How to Make a Dental First Aid Kit

An Oral Answers reader, Rebecca recently asked the following question:

“In the wake of the earthquake in Japan, my friends and I have been checking/building our disaster kits. One thing that’s come up has been what should be packed in a dental first aid kit. None of our first aid kits contain dental first aid items so we thought we’d build our own. What would you suggest that we add for a family of four? We’re assuming that a toothbrush, toothpaste and floss is only the beginning.”

Dental First Aid KitRebecca brings up a good point about the importance of being prepared for dental emergencies when they occur.  We never know when one of our children might lose a tooth in an accident.

If you’re interested in making your own dental first aid kit, there are many items that you may choose to include, depending on your level of dental experience.  Also, you need to know if you want to pack regular oral hygiene items (such as toothpaste and floss) in with your main disaster kit, or if you want to include it in your dental first aid kit.

For the purposes of this article, I will simply go into the things that you may want to have on hand in case a dental emergency occurs and you are unable to make it to the dentist for whatever reason.

What to Put in a Dental First Aid Kit: A List of 14 Possible Dental First Aid Kit Items

You can use the list below to find some things that you may want to include in a dental first aid kit, broken up into a few categories.

Help with Examining the Dental Emergency

1 – Medical-Grade Exam Gloves – Even if you’re comfortable reaching into your child’s mouth without gloves, it may be a good idea to wear gloves anyway due to the germs that you have on your hands.

2 – Dental Mirror & Flashlight – If a piece of tooth chipped off, or if someone has lost a tooth, it’s a good idea to look inside of the mouth and see if there is anything remaining at the site of the accident.  A mirror can also help you visualize the tongue-side of the front teeth.

Saving a Knocked Out or Lost Tooth

Save a Tooth System

3 – Save-a-Tooth System – The Save-A-Tooth System is simply a saline solution that is compatible with our bodily fluids.  It is the best way to keep a tooth “alive” when it is knocked out and not immediately re-implanted.  It is important to remember that a tooth can only be outside of its socket for a few hours before the probability of successful re-implantion starts to go down-hill fast!


In short, you only need to get this if you’ll be able to make it to the dentist within a few hours of having a tooth accidentally knocked out so that the dentist can re-implant the tooth.

Helping with a Lost Crown, Lost Filling, or Chipped Tooth

4- Temporary Crown and Filling Material – These materials, which I talked about in a previous post about the best temporary crown cement can help you get by until you can see a dentist.  Note that it is always best to see a dentist first when a crown or filling falls out.

To learn more on this topic, read about what to do when a filling comes out and what to do when a crown falls off.

5 – Dental Wax – Wax can be used to help with irritation from braces or a chipped tooth.  Some people have also used it to temporarily fill in a lost filling.  Dental wax can be found for pretty cheap on Amazon.

6 – Toothbrush & Tweezers – When putting a loose crown back on and replacing a lost filling, it is important to make sure that the tooth is clean by using a toothbrush.  You’ll also need a good way to handle the filling material, which is where the tweezers come in.

Controlling Bleeding

7 – Sterile Gauze – Gauze placed over the site of bleeding can help stop bleeding. You can also use gauze to move the tongue (it’s usually pretty slippery with gloves on!) so that you can see what’s going on inside the mouth.

8 – Tea Bag – If bleeding hasn’t stopped with just gauze, it can sometimes help to place a wet tea bag inside of a piece of gauze and hold that over the wound to stop bleeding.

9 – Hydrogen Peroxide – If you need to disinfect and clean up blood, hydrogen peroxide good to have around in your dental first aid kit.

Alleviating Dental Pain

10 – Floss, Toothpicks – Sometimes tooth pain is simply caused by food that is stuck between teeth that can easily be removed with floss and/or toothpicks.

11 – Clove Oil – Clove oil (or eugenol in dental-speak) has a sedative effect on the dental pulp and can be used to help alleviate tooth pain.  Many dentists use eugenol in their offices to help calm down teeth after deep fillings.  This is why clove oil is commonly associated with the dental office smell.

If you’re looking for a quick way to get some clove oil into your dental first aid kit, it can be found along with sesame oil in these Red Cross Toothache Medication Drops over at Amazon.

12 – Ice Pack – An ice pack can help reduce swelling when a tooth is lost.  At my dental school, whenever we extract a tooth, we recommend that the patient place an ice pack on their face intermittently (20 minutes on, then 20 minutes off) to reduce swelling.

