Can You Glue Broken Dentures? The Truth About DIY Repairs
So, your dentures just snapped. Maybe you dropped them in the sink, bit down on something a little too hard, or they simply cracked from years of wear. Either way, you’re staring at the pieces, wondering: Can I just glue my dentures back together?
Short answer? No, not if you want them to last.
A lot of people immediately reach for super glue, thinking it’s a quick fix. But here’s the problem—most super glues contain toxic chemicals that you do not want in your mouth. Even if you find a so-called “non-toxic” glue, it won’t bond properly to denture material. The result? A weak, brittle fix that’s bound to break again—probably at the worst possible time.
What Happens When You Use Super Glue on Dentures?
- Chemical Exposure – Most glues contain cyanoacrylate, which isn’t meant for prolonged oral contact. You could end up with mouth irritation, allergic reactions, or worse.
- Weak Bonding – Super glue isn’t designed for the flexibility and moisture that dentures experience daily. It might hold for a bit, but it won’t last.
- Impossible Professional Repairs – If you ever decide to get your dentures fixed properly, glue residue can make professional repairs nearly impossible.
So, what’s the right move? Use a denture repair kit instead. These kits contain a dental-safe bonding material that’s designed for dentures—no toxic chemicals, no crumbling fixes. Dentemp Repair Kit is one of the best options out there, and it’s way safer than dousing your dentures in glue.
The Best Way to Repair Broken Dentures at Home
Alright, so now that we’ve ruled out super glue, let’s talk about how to actually fix your dentures the right way. If the break isn’t too severe, a denture repair kit can do the trick until you see a pro.
Step-by-Step Guide to Fixing Broken Dentures at Home
- Clean the Broken Pieces – Use warm water and a mild denture cleaner to remove any debris. Do NOT use toothpaste—it’s too abrasive.
- Dry Completely – Water messes with the bonding process, so make sure everything is 100% dry before moving on.
- Apply the Repair Material – Follow the exact instructions from your denture repair kit. Typically, you’ll mix a bonding agent and carefully apply it to the broken edges.
- Hold in Place – Press the pieces together firmly and hold for the recommended time (usually a few minutes).
- Let It Cure – This is the hardest part—waiting. Most kits require several hours to fully cure, so resist the urge to wear them too soon.
When a Home Fix Won’t Cut It
Sometimes, a denture repair kit isn’t enough. If your dentures:
❌ Have multiple cracks
❌ Are missing pieces
❌ Break repeatedly
…it’s time to get a professional repair or consider replacements. If your dentures keep loosening or breaking, it might be worth looking into implant-retained dentures, which are far more stable. Check out this guide on tightening implant-retained dentures at home if that’s something you’re dealing with.
Is Super Glue Safe for Denture Repair? Expert Advice
I get it—super glue is cheap, fast, and sitting right there in your junk drawer. But before you start squeezing that tube onto your broken dentures, let’s get one thing straight: Super glue is NOT a safe option for denture repair.
Why Super Glue and Dentures Don’t Mix
🔴 Toxicity Risks – Even if the label says “non-toxic,” super glue isn’t meant for prolonged oral exposure. Over time, it can break down and release harmful chemicals into your mouth.
🔴 Brittle Bonding – Dentures need flexibility to handle chewing and everyday use. Super glue dries rock-hard, making the repair fragile and prone to breaking again.
🔴 Moisture Weakens the Bond – Your mouth is constantly wet, and moisture breaks down super glue over time. The repair might hold for a few days, but it’s not going to last.
🔴 Ruins Professional Repairs – If you glue your dentures yourself, you might make it impossible for a dentist to fix them later. The glue seeps into the material, making it harder to bond correctly.
What About “Non-Toxic” Super Glue for Teeth?
Some people look up “non-toxic super glue for teeth” hoping to find a safe alternative. The truth? There really isn’t one. Even glues labeled as “safe” are meant for small, temporary fixes—like sealing a broken nail—not for something that sits in your mouth all day.
If you’re dealing with repeated denture cracks, it might be time to look into stronger, long-term solutions like implant-retained dentures. They won’t crack like traditional dentures, and they last much longer. If you’re curious, check out this guide on All-on-4 implant-retained dentures to see if they’re a better option for you.
Choosing the Right Glue for Dentures (What Actually Works?)
So, if super glue is out, what should you use? The best option is a denture repair kit that’s made specifically for this kind of fix. These kits contain a medical-grade bonding agent that’s safe for oral use and actually holds up to daily wear.
What to Look for in a Denture Repair Kit
✅ FDA-approved & denture-safe – Anything not designed for dentures shouldn’t be in your mouth.
