|
| Remove the denture and keep all pieces | Glue it with super glue or household adhesive |
| Rinse gently and store safely | File or sand sharp edges yourself |
| Call for a professional repair | Keep wearing a sharp or ill-fitting piece |
| Use the spare denture if you have one | Attempt a DIY repair kit as a lasting fix |
Why not super glue or DIY kits
It is tempting to reach for glue, but it causes more problems than it solves. Super glue is not food-safe and can irritate or harm the soft tissues of the mouth. It also sets in the wrong position easily, so the two halves no longer line up, which changes the fit and can create pressure points and sore spots. Once glue is on the break, a technician often has to grind it away or may not be able to bond the surfaces cleanly, turning a simple repair into a remake. Chemist DIY repair kits have the same drawbacks and do not address why the denture broke in the first place.
How professional repairs work
A dentist or dental prosthetist repairs the denture with proper dental acrylic, aligning the pieces so the bite and fit are correct. Many straightforward repairs, such as a cracked plate or a broken-off tooth, can be done the same day, sometimes while you wait. A repair not only bonds the break but checks that the fit has not shifted, because a denture that is repaired out of alignment will keep causing problems. If a clasp on a partial denture has snapped, that can usually be repaired or replaced too.
Why did it break?
Dentures break for a few common reasons, and the cause matters because it guides whether a repair alone is enough. A denture dropped on a hard surface may simply have a clean fracture. But a denture that cracks down the middle repeatedly, or one that has become loose, is often a sign the fit has changed as the gums and jawbone naturally shrink over time. In that case the denture flexes with every bite and eventually fails. This is where a reline or a new denture is the real solution. Our guide to relines versus new dentures explains the difference, and denture costs are covered separately.
Repair, reline or replace?
A one-off clean break usually just needs a repair. Frequent breaks or a denture that has felt loose for a while often needs a reline, which refits the inner surface to your gums, or a full replacement if it is worn out. If you are also considering more stability, implant-retained options exist, as covered in our guide to implants versus bridges versus dentures. A general dental check will sort out which path fits your situation.
Is a broken denture an emergency?
It is rarely a medical emergency, but it can be an urgent inconvenience, especially if it is your only denture. Sharp edges can rub the gums or cheek, so it is better not to wear a broken piece if it is uncomfortable. If a fragment has caused a cut or you cannot eat, contact a dentist promptly.

Frequently asked questions
Can I use super glue on my denture?
No. Super glue is not safe for the mouth, rarely holds, and usually sets the pieces out of alignment, which can turn a simple repair into a full remake. Keep the pieces and see a professional.
Can a broken denture be fixed the same day?
Often yes. Many simple repairs, such as a cracked plate or a broken tooth, can be completed the same day, sometimes while you wait, by a dentist or dental prosthetist.
Why does my denture keep breaking in the same place?
Repeated breaks usually mean the fit has changed as your gums and jaw have shrunk over time, so the denture flexes and fails. A reline or a new denture is generally needed, not just another repair.
Can I still wear my denture if it is cracked?
Only if it is comfortable and not sharp. A cracked or ill-fitting denture can rub and cause sore spots, and continuing to wear it can worsen the damage. When in doubt, leave it out and seek a repair.
Who repairs dentures?
A dentist or a registered dental prosthetist can repair dentures using dental-grade materials. They can also assess whether a reline or replacement is the better long-term option.
The takeaway
A broken denture is usually an easy fix, but only with the right materials, so resist the urge to use super glue. Keep the pieces, take the denture out, and arrange a professional repair, which is often same-day. If it keeps breaking or has felt loose, a reline or new denture is the real answer.
