Dental Crowns

Our dental crowns or ‘caps’ are ideal for improving the appearance of your teeth, helping you to have a smile you feel great about.

A Crown, or porcelain crown, is a cap, cover or restoration to replace the missing portion of a tooth.

There are many reasons for crowning teeth. These can be due to aesthetic considerations but most are due to a lack of remaining tooth structure. Crowns are an ideal way to rebuild teeth which have been broken, or have been weakened by decay or a very large filling. The crown fits right over the remaining part of the tooth, making it strong and giving it the shape and contour of a natural tooth.

What types of dental crown are there?

Crowns are created from a selection of different materials. There are currently three popular choices for crowns; we have detailed them below:

Porcelain bonded to precious metal

This is what most crowns are made from. A precious metal base is made and then porcelain is applied in layers over it.

All-ceramic

This modern technique offers a metal-free alternative, which can give the strength of a bonded crown and the appearance of a porcelain crown. Therefore it is suitable for use in all areas of the mouth.

Gold-alloy crowns

Gold is one of the oldest filling materials. Today it is used with other metal alloys to increase its strength, which makes it very hardwearing.

Frequently Asked Questions

Dental crowns, often known as a ‘cap’ are an artificial restoration that comfortably fit over the remaining part of a tooth, to make it robust and give it the shape of a natural tooth.

Crowns are a great way to repair teeth that have broken, have a large filling or have become weakened by decay.

Dental crowns are an ideal solution for restoring the shape, strength and appearance of a damaged tooth. Crowns are fitted to protect the most vulnerable part of the tooth by shielding it from potential damage. Therefore, after you have one fitted, you can safely use your tooth to chew without the risk of damaging what is underneath. A crown will fit tidily on the tooth in an identical way to a sewing thimbles fitting onto the fingertip – carefully over the top of a tooth.

Dental crowns are excellent at restoring the structural integrity of your mouth and bite. Unfortunately, when a tooth decays or breaks, it leaves an unwanted gap. This gap can eventually lead to more problems as it can easily interfere with your bite. By filling that gap with a crown constructed of resilient materials, your mouth’s proper structure will be restored to a healthy state.

1) The dentist begins by preparing the tooth for the procedure; this starts with removing the tooth’s outer portion to ensure the crown will fit correctly. Any decay is also removed. Your dentist may then build up the core of the tooth if additional tooth structure is needed to support the crown.

2) Next, an impression will be made from a mold or a digital scan of the tooth is created to provide an exact model for the crown.

3) It is possible that you will be fitted with a temporary crown while you are waiting for your new permanent crown to be crafted. This process will usually take less than two weeks. Throughout the time you have a temporary crown, you may find the tooth to be sensitive to hot and cold. It is advisable to avoid eating sticky foods during this period.

4) Once your new crown is ready, your dentist will place it in your mouth and then make any required adjustments. It is only once both you and your dentist are happy with how it looks and feels, will the crown be cemented into place.

You may need a dental crown for several reasons, including:

  • To restore a chipped, cracked or broken tooth.
  • To cover and protect a tooth that’s been treated with a root canal or filling.
  • Protecting a weak tooth (possibly from decay), and too much is missing for a filling.
  • To hold a dental bridge in place.
  • To cover a dental implant.
  • To prevent further damage to teeth affected by tooth decay and other issues.
  • To cover misshapen or severely discoloured teeth.
  • To improve the cosmetic appearance of teeth.
The lifespan of a dental crown depends on several factors, such as the quality of the crown, the oral hygiene habits of the patient, and the location of the crown. On average, dental crowns can last between 10-15 years with proper care.
