Crowns

What are Crowns?

Crowns, also known as ‘caps’ become necessary when a tooth is broken down from previous decay or following a break. A crown fits over the remaining tooth and restores its natural shape.  Crowns cover most of the visible tooth, whereas ‘Inlays’ and ‘Onlays’ just replace the parts of the tooth that are missing.  Crowns, Inlay and Onlays all have their place when fixing broken teeth.  Your Dentist will discuss the options with you and advise you on which is the most appropriate and the best for your tooth.

What’s involved?

Traditionally crowns have taken two separate appointments - during the first appointment the tooth is shaped or ‘prepared’ to take the crown. A digital scan (hyperlink to Digital Dentistry page) is then taken from which the crown is made. A temporary crown is then fitted and two weeks later, a second appointment is required to fit the crown.  Because the area is numbed before the process is started, the treatment is perfectly comfortable.

What are they made of?

These crowns can be purely porcelain (tooth coloured), metal, or porcelain fused to metal. Crowns can look incredibly natural - it’s often difficult to tell a crowned tooth apart from a natural tooth. We use state of the art materials such as Emax and Zirconia. We will discuss which material is best for your tooth and listen to your personal preferences.

Cases 1

Crown and White Fillings

This patient came to us with existing metal fillings and a chipped back tooth.

The patient wanted to improve the appearance and so we replaced the metal fillings with new white fillings and placed an Emax crown on the broken tooth.

The treatment was completed over two visits and the end result looked very natural

Cases 2

Crowns and Onlays for Back Teeth

This patient came to use with broken back teeth.  The teeth kept chipping and breaking and he was getting tired of having the teeth ‘patched up’.  We decided to use a combination of Crowns and Onlays to fix the broken teeth.

The end result looked and felt really natural.  The blue sheet over the teeth is called a ‘rubber dam’. We put this over the teeth during treatment to keep the teeth clean and dry, and to make the process more comfortable for you.

Post-Retained Crown for Front tooth

This patient came to us with a badly broken front tooth.  He didn’t think that we would be able to fix it as it was broken off at the gum.

We were able to put a ‘pin’ or ‘post’ into the root of the tooth to support a new crown.  This is therefore called a ‘Post-Retained Crown’.

The end result looked just like the old tooth.  We used photos of the teeth from before the accident to make sure the end result looked totally natural.
