Dentures are built to be durable, tough and long-lasting, but like real teeth, they’re prone to damage.

This can be an annoying and expensive inconvenience, especially while eating or speaking. But is it possible to repair your broken dentures on your own?

Is there any kind of glue that can be used to keep your teeth looking their best?

First off, no matter which type of glue you choose to use, it’s important to remember two things:

  1. The glue you choose should be waterproof.
  2. The glue you choose, no matter how strong it is, is just a temporary fix. At some point, you should still consult a professional dentist to have dentures repaired.

A Denture Repair Kit can be used to repair dentures, and contains the best type of glue to use for anyone with false teeth that have been damaged. Acrylic resin is expensive and intended for use by dentists, but it’s the strongest type and it’s especially for dental use, unlike super glues or crazy glues.

Acrylic resin is very strong, but it will bond quickly to other materials. If you decide to use it, always make sure you have a clean workspace with no debris or garbage in the way.

Avoid touching the resin with your bare hands until it’s completely dry.

Don’t overdo the use of resin, because it can make your mouth look lumpy and bulged outward when you insert your teeth back in.

Only use the amount you need.

Although it might sound bizarre, in an emergency you can use Super-glue or Krazy Glue to temporarily fix a broken tooth on a pair of dentures. This is not as strong as resin, but will hold up until you next see your dentist.

Like the resin, Super-glue is fast bonding and will damage skin, so don’t touch it with your bare hands, and keep it away from any other material in your household.

Never put your dentures back into your mouth until after the glue is 100%, rock-solid dry. Krazy glue is notorious for bonding directly to skin, and often requires a medical doctor to remove it, which can be painful and embarrassing.

Which glue is the safest and strongest for dental repair?

Dental-grade resin is the safest and strongest, bar-none, but if you’re on a budget, it can be quite costly.

You may want to just visit your dentist and have your teeth professionally repaired. Avoid softer glues like school glue, airplane model glue, glue gun glue and ceramic glue.

These glues, often found in most North American households, might be tempting to use.

However, they each have specific purposes that don’t mix well with dental products. Using these types of glues will only damage your dentures even further.

If you’re uncomfortable about using glue on your dentures, the alternative is a denture repair kit. Available at most drugstores as an over-the-counter product, these little kits come with instructions, safety tips, small single-use epoxy bottles and everything else you need to fix your dentures on your own.

If you’ve never had to repair your dentures before, this is a good choice. Most denture repair kits contain dental-grade glue, but it’s already squeezed out for you in proper measurements, so you don’t have to worry about using too much glue if you’ve never tried it before.

Although glues can repair dentures, they don’t always work for other dental products. Avoid using glue on bite plates, braces, InvisAlign products, dental implants, gold teeth, damaged natural teeth or any other kind of tooth/tooth product without talking to your dentist first.

Many of these products contain plastics that can react badly with glue. Glue should never be applied directly to real teeth, even broken ones. It should not be applied to loose teeth on children.

If you’ve damaged your real teeth and it’s a serious injury, visit an emergency room or talk to your dentist. Talking to dental professionals is the best way to see what your options are.

Glue is only the right choice in some cases.

Always read the safety precautions on the back of any packaging that comes with the glue. Avoid using glue for denture repair if you’ve had an allergic reaction to it in the past.

  1. You cannot fix broken dentures with superglue because it will not bond well with your dentures. Superglue could damage your dentures and may lead to gum inflammation. Also, superglue dissolves in water and tastes terrible. Thanks for sharing this article with us.

    1. I strongly disagree. I’ve used super glue to fix my dentures and have had no side effects, bad tastes or glue dissolving in water. My repair has lasted for years until I dropped them today and broke the same piece. I plan to superglue them again later today.

      1. Hi Hopefully wish you are doing well, and happy Thanksgiving.
        Could you please provide the strongest glue you used to fix your denture for years as you mentioned, I really I wanna do it because I tried so many glues but it failed to fix my problem .
        Your kind prompt response is highly appreciated.

        1. It’s by locktite and comes with an activator it’s like crazy glue but way better I used this to glue my broken dentures and it lasted 15 years.

        1. I would like to know if anyone has used fiberglass resin to repair a cracked upper denture and how well has it worked?

      2. how you did it that last a year, i really respect your work. myself also used super glue to fix my broken denture and so far the longest it can last is 6 months only.

      3. Super Glues are primarily Cyanoacrylates. The Cyano means that there is Cyanide in the glue, if you want to put Cyanide in your mouth go right ahead. The Cyanide is taken up into the tooth via tubules and will eventually kill the tooth.

        Now certain glues are based on other compounds, or your tooth might be dead already (hence people saying it works) but I wouldn’t recommend telling people to put superglue in your mouth.
        If you’re that desperate Glass Ionomer is the stuff to use.

    2. MY dentures broke in half only 6 months after the were made, Thanks Western Dental! I used a gel super glue and they held up for well over a year, until yesterday. My budget for Western Dental is that I have a 650 dollar out of pocket to pay before insurance kicks in. Off to buy more Precision Super gel glue.

  2. I just got some new dentures and one of the teeth have come out two times while being repaired by a dentist. Each time I take the plate back to the dentist they keep it for a couple of weeks and I have nothing to eat with. So evidently my dentist is using a poor glue substitute, and it’s not bonding with the tooth, because the tooth is popping out clean as if what was on the tooth to keep it In place has been completely dissolved after eating for about a week each time. So I’m thinking about trying something other than a professional dentist my next go round, which is today. Th

  3. Please please PLEASE don’t superglue your dentures unless you are absolutely desperate, you can confidently get it back together accurately and it’s a temporary solution.

    Superglue will expand and bubble over time ruining the denture acrylic. The denture will no longer fit and you’ll have to go back to your dentist to have an impression made, hopefully then the lab can repair from this.

    If you can find a local dental laboratory they should offer a same day denture repair service (and you shouldn’t have to go through your dentist).

    You shouldn’t need a new denture just because it’s broken; unless it’s completely obliterated (and I repaired one in 12 pieces once that a pet dog had gotten hold of), it should be fine to repair. Same goes for teeth that pop off the plate.

    Also! – don’t put them in strong denture cleaning tablet solutions; they’ll leach the pink colour right out and pop the teeth off. There’s a reason you can clean a toilet with them!
