It is easy to assume that you are never going to encounter a real dental emergency that requires dental glue. After all, you are doing everything that you can to take good care of your teeth—cleaning them twice a day, being careful of what you bite into, flossing regularly and visiting a dentist every now and then.

However, if you have ever experienced a broken tooth and required dental restoration, it may have been tempting to simply glue the tooth back together with your everyday craft glue. This is definitely not something you should do!

There is actually a kind of glue for teeth, which goes by the name of dental glue, and is used by dentists to help restore broken teeth and prevent further damage.

So what is dental glue? What is it made of and how does it help with a dental repair? Keep reading to find out!

If you are wondering how to temporarily repair your tooth at home, our guide to home tooth repair kits can help.

What is dental glue?

Dental glue, also known as dental cement, tooth glue, or tooth crown glue, is an agent that a dentist uses for securing a dental implant or restoration, for example, a fixed bridge, inlay, onlay, or crowns, to your damaged teeth. It co be purchased over the counter, but in this case, it is only meant for very temporary treatment.

Dental cements possess unique chemical features that aid in achieving their purpose: to ensure that the carefully crafted dental restorations stay exactly where they should be—in your mouth.

Dental glue is usually advertised as a short-term fix for chipped teeth, damaged veneers, and broken crowns. However, some newer products have been launched which can be used as a long-term solution as well.

Let's take a brief look at how dental glue actually works.

How does dental glue work?

Dental glue uses retention and resistance upon compression to work. In some types of dental cements, a formation of chemical bonds also occurs.

The force exerted by the compressed dental glue lying just beneath the crown of the tooth is what holds and bonds it together. The chemical bond formed between the glue and the crown provides extra strength and it is less likely to break down as compared to glue that does not form bonds.

However, because chemically-bonded dental cement possesses higher strength, it may cause difficulties during the removal of crowns for repair or replacement purposes.

Stronger dental cement is a great option for those who continually grind their teeth as it can provide additional stability to the crowns and keep them intact for a longer duration of time.

Types of dental glue: permanent vs temporary

Dental cement has been classified into three different types based on their application uses.

Type of cement Application
Type I(a) Fine grains used for luting and cementation
Type I(b) Medium grain used for orthodontic purposes
Type II Used for restorative purposes
Type III Used for liners or base applications

Dental glue for crowns and other restorations are classified differently based on their duration of use and composition.

There are two types of dental glue depending on the length of time for which they are used:

  • Temporary dental glue
  • Permanent dental glue

Temporary dental glue

Temporary cement is a part of the temporary filling kit which is commonly used to fix crowns and other restorations for a short duration of time. A dentist uses this kind of dental crown glue in circumstances where they wish to observe and assess the response of your teeth to the restoration in use.

Temporary cements are usually made up of eugenol, olive oil, and zinc oxide powder.

Temporary dental glue features the following aspects:

  • It provides a good grip on teeth as well as on the dental crowns
  • It is easily tolerated by the surrounding tissue
  • It is easy to remove
  • It protects a damaged tooth and helps minimize its sensitivity
  • Saliva helps it dissolve in a short period of time. Because of this, temporary glue must be replaced with permanent glue in 3 to 6 weeks following its application
  • It possesses a low resistance

Permanent dental glue

Permanent dental glue is the type of teeth glue used for fixing various dental restorations on a permanent basis. In contrast to temporary dental glue, permanent glue is made up of hard and brittle materials obtained by mixing liquid and powder together.

These are the features of a permanent dental glue:

  • It creates a strong bond with the tooth and the restoration to provide long-term, permanent protection
  • It is easily tolerated by the surrounding tissue, thereby preventing dead teeth and tissue.
  • It provides good sealing at the margins to prevent leakage
  • It protects the dental tissue from all sorts of external stimuli
  • It provides exceptional resistance
  • It does not dissolve in saliva or any other oral liquid; offers permanent protection

Types of dental glue: composition

dental cement ingredients
Different ingredients go into each kind of dental cement

Depending on what it's made of, dental cement can be divided into six types:

Glass ionomer cement

Glass ionomer cement is made from powdered glass mixed with an acid. It is used for the final cementation of bridges and crowns made from alloys, but it doesn't adhere to porcelain. Glass ionomer cement is often the material of choice for filling children's milk teeth, too.

Bioceramic cement

Bioceramic dental cement is a permanent adhesive agent that appears opaque on x-rays. It's commonly used for endodontic (root canal) work because it is biocompatible, meaning it can either function as natural tissue or encourage the regeneration of tissue.

Zinc oxide eugenol cement

Zinc oxide cement is an oil-based glue used to soothe the pulp of a broken tooth. It is usually avoided in cases where permanency is required. This cement is particularly helpful to temporarily cement a tooth with exposed dentine. Nowadays, many companies are adding different splinting agents to the zinc oxide cement to grant it permanent luting effects.

