Having a crown come off of your tooth can be very frustrating.  Sometimes you just can’t get into the dentist right away because you’re too busy, you’re on vacation, or your dentist can’t fit you in very quickly.  Some dentists might recommend that you use a temporary crown cement until you can be seen at the dental office.

If your dentist doesn’t suggest a brand name, how do you know which temporary crown cement to use?  There are many different types on the market.  I I decided to provide you with some guidance by reading over the reviews on three of the most popular products for re-cementing your crowns that have fallen off: Recapit, Temparin, and Dentemp.

Below the reviews, you’ll find a few quick tips on how to make your temporary crown cement work.

Recapit Temporary Crown Cement Review

Recapit is available in a multi-use vial or in a stay-fresh tube.

It is a one-step cement, meaning that you don’t have to mix anything together.  All  you have to do is scoop it out and use it to glue your crown back on.

Unlike the other two main temporary cements, Recapit is made only to be used to recement crowns.  Recapit should not be used to replace a lost filling.

The reviews on Amazon range from good to bad.  Many people report that it doesn’t hold their crown on.  One person said that their crown fell off when they sneezed.

Another reviewer who gave Recapit 5 stars said, “I placed the crown back into place and there it stayed for 16 days. Even the dentist was impressed with how well it was holding. I used some sense and tried to keep hard and sticky foods away from this crown. However, I did still chew lightly on it. While I do not expect that you could chew gum or apply heavy pressure to a tooth being help in place with Recapit, it worked perfectly well in my application.”

Temparin Temporary Crown Cement Review

Temparin temporary crown cement is available in a multi-use vial as well.  Just like Recapit, Temparin is a one-step cement which means that you won’t need to mix anything.

On Temparin’s Amazon review page, it only earned 1 5-star review and that was from somebody that used it to replace a filling, not to re-cement a crown.

S. Kennedy, who not only called the Temparin garbage, but worthless garbage had this to say:

“I lost a temporary crown and thought Dentek Temparin might spare me the extra trip to the dentist. Turns out I would have been better off chewing up the five dollars and using that to hold the crown in place. The Temporin lasted no longer than three hours.”

Dentek has come out with an updated formula that they claim is now 10x stronger.  It is pictured in the composite photo at the top of this article and is called Temparin MAX Hold.

Dentemp Temporary Crown Cement Review

Dentemp Temporary Crown Cement comes in a few different versions:

1 – Dentemp One Step (pictured)
2 – Dentemp One Step Maximum Strength
3 – Dentemp Original

Interestingly, the Dentemp One Step seems to have some of the worst reviews while the Dentemp One Step Maxium Strength and Dentemp Original have some of the best reviews.

I noticed that many people complained on the Dentemp One Step reviews that they had changed their formula and what was once a 5-star product is now a 1-star product.  Dentemp Original seems to be the answer to that reviewer, but the one person who reviewed it appears to have been using it to replace a filling, not re-cement a crown.

Dentemp One Step Maximum Strength seems to be Dentemp’s best product when it comes to re-cementing a loose crown.  On the Dentemp One Step Maximum Strength review page, I found the following review by a verified Amazon purchaser:

“I have used this product and was very satisfied with the results. If there is a loose cap that needs to be repaired and a dental appointment is weeks off, don’t fear this product will see you through.”

People also note that Dentemp O.S. Maximum Strength seems to harden very fast, so you may want to try a practice run first to see how fast you need to work to get your crown glued back on.

What’s the Best Way to Re-Cement a Crown When It Falls Off?

The number one piece of advice that I can give you is to follow the directions exactly as written.

Here’s a few other tips that will get your crown to stay glued on tight until you can get in to see your dentist:

• Clean out the crown.  The crown probably has some old glue/cement stuck inside of it.  It is important that the inside be clean and dry so that the new cement can attach to the crown and hold it to your tooth.
• Make sure the tooth is clean and dry.  If you can, blow it dry.  Even a little bit of water can cause the cement to not work well.
• Before cementing it back on your tooth, you might want to make sure that the crown fits evenly on your tooth.  If it doesn’t, there may be some old cement on the tooth or inside of the crown.
• Some people report that if you cement it just before going to bed, it will form a stronger bond as you won’t be using it while you sleep.  This may not work too well if you know that you grind your teeth at night!

Conclusion

Based on the reviews (note that they are unscientific), it appears that Dentemp O.S. Maximum Strength is the best cement for recementing your crown, followed by Recapit and Temparin.

Disclaimer

Remember that before attempting to re-cement your crown you should talk to your dentist to make sure that it is appropriate.  Make sure that you read all package inserts to understand how to use the product, what specific risks are present with use of the product and how to minimize those risks.

