What are dental crowns?
A dental crown is used to entirely cover a damaged tooth. It can improve the way a decayed or broken tooth looks and make it stronger and longer lasting.
What happens during a dental crown procedure?
The dentist will usually prepare the tooth by removing a layer of its outer surface. The crown will be the same thickness as the thickness of this removed layer. To make a crown, the dentist takes a mould of the tooth and sends it away to a technician who will prepare the crown. It can often be matched to the colour of the other teeth, so it will blend in. You might be given a temporary crown to get you through until the permanent crown is made. When the permanent crown is ready, the dentist fits it in place using dental cement or adhesive.

Your dentist may recommend a crown to:

• Replace a large filling when there is not enough tooth remaining.
• Protect a weak tooth from fracturing.
• Restore a fractured tooth.
• Attach a bridge.
• Cover a dental implant.
• Cover a discoloured or poorly shaped tooth.
• Cover a tooth that has had root canal treatment.

How long do crowns last?
Although today’s dental crowns are strong and durable, they will last between 5 and 15 years before needing to be replaced or at least repaired and this is also dependant on how well your oral hygiene is. If you are flossing every day and brushing your teeth and gums the better the outcome.