13 – Orajel or Anbesol – Sometimes Orajel or Anbesol can do a better job at relieving oral pain than clove oil.  When giving an oral anesthetic to your children, it’s important to be aware of methemoglobinemia, a serious side effect.

14 – Pain Medication – Over the counter pain medication, such as ibuprofen and acetaminophen can help relieve oral pain, but should only be taken as directed.

Where to Buy a Dental First Aid Kit

Some people don’t want to go through the hassle of making their own dental first aid kit and prefer a ready-made solution.  There are a variety of different dental first aid kits available for sale online.  Here are two from Amazon that grabbed some good customer reviews:

Dental First Aid Kit - Dental MedicDental Medic Dental First Aid Kit (Pictured to the left) – This kit includes dental wax, floss, a tea bag, and an oral pain reliever among other items.  It also has an instruction booklet for dealing with common dental emergencies and comes in a waterproof bag.

Emergency Dental Kit (Pictured below) – This dental first aid kit appears to include a few more things compared to the dental first aid kit above.  It includes a mirror and appears to also have a Dental First Aid Kit Emergency Kitcontainer of clove oil included.

If you’re looking for some other options, this Google Shopping results page and this page at Amazon both show many other dental first aid kits that are available.


Dental first aid kits can be valuable assets when it comes to your oral health and your children’s oral health.  Nobody knows when an emergency will occur, so it is always a good idea to be prepared to handle dental emergencies.

Why Crown Fell Off
©Alex Mit/

Have you ever bit into a sticky piece of candy only to find out that the candy grabbed the crown that your dentist just put on your tooth?

Gold Crown Fell OffIf so, you’re not alone!  Many people lose crowns from their teeth.  A crown that fell off is a common “emergency” that we see at the dental school.

You may be curious why your crown fell off.  To satisfy your curiosity, I’ve written this article to let you know about some of the reasons that crowns fall off teeth.

Six Reasons Why Your Crown Fell Off

1 – The tooth underneath the crown got decayed. Many people think that when they get a crown, their tooth is bulletproof.  Crowned teeth can get cavities!  The cavities usually occur right at the junction of the crown and the tooth along the gum-line.  In this case, your dentist will evaluate the tooth to see if it is able to hold a new crownyou will most likely need a new crown made

2 – The cement holding the crown on wasn’t strong enough. This could be due to contamination of the cement while it was being prepared or any number of other reasons.  If this is the case, your dentist can usually re-cement the crown back ont your tooth.

3 – You ate too many chewy foods. As you can see in the picture above, one jelly belly was all it took for Bev Sykes’ crown to fall off of her tooth!  Over time, sticky foods can gradually work a crown loose.  When the crown is pulled off by sticky food, it can usually be re-cemented onto the tooth.

4 – The crown broke. In some instances, due to lots of force, the crown can break and fall off the tooth.  Sometimes a crown can gradually form a crack that eventually loosens the crown’s seal with the tooth and knocks it loose.

5 – You abused your crown. Maybe you used your teeth as tools, or you ended up putting unnatural stresses on the crown by grinding your teeth.   In any case, when you subject your crown to unnatural forces, you stress the bond that holds the crown to the tooth.

6 – There wasn’t enough tooth structure to hold onto the crown. Sometimes the teeth are so short that when dentists prepare them for a crown, there’s not much tooth left for the crown to “grab on to” when it is finally in place.  This is more common in back teeth that have been worn down over years of use and are short.


There they are!  If your crown fell off, it was most likely due to one of the reasons mentioned above.  It is always best to go see your dentist when a crown falls off.  If you can’t make it to your dentist in a timely manner, they may recommend that you pick up some temporary crown cement from your local pharmacy to hold the crown on until you can be seen at the dental office.

Do you have any questions about crowns and why they fall off?  I’d love to hear any questions or comments you may have in the comments section below.  Thanks for reading!

Best Temporary Crown Cement and Way to Recement Crowns

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.

Temporary Crown Cements

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 Temporary Crown CementRecapit 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 CementTemparin 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 One Step Temporary Crown CementDentemp 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!


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.


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.

Crown Fell off Tooth

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.

What to do When Your Dental Crown Falls OffCrown 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.

Recapit Dental Crown Cement

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.


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!