✅ Strong but flexible bond – Dentures need a little flex to handle chewing pressure.
✅ Easy-to-use formula – Some kits require mixing, while others come pre-made. Choose what works for you.
One of the top-rated repair kits out there is Dentemp Repair Kit—it’s affordable, reliable, and actually works without the risks of super glue.
Denture Repair Kits vs. DIY Household Glues
| Feature | Denture Repair Kit | Super Glue / Household Glue |
|---|---|---|
| Safe for oral use? | ✅ Yes | ❌ No |
| Long-lasting bond? | ✅ Yes | ❌ No |
| Flexible when chewing? | ✅ Yes | ❌ No |
| Moisture-resistant? | ✅ Yes | ❌ No |

If you want your dentures to last longer after a repair, proper cleaning is key. A lot of people don’t realize that cleaning dentures the wrong way can weaken them over time. If you’re not sure if you’re cleaning yours properly, check out this guide on how to clean implant-retained dentures—it covers everything you need to know.
What to Do If Your Denture Repair Fails
Let’s say you’ve tried a denture repair kit, followed all the steps, and… boom, it breaks again. Now what?
First off, don’t panic. Dentures go through a ton of stress daily, and if they keep cracking, it usually means something bigger is wrong. Here’s what to do next:
Signs Your Denture Repair Isn’t Holding Up
❌ It feels loose or wobbly – A solid repair should feel stable. If yours doesn’t, the bond isn’t strong enough.
❌ The crack reappears in the same spot – This means the dentures are under pressure in a way they weren’t before.
❌ You notice small hairline fractures forming – This is an early warning sign that a full break is coming.
If your repair keeps failing, it’s probably time to visit a dentist for a professional fix. In some cases, they can reinforce the structure instead of replacing them completely.
But if your dentures keep snapping, loosening, or breaking beyond repair, you might need a stronger long-term solution. If that’s the case, check out this guide on broken denture repair options—it breaks down all the best solutions for long-term fixes.
How to Prevent Dentures from Breaking Again
Fixing broken dentures is one thing, but keeping them from breaking again? That’s the real goal. If you don’t want to go through this mess every few months, here’s how to extend the life of your dentures:
1. Handle Them with Care
Most breaks happen because dentures get dropped in the sink or on the floor. When cleaning them, place a towel in the sink or fill it with water so they have a soft landing if they slip.
2. Store Them Properly
Never leave dentures out to dry. Dentures should be kept in water or a denture solution when you’re not wearing them. Dry dentures become brittle and more likely to crack.
3. Watch Out for Jaw Clenching and Grinding
Believe it or not, grinding your teeth can put enough pressure on your dentures to weaken them over time. If you wake up with sore jaws or headaches, you might be grinding your teeth in your sleep without even realizing it. This guide on teeth grinding and jaw clenching explains why it happens and how to stop it.
4. Keep Dentures Clean (The Right Way)
Many people think they’re cleaning their dentures properly, but toothpaste and hot water can actually weaken them. Use a gentle denture cleaner and a soft brush to avoid unnecessary wear. If you’re not sure if your cleaning routine is safe, check out this guide to cleaning implant-retained dentures.
When to Fix, When to Replace
So, now you know the truth—super glue is NOT the way to fix broken dentures, but there are safe, effective repair options out there. If your dentures have a minor crack, a denture repair kit like Dentemp can be a quick and reliable solution. But if your dentures keep breaking, it’s a sign of a bigger problem.
Here’s a simple rule of thumb:
✅ Fix Your Dentures If…
- The break is minor (small crack, single tooth loose).
- The repair kit holds well, and they feel secure.
- You need a temporary fix before seeing a dentist.
🚨 Replace Your Dentures If…
- They keep breaking in the same spot.
- You’re dealing with multiple cracks or missing pieces.
- They don’t fit right anymore, making eating/talking uncomfortable.
If your dentures keep giving you trouble, it might be time to look at stronger, longer-lasting solutions—like implant-retained dentures. They stay in place without adhesives, don’t break as easily, and feel more like real teeth. If you’re curious, check out this guide to All-on-4 dental implants to see if they’re right for you.
At the end of the day, taking care of your dentures the right way is the best way to keep them from breaking in the first place. That means gentle cleaning, proper storage, and avoiding stress from clenching or grinding (which you can read more about here).
The Bottom Line?
If your dentures break, skip the super glue and go for a real fix. A good denture repair kit can save the day, but if your dentures are constantly cracking, it’s probably time for an upgrade. Either way, taking care of your dentures properly will save you from the hassle of dealing with broken ones again.
