Reasons for fitting a crown

A crown, sometimes known as a cap, is used to artificially restore the strength and natural shape of a tooth. They are most often used to restore broken teeth, or teeth that have been weakened by decay or a large filling. Crowns are also used to improve the appearance of teeth with discoloured fillings, protect teeth that had root canal treatment, or to hold a bridge or denture in place.

Preparing a crown

Crowns can be made from a number of different materials, including porcelain (which can be mixed with precious metal or composite), ceramic, glass and gold alloy.

Your dentist has to prepare the tooth to fit the crown. This involves removing most of the outer surface of the tooth, and then taking a mould of the tooth to be crowned and the tooth opposite. A temporary crown will be fitted until your permanent crown is ready. The dentist will also check your bite, making sure the finished crown fits correctly with your teeth. If you have had root canal treatment, you may require a post crown, which involves inserting a post into the tooth which will help to hold the crown in place. Dental implants can also be used to support crowns.

Fitting a crown

A dental technician will create a crown which matches the shape and colour of your tooth. The crown is normally ready in a week or two. You will then need to come back to have it fitted.

Dental crowns being prepared

The crown is fixed in place with strong dental adhesive, and should last for many years. You may notice a slight difference in the shape of the tooth over the first few days, but you will normally get used to this very quickly. If your crown continues to feel strange or uncomfortable, let us know and your dentist will check it and make any adjustments necessary.
