Denture glue.

Dental glues, or cements, are specific materials used in dentistry to attach crowns to the abutment or to attach brackets to the surface of the teeth. Dental glues are made of different components; the most common are glass ionomer (GI) and resin-modified glass ionomer (RMGI), but there are also zinc oxide-eugenol, zinc phosphate, resin cements or self-adhesive resin cements that contain silicate.

Depending on several factors, the dentist decides which glue is the most suitable.

A dental glue can work by creating resistance and retention when compressed, or it can form a chemical bond; some glues are activated with ultraviolet light.

Glues that form a chemical bond are stronger than the others so that they can be chosen for patients with grinding teeth, but they are more difficult to remove in case a crown needs to be replaced or repaired.

Dental glue for teeth. The use.

Dental glues can be used for temporary or for permanent works; zinc oxide-eugenol glue is usually used to attach a temporary crown. Today, it is also possible to buy an over-the-counter temporary glue, to attach a crown fell off. This solution can’t substitute the work of the dentist; the patient has to visit a dentist as soon as possible.

According to doctors, the crown has a non-porous surface and can be moistened, while the tooth is very porous, so the adhesion between the two can not last if a dental glue is not suitable.

Anyway, a permanent dental glue can work for years, depending on its proper application and the ability of the patient to follow a good oral hygiene.

Every type of treatments requires its suitable cement. GI is most preferred with stainless steel and metals, but not with porcelain, and it is soluble in oral fluids. On the contrary, RMGI is completely insoluble, but it doesn’t work with ceramic crowns.

All-ceramic crowns are usually attached with resin glues.

The dentist decides which is the right type of dental glue to use according to the tooth being cemented, the kind of dental procedure being done, and how long the glue is needed. Mainly referring to dental crowns, their longevity doesn’t depend only on the glue. A proper oral hygiene and regular check-ups are necessary to prevent damages or to avoid bacteria from entering the crown and cause cavities.
