Dental Crown & What It Is.

A dental crown is a tooth-shaped “cap” that is placed over a tooth to cover the tooth to restore its shape, size, strength as well as improve its appearance. When cemented into place, the crowns fully encase the entire visible portion of a tooth that lies at and above the gum line.

How Long Do They Last?

On average, dental crowns last between five and 15 years. The longevity of the crown depends on the amount of wear and tear the crown is exposed to, how well you adhere to good oral hygiene practices as well as your mouth-related habits like chewing ice, grinding or clenching your teeth, biting fingernails, etc.

Dental Crown: Why You Need One!

Dental crown restorations are one of the most common dental procedures dentists perform. Occasionally, people have crowns placed to fix all kinds of tooth and mouth problems, and that is what we at Rathgar Dental do best!

While most people tend to be frightened by the idea of having a crown restoration, there is nothing to be afraid about. A crown restoration is vitally important, but there’s no need to be scared about the procedure, as it is logical and straight-forward. More importantly, dental crowns perform essential functions for tooth and mouth health.

The following situations necessitate having a dental crown:

  • To protect a weak tooth from breaking, for example, due to decay or to hold parts of a cracked tooth.
  • To restore an already broken tooth or a tooth that has been severely worn down.
  • To cover and support with a large filling when there isn't a lot of teeth left.
  • To firmly reinforce a dental bridge in place.
  • To cover a dental implant.
  • To cover misshaped or severely discoloured teeth.
  • To make a cosmetic modification.

Moreover, dental crowns can also be used on primary or baby teeth to:

  • Save a tooth that has been severely damaged by decay that it can’t support a filling.
  • Protect the teeth of a child at high risk for tooth decay, especially when a child has difficulty in keeping up with daily oral hygiene.
  • Decrease the frequency of general anaesthesia for children because of age, behaviour, or medical history, which makes them unable to fully cooperate with the requirements of dental care.

Under such circumstances, a pediatric dentist is likely to recommend a stainless steel crown as it is commonly used to fit over a primary tooth that’s been prepared to fit it. The crown will cover the entire tooth and protect it from decay.

Be sure to give us a call or visit when you need a dental crown for any of the above dental conditions as we are always ready to help you!

What Types of Dental Crowns Are Available?

Permanent crowns can be made from stainless steel, porcelain-fused-to-metal, all metal (such as gold or another alloy), all resin, or all ceramic.

Stainless steel

Stainless steel crowns are prefabricated crowns that are used on permanent teeth primarily as a temporary measure. The crown helps to protect the tooth or filling, whereas a permanent crown is made from another material. Stainless steel crowns are commonly used for children’s teeth.


Porcelain-fused-to-metal dental crowns can be colour-matched to your adjacent teeth, unlike the metallic crowns. The drawback, however, is that more earing to the opposing teeth occurs with this crown type as compared with metal or resin crowns, and the crown's porcelain portion can also chip or break off.

All-ceramic or all-porcelain

​All-ceramic or all-porcelain dental crowns are known to provide better natural colour match than any other crown type and may be suitable for people with metal allergies. All-ceramic crowns can be used for both front and back teeth.


Metals used in crowns comprise of alloys that have a high content of gold or platinum, or base-metal alloys. Examples include cobalt-chromium and nickel-chromium alloys. Metals crowns are known to withstand biting and chewing forces well and tend to last the longest in terms of wear down as they rarely chip or break.


All-resin dental crowns are cheaper than the other crown types even though they tend to wear down over time and are more prone to fractures than porcelain-fused-to-metal crowns.

Steps Involved in Preparing a Tooth for a Crown

Preparation of your tooth for a crown usually involves two visits to the dentist. The first visit involves examining and preparing the tooth while the second visit involves placement of the permanent crown.


First Visit: Examination & Crown Preparation.

At the first visit in crown preparation, your dentist will check the roots of the tooth receiving the crown and surrounding bone with the help of X-rays. If the tooth has extensive decay or if there is a risk of infection or injury to the tooth’s pulp, a root canal treatment may first be performed.

Before the crown-making process begins, your dentist will then anaesthetize or numb the tooth and gum tissue around the tooth. Next, the tooth receiving the crown is filed down along the chewing surface and sides to make room for the crown. If a large area of the tooth is missing, "building up" the tooth with the help of filling material is done to help the tooth support the crown.

After reshaping the tooth, paste or putty is used to make an impression of the tooth receiving the crown. A digital scanner can also be used to make the impressions after which the impressions are sent to a dental lab where the crown will be made. Within two to three weeks, the crown is usually ready for fitting.
During the first visit, a temporary crown made of acrylic is made to cover and protect the prepared tooth whilst the crown is being made. The temporary crowns are usually held in position using temporary cement.


Second Visit: Receiving the Crown.

At the second visit, there is less to be done, as your dentist will remove the temporary crown and check the fit and colour of the permanent crown after which the new crown is permanently cemented in place with the help of a local anaesthetic, provided everything is perfect.

How Much Do Crowns Cost?

Crowns cost vary geographically and on the type of crown selected. For instance, porcelain crowns are typically more expensive than gold crowns which are also more costly than porcelain-fused-to-metal-crowns. 

Generally, crowns can range in cost from 563 to 1,200 Irish Pounds or more per crown. You can checAk with your dental insurance provider to ascertain if it covers costs of crowns replacement.
