What is a dental crown?

A crown, also known as a cap, is placed over the top of the natural tooth to make it stronger. It is often used in cases where teeth have been weakened or damaged due to decay, injury or trauma.

Why would I need a crown?

You may need a dental cap if your tooth is decayed or weak due to an accident, injury or a large filling. A crown may also be placed after root canal or dental implant treatment.

What materials are used?

The most common material used is porcelain fused to metal, but crowns can also be made entirely from ceramic materials or precious metals. Porcelain is popular because it is the same colour as natural teeth, while metal fixtures are hard-wearing and often recommended for molar teeth.

What happens during the treatment?

The tooth is initially prepared by removing any decayed or damaged tissue and cleaning the area thoroughly. Your dentist will then take an impression of your tooth and use this for the fabrication of your new crown. The entire treatment involves two appointments and you will be advised when to schedule your appointments.

Will the crown be noticeable or feel any different?

If you have chosen ceramic or porcelain this should blend in without any problems. Metal crowns are more visible but generally used on the back teeth. The tooth may take a little getting used to, but will soon feel like normal.

How long should a crown last?

Dental crowns can last for several years but you will need to look after them as you would a normal tooth. Dental caps cannot decay, but the surrounding area can, so a good oral hygiene routine must be maintained.

How is a post-crown different?

A post-crown is fitted when a tooth has been root-filled and will hold the cap in place.
