Types of Dental Glue

If you have never had a broken tooth or never needed to go through a dental restoration, you may not know what dental crown glue is. As a result, if you happen to have experienced a broken tooth, you might want to call your dentist before reaching for any over-the-counter crown glue for teeth.

Sometimes if you have a broken tooth, a dentist may recommend using a dental crown to protect your tooth. A dental crown is a cap that will protect your damaged tooth for a certain period. 

Dentist glue for crowns can be used to put the crown firmly in place. Different types of dental glue can be used for your tooth restorations. We are going to look at what dental crown glue is and the different types available.

What Is Dental Crown Glue?

Dental glue is another name for dental cement. Dentists will use dental glue to secure a dental restoration or a dental implant. These dental restorations may include inlays, onlays, crowns, and fixed bridges.

You can buy over-the-counter dental glue, but it will only be for a temporary solution. These dental glues have chemicals that ensure they achieve their function, which properly secures dental restorations.

Let’s dive briefly into how these dental glues work, and then we can discuss the types of dental glues that are available.

Most dental glues use retention and resistance techniques when you compress them. Crown glue for teeth with a chemical bond is considered stronger than dental cement without a bond. The pressure that is exerted on the crown and the glue is what holds the two firmly together.

These dental glues that are chemically bonded are recommended for severe cases. However, they might pose some difficulty when the crown needs to be removed for dental procedures. In that case, temporary crown glue can be used, and the dentist will recommend using temporary glue because they’ll know you’ll need more work on the tooth shortly.

However, temporary dental crown glue is a good choice, especially for people who continually grind their teeth. These chemically bonded types of temporary dental crown glue may serve such people better than any other glue.

Temporary & Permanent Dental Crown Glue

As mentioned earlier, there are different types of dental glues available. Depending on the longevity of the glue, dental glues are classified into two types: temporary and permanent glue.  

Temporary Dental Glues

This type of dentist glue for crowns is mostly used as a temporary filling kit where it is used to secure crowns and other teeth restorations temporarily. Earlier, we mentioned the type of glue that you can find over the counter; this is the type.

You can use this type of glue for your temporary crowns, which are mostly weak and can easily be removed before you get permanent crowns. Temporary dental glues always include Zinc oxide, eugenol, and olive oil which are all low strength substances.

Some of the features of a temporary dental glue include:

  • They don’t affect the surrounding tissue
  • They are easy to remove
  • It helps to protect the damaged tooth from sensitivity
  • Saliva will dissolve the glue quickly, which is why it needs to be changed 3 to 6 weeks after applying

Permanent Dental Glue

Permanent glue is used to secure teeth restorations permanently. This permanent dental crown glue is made by mixing powder and liquid, making the glue solidify.

Some of the permanent glue features include:

  • The glue is easily tolerated by the tissues surrounding it
  • Provides a strong bond that provides a lasting and permanent solution
  • Unlike the temporary dental glues, the permanent crown glue for teeth does not dissolve in saliva, thus providing permanent protection to the tooth

Types of Crown Glue Based on Composition

Dental crown glue can also be classified depending on its composition. Here are a few:

Glass Ionomer 

The glass ionomer glue is made out of powdered glass, which is mixed with a particular acid. The glue is used to secure both bridges and also crowns that are made from alloy. However, the glass ionomer dental glue never adheres with porcelain. 

The powdered type of this glue is composed of tartaric acid, water, maleic acid, and itaconic acid. The second liquid type, on the other hand, is composed of aluminum oxide, zinc oxide, and calcium.

There are also three types of glass ionomer dental glues. Type one is used on metal tooth restorations and orthodontic brackets. Type two of the glass ionomer is used to repair the tissues near the gingival. Type three of this dental glue is for bonding the dentine.

Zinc Oxide Eugenol 

ZOE also has two versions; the liquid and the powdered version. The liquid version of this cement consists of calcium chloride, water, zinc acetate, and acetic acid. The powdered version is composed of silica, magnesium oxide, and zinc oxide.

Type one, which is weaker in strength, is used in temporary dental cementing. The second type is used in permanent cementing.

Zinc Phosphate

The liquid version of this dental cement consists of water, phosphoric acid, and aluminum phosphate. The powdered version, however, is built with magnesium oxide, zinc oxide, and silica.

It is also available in fine grain and medium grain types. The fine-grain zinc phosphate type is used in permanent cementing, while the medium-grain one is used in the filling of deep cavities.

Composite Resin

The main features of this dental cement are its insolubility in water and a low film thickness which allows for permanent cementing. Composite resin dental glue has various applications, but it is used to cement resin or ceramic teeth restorations permanently.


The liquid version of this glue includes itaconic acid, maleic acid, tartaric acid, polyacrylic acid, and water. The powdered version of polycarboxylate glue contains pure zinc oxide. The main function of this glue is the permanent cementing of stainless steel crowns and orthodontic bands.

Characteristics of an Ideal Dental Cement

The most important qualities of a good dental glue include:

  • Mechanical properties – it should have a high bonding strength.
  • Easy to handle – it should be easy to mix, apply, and clean.
  • It should not dissolve easily – the dental glue should not dissolve in saliva.
  • Good physical attributes – the glue should have low viscosity, short setting time, low solubility, and should also be radiopaque.
  • Biocompatibility – it should always have good biocompatibility with the soft tissues around your teeth.

If you are looking to have your dental restoration secured with dental glue, you need more information. An experienced dentist like the ones at Gables Sedation should explain to you more about these dental cements. It is also important to always get work done by a professional to avoid damaging your teeth further.
