Dental Crowns: What You Should Know

by | Apr 14, 2023 | Dental Crowns, Dental Infographic


A dental crown is a teeth-shaped “cap” that is put over a tooth – to cover the tooth to restore its shape and size, and strength and improve its appearance.

What is the purpose of a dental crown?

Some of the situations crowns are called for include:

  • Rehabilitating damaged teeth so they look attractive and work naturally
  • Replacing a damaged or missing filling
  • Protecting a decayed tooth
  • As an anchor for dental bridges
  • As the cap over a dental implant creates a naturally functioning tooth
  • Covering a tooth that has undergone root canal therapy.

Dental crowns are similar to your natural teeth. Your Cardiff dentist can create them to match the size, feel, and shape of your existing teeth – so they fit into your bite, and you don’t have to worry when you bite or chew.

Crowns are flexible. The colour, shape, and general appearance of a crown can be altered so that a crown can give you back your beautiful smile. Because crowns can be used in many dental situations, they can help you avoid other, more expensive dental procedures.

In some cases, crowns can cover particularly large cavities that might otherwise require a root canal procedure.

Types of dental crowns

Crowns can be made from many different types of materials, including:

  • ceramic
  • metal
  • a combination of materials
  • stainless steel
  • porcelain
  • zirconia

Instead of an all-porcelain crown, you might choose porcelain bonded to metal.

Your dentist will take the following into account when choosing the material for your crown:

  • position of your gum tissue
  • colour of the surrounding teeth
  • how many natural teeth are still present
  • use of the tooth that requires a crown
  • your tooth’s location
  • how much of your teeth will be visible when you smile

You can also discuss your preferences with your dentist.

Who needs a crown?

You might require a crown if you have a huge cavity too large for a filling.

A crown may also be required if your tooth is:

  • cracked
  • weakened
  • severely worn down

Additionally, crowns are advised since the tooth is more vulnerable and needs protection after a root canal.

If the dentist needs to install a dental bridge or a tooth implant because you are missing a tooth, you might be a candidate for a crown.

How long do dental crowns last?

Longevity! The normal lifespan of a crown is up to a decade, and they can last even longer. Check your dental insurance because many plans include crown replacement if needed after five years.

Longevity means that crowns are permanently placed. They do not budge. Other appliances can crack, drop out, or be lost, but crowns stay there!

Crowns can also cover weak teeth and eliminate the need for their extraction. A crown can restore a tooth’s original strength and function.
