If you break a tooth or if you have a restoration like a porcelain veneer, dental inlay, or dental crown come off, you might want to try to glue it back on, especially if you have a special occasion coming up. The only good solution is to contact your dentist and make an appointment to get a professional repair made.

But what if your dentist can’t get you in in time? Well, there are some things you can try to glue your tooth, crown, or veneer back together. None of these are really recommended, but we will evaluate their effectiveness.

Some people may use super glue to fix their teeth.

Denture Adhesives

If you go to forums looking for answers to this question, denture adhesive always comes up, but in general this is not a very good choice. On the plus side, it’s non-toxic and it’s intended for use in your mouth.

The downside is that denture adhesives really aren’t very strong. They’re mostly intended to assist maintaining suction under a denture, which mostly means creating a seal by preventing air from getting in. They don’t have much sticking power.

Denture adhesives might hold a dental crown in place because the situation is similar to a denture, but it might not hold up to chewing. They’re not good for holding veneers or tooth parts in place.

OTC Dental Cement

Dental cement sold over-the-counter as a temporary repair is a better way to hold your loosened restoration or broken tooth in place. But in order for it to work, you have to get the restoration seated properly, which you may or may not be able to do, depending on the type of restoration.

And the hold of the dental cement depends on the amount of surface area where you can apply the cement.

Contact your dentist first and ask if this is okay, but in general this is the best option for temporary tooth repair. It has a decent hold, isn’t difficult to apply, and it’s nontoxic. Remember, though, this is still only a temporary fix: trying to rely on this solution too long can damage your tooth or your restoration. It can also lead to a dangerous infection of your tooth.

Polyurethane Glue

Polyurethane glue is a poor choice for tooth repair. It’s hard to get it to set properly in the moist conditions in your mouth, which means that it can foam up and cause a bad joint between the parts you’re trying to stick together. It’s also highly toxic when it isn’t cured, though it becomes inert once it hardens.


Most of us use the term “superglue” to refer to one of the many brands of cyanoacrylate adhesives, such as Super Glue or Krazy Glue. Some people will say this is a good glue to use to glue your restorations in place, but it’s got a lot of downsides.

These glues stick instantly to your skin, so there’s a risk that you’ll glue your finger to your teeth. Or your cheeks. Or your Lips. Or your tongue. None of which is good.

These also give off toxic fumes. The amounts are small, and won’t cause a serious problem for most people, but for some, the result can be an asthmatic reaction or a significant skin irritation.

Superglues can also have adverse reactions with natural fibers, releasing more toxic fumes or even causing a small fire.

Short Term Repairs at Best

Remember, these are at best only very short term solutions for tooth repair. Attempts to lean on these for long-term care may put you in the situation of a British woman who was afraid of the dentist so she kept using superglue on her teeth and ended up needing dental implants to replace all her teeth.

Don’t let fear keep you relying on home dental repairs. Instead, take advantage of sedation dentistry in Orlando to have a calm demeanor for your dental visit. Please call (407) 834-6446 for an appointment at the office of Dr. Michael L. Weinstock in Altamonte Springs.