If your crown is on a back tooth or upper tooth, know that there is a higher risk of you swallowing or aspirating (breathing in) your crown.  If you have any doubts about whether or not you can get your crown re-cemented, you should talk to your dentist to see what other options are available.

A reader recently asked me if it was possible to get a cavity on a tooth once it has been crowned.  Although it seems logical that a crown covering the tooth would prevent this, that is not the case.  A tooth with a crown can get a cavity!

Can You Get a Cavity on a Tooth With a Crown?

When a dentist makes a crown for you, he or she will remove all of the tooth decay or cavity that was present.  The dentist then cuts around the whole tooth so that a crown can fit over the remaining tooth structure and still appear to be a normal-sized tooth.  The crown/tooth interface is usually right around the gum-line.

That means that you still have tooth structure in your mouth that is below the crown.  If you aren’t brushing and flossing to remove the plaque that lives under the gum-line, you can get another cavity on the same tooth.

What Happens When You Get a Cavity on a Tooth With a Crown?

When you get a cavity on a tooth with a crown, there are a few things that can happen:

1 – If the cavity goes too close to the pulp, you may have to have a root canal done if you haven’t had one yet.
2 – You may need a procedure done known as crown lengthening. Crown lengthening means taking away some of the bone that supports your tooth so that there is room for the dentist to remove all of the cavity and still prepare the tooth for a crown.
3 – You may have to have the tooth pulled if the decay has spread too far into the tooth.
4 – If you keep the tooth, you will most likely need a new crown made.

The procedures listed abovet are all quite costly (aside from pulling the tooth.) Hopefully that will motivate you to keep your crowned teeth clean and in pristine condition!

A few years ago, I was hanging out with one of my friends.  He was biting into a sandwich and his crown came out of his mouth stuck in a piece of bread.  Being a big fan of dentists, I went to the dentist with him that same day and watched as the dentist cemented the crown back into his mouth.

Unfortunately, not everyone can make it to the dentist right after their crown falls off.

Hopefully, if you do end up getting a crown in your life, it won’t fall off.  However, if it does, here’s what you should do.

What to do When a Crown Comes off of Your Tooth

First of all, get the crown out of your mouth.  You don’t want to risk swallowing it or accidentally breathing it in.  If you swallow it, it will probably pass without a problem, but after it’s been through your digestive system you probably don’t want it back in your mouth!  If you end up accidentally breathing it in, it could become infected.

Call your dentist and schedule an appointment.  Let the office staff know that your crown came off.  Give them as much details as you can.  They should try to fit you in as soon as possible (within a few days at most.)

Next, examine the crown and look in your mouth.  If your tooth fractured and is inside the crown, you will have to see your dentist before anything can be done.  If the crown looks hollow or if it is not hollow but there is a small metal rod coming out of it (about the width of a paper clip), then you should be able to temporarily cement it back into your mouth before seeing a dentist to get it permanently cemented.  Before proceeding, check with your dentist to see if it will be alright if you use temporary cement from the drugstore to temporarily put your crown back on.

Take a toothbrush and gently clean off the crown and the tooth inside your mouth where the crown was located.  After cleaning, make sure that the crown and the tooth are as dry as you can get them.

Next,  you will need to have some temporary crown cement which you can purchase at most any pharmacy.  A popular brand name of this cement is Recapit Temporary Crown Cement, which is a temporary glue that will hold your crown onto its underlying tooth structure until you can get in to see a dentist.

Remember to be careful and not chew too hard on the crown that you have re-cemented.  Don’t chew sticky foods like caramel or taffy.  The temporary cement is much weaker than the permanent cement that the dentist initially used.

Update: I have written an article that talks about the different temporary crown cements, which ones have the best reviews, and also gives some tips on the best way to re-cement your crown. You can read it at Which Temporary Crown Cement is the Best?

See Your Dentist To Permanently Cement the Loose Crown

You need to make sure that you go to your dentist so he or she can permanently cement your crown back to its underlying tooth structure.  The crown is still slightly loose, temporary cement really is temporary.

Also, after the crown came off, the underlying tooth structure was exposed to the bacteria in your mouth.  When you cemented the tooth back on, you cemented bacteria between your tooth and the crown.  Your dentist will be able to properly disinfect the area before permanently re-cementing your crown.

Conclusion

If your crown does fall off, remember that you need to get to your dentist as soon as possible.  Don’t put it back on and then neglect going to visit your dentist.  You could infect the tooth and in the worst case scenario you may need to have the tooth extracted a few years down the line.

If your temporary crown comes off, you can re-cement it according to the above procedure.  Your dentist will probably still have you come in for your originally scheduled appointment to have your permanent crown cemented.

Let me know if you have any questions.  Thanks for reading!
