Should I Super Glue a Crown?

Super Glue or Krazy Glue is best used on household items, not your real teeth.

What to do if you lose a crown and you’re nowhere near a dentist? Should you use Super Glue or Krazy Glue to put it back? The quick answer is no. While these permanent glues can be used to suture up wounds in an outback emergency, they are not designed for fixing dental work. Let our Placerville dentists explain why.

Why Not Glue My Crown?

You may think we’re just trying to make more money by asking you to come in to the dental office to fix your crown, but that’s not the point. As we mentioned, these glues are permanent! Crowns are designed to stay on tight, but to be removable in a dental chair. Occasionally, they are dislodged by the patient, but only after many years of use. Fix a crown with permanent glue, however, and now the only way to remove it is by grinding it away or breaking the tooth.

Why might you need to remove a crown? It’s not uncommon for decay to work it’s way up from the roots, not down from the crown. If your crown is essentially unremovable and you face root decay, the pain will be extreme and your dentist will have an extremely difficult time fixing it. It may even lead to the loss of the tooth. Another problem lies with the fit you create when you replace the crown. If you misalign it, a lot of effort will be required to fix it.

How Can I Fix a Broken Crown?

The best fix is to come to the Placerville Dental Group for emergency dentistry. If you’re really out of the way, denture adhesive can help hold the crown in place if you don’t use that side of your mouth for chewing. Carrying a small dental first aid kit, with items purchased from the drugstore for temporary use, can be a useful practice. In a future article we’ll talk about things to include in such a kit.

Are Glues Good For Anything?

One use for Super Glue or Krazy Glue as a first aid dental item is for fixing a broken denture. If you’re away from the dentist and not likely to see one soon, but still want to chew with teeth, you can repair a denture with these glues. Just make sure you practice putting the broken pieces together before applying the adhesive. The denture likely wont fit like it did before and will require at a minimum professional repair and at the worst complete replacement. In either case, come see one of our Placerville dentists as soon as possible. So yes, permanent adhesives are good for something, but it’s not replacing crowns!

    I used nail super glue to place a crown back on. It is tight on my gums but I’m worried about doing it now

      Superglue, or nail glue can work in a pinch.  Realize these glues are temporary and not designed for the oral environment.  Crowns can come off for a few reasons.  One reason is trauma.  The right force can dislodge a crown leaving the tooth underneath unaffected.  If this is the case, we can simply re-cement the crown with FDA approved cement designed to withstand the oral environment.  This is an inexpensive fix.

      Other reasons may not be as simple.  If tooth decay is under the crown, this undermines the foundation for the crown.  If this is the situation, repairing the decay before it spreads is essential to save additional costs and efforts to repair.  

      We often hear the phrase, “It doesn’t bother me…”  Remember, problems are best addressed early before it gets painful.  Whether it be us or some other dental professional, we invite you to get it checked out.

    I have two ceramics one of which in the past four weeks has come off my tooth having attended my dentist on these occasions. What adhesive can I use to permanently secure this ceramic.

      Hello.  It sounds like despite going to your dentist, your crown keeps coming off.  I can’t imagine your dentist using a non-FDA-approved product for cementing ceramic crowns or veneers.  Without seeing it first hand, my initial thought is the preparation does not have enough retention and resistance engineered in the design.  Cement is not the primary way we hold restorations, rather, the restoration itself should fit so well, it stays in without cement. Ideally, cement merely lutes the restoration in place sealing it to prevent bacterial invasion.  Feel free to do an online virtual consult for free where you can submit photos, or schedule a consult.  Thank you!