Zinc oxide eugenol is not considered to be a strong product for cementing most types of dental restorations, and its use is normally limited to gluing stainless steel crowns, acrylic crowns, and cast restorations.

Zinc phosphate cement

Zinc phosphate cement was one of the first permanent cements to be used in dentistry, and it remains in wide use today for a variety of permanent restoration purposes. Although it doesn't chemically bond to the tooth surface, it has exhibited significant long-term success. However, it is gradually becoming less popular because its relatively high acidity can irritate tooth pulp.

Adhesive resin cement

Adhesive resin cement is a permanent dental glue that bonds with most ceramic and alloy restorations, except implant-supported crowns, veneers, indirect resin restorations, and bridges.

Aesthetic resin cement

Aesthetic resin cement contains translucent resins that are available in different shades, meaning it can be made to match the natural tooth color. It is normally used for bonding all-ceramic and indirect composite restorations, including repairing a chipped tooth. This type of glue has high resistance and utility and a unique composition that does not break apart or dissolve.

How do dentists choose dental glue?

Normally, dentists decide on the kind of dental cement they use depending on the following three factors:        

Longevity

Longevity is one of the main factors that the dentist will consider when choosing the best glue for you. For instance, they may use a temporary or a permanent glue depending on how long you need the crown.

Durability

Durability really matters when it comes to choosing the right kind of dental glue, and it basically depends on the type of restoration used. Permanent dental glue provides good durability and is used for keeping long-term crowns and bridges in place. In contrast, people who do not require a hard finish can try the eugenol-free glue.

Aesthetics

Depending upon your aesthetic requirements, dentists may choose different sorts of dental glue. For example, most people get a temporary glue made with resin because its base is clear in color and it is aesthetically pleasing. At the same time, this type of glue is difficult to remove and may get discolored easily. So, all these factors must be kept in mind when deciding the right type of dental glue.

Dentists carefully select the best type of dental glue for any given procedure.

Techniques for applying glue

There are a number of steps that dentists usually follow in order to apply the glue. In this scenario, we will discuss its application in reference to broken crowns.

  • The mouth is properly cleaned followed by cleaning and disinfection of the crowns. The dentist usually puts a rubber dam or cotton rolls in the mouth to get rid of any fluid.
  • The glue is prepared according to the instructions until the desired consistency is achieved.
  • The dental glue is then applied to the interior of the crown in such a way that it covers it completely.
  • The dentist then places the crown on the abutment of the tooth in order to prevent any misplacement.
  • After the restoration process is completed, all extra glue is cleared away.

After the process, the patient is advised to maintain good oral health and keep in touch with the dentist.

Can you use superglue as dental glue for tooth fixing?

‘Superglue' is the commercial name for cyanoacrylate adhesives meant for a range of household and medical purposes. This type of adhesive is not meant for internal use, so it shouldn't be used as a dental glue. Some people may even have an asthmatic or a skin reaction as soon as they come in contact with superglue.

Superglue may also have a serious reaction with different types of natural fibers, for example, cotton which is commonly used in dental procedures. These reactions exacerbate the release of toxic fumes and may even lead to combustion,

Second, super glue can form instant bonds with your skin. You could easily end up with your restoration glued to your own finger or your finger to your tooth, lips, tongue, or cheeks while trying to fix your broken tooth!

Conclusion

Dental glue is an amazing creation designed to hold your damaged tooth together and protect it from further damage. It can provide both short-term and long-term benefits, but must only be used under the supervision of your dentist. After any procedure involving dental glue to repair your teeth, take extra care regarding your oral health and visit your dentist once or twice a year at least, depending on the recommendation of your dentist, to make sure that everything continues to be in order.

FAQs                             

What glue can you use on teeth?

You should only use dental adhesives when it comes to applying glue to your teeth. Teeth are biological structures that don't respond well to non-biocompatible chemicals. For instance, if you attempt to use superglue, it could end up permanently damaging your tooth, eventually requiring a total tooth extraction.

How can you care for a dental crown placed with temporary dental glue?

When you get a temporary dental crown that is going to stay in your mouth for a couple of weeks, it is crucial to take care of it. This can be accomplished by following the tips mentioned below:

  • Avoid chewing on the side with the affected tooth.
  • Avoid consuming hard-to-chew or sticky foods.
  • Maintain good oral hygiene.
  • Inform your dentist if any discomfort arises.

My crown fixed with temporary glue just fell off. Do I have to go back to the dentist or can I glue it back on myself?

It could happen that the crown placed with temporary glue falls off. In many cases, it may not be possible to see the dentist right away so your best temporary option is to buy an over-the-counter dental glue and fix the crown. This technique may hold the crown in place for a few days until you book an appointment with a dentist.

Remember that fixing your crown on your own is not a permanent solution and you will need to see a dentist ASAP.
