Dental Crowns Cost—Material Selection

Crowns (tooth caps) are dental restorations which completely cover the portion of a tooth that sits above the gum line, so they cover that part of the tooth that is visible in the mouth. Dental crowns cost depends on the types of materials that are used to match or enhance someone’s natural teeth. The materials most commonly used for crowns are various types of dental ceramics (porcelains), which provide excellent aesthetics and are particularly used for restoration of front teeth.

Other types of crowns consist of a metal core covered with ceramic veneer. These so-called metal-ceramic crowns provide good aesthetics combined with the strength and durability necessary in areas of high stress concentration, such as the molar teeth. The metallic part is not visible below the porcelain, giving the appearance of a natural tooth. The exclusive use of “noble” gold based alloys ensures value in terms of dental crowns cost.

Occasionally these tooth caps are made completely of gold alloy, predominantly for use on upper back teeth where they provide long lasting service without being visible.

Why Do Teeth Need Dental Crowns

A crown might be recommended for a variety of reasons, typically falling into one of the following categories:

  • To restore a tooth to its original shape.
  • To strengthen a tooth.
  • To improve the cosmetic appearance of a tooth.

Consider dental crowns cost and how that investment long-term can help preserve your natural teeth.

The Steps in Making a Crown

The tooth itself must first be trimmed and sometimes built up to a shape that will allow fitting of a crown. The tooth trimming (preparation) might have to be preceded by complete removal of all existing fillings. This is done to assess the tooth structure and to decide on whether the remaining tooth is sufficiently strong to support the crown. Along the way any underlying decay or cracks would be exposed and remedied, so the crown will ultimately be placed on sound tooth tissue. In some cases, where the tooth is deemed not to be strong enough or insufficient to hold a crown, it will be built up with a new filling that is both strong and well anchored to the tooth to act as a core for the future crown.

Following preparation of the tooth, a silicone impression or mould is taken of the prepared tooth for the dental laboratory. A temporary (provisional) crown is made and cemented onto the prepared tooth until the next appointment. Temporary crowns are strong enough to allow gentle chewing and match the other natural teeth, so that appearance is not compromised and make the most of your dental crowns cost.

The impression taken of the prepared tooth is sent to the dental laboratory where dental technicians will use it to manufacture the final crown to specification

At the next appointment, the temporary crown is removed and the new crown is tried on the prepared tooth. Usually some small adjustments are required at this stage and most of the time they can be done during the same appointment. Once both patient and dentist are satisfied with appearance and fit of the crown it will be cemented onto the tooth with “permanent” cement. If any necessary adjustments cannot be done at this time the temporary crown is replaced on the tooth and the final crown is returned to the laboratory for adjustment, and fitted at a following appointment.

Crown Colour Selection

The colours of teeth are different for everyone. There are also some differences in colours between the teeth of the same person. As a rule, the teeth on the lower jaw are darker than the teeth on the upper jaw; the eye teeth are darker than their neighbours and so on. As well, each tooth is a combination of different colours changing from the neck to the edge. All this makes the exact colour match a very difficult and tricky process and adds to the dental crowns cost. While some simple colours could be matched in the office, in other cases the patient may be asked to visit the dental laboratory to allow the technicians themselves to select the right colour.

How Long Do Crowns Last?

Like most things, crowns do not last forever because they work under very harsh conditions, in a wet environment where they are subjected to constant stress resulting from chewing and clenching of teeth. The dental literature suggests that the average lifespan of a crown is somewhere between 10 and 15 years. This of course varies greatly from one person to another. If a crown is fractured or lost, in many cases a new crown can be made, if the supporting tooth remains in good condition.
