What is A Crown?
A Crown is essentially a jacket made to fit over teeth that have been specifically prepared, to restore the natural shape and appearance of teeth.
Crowns are necessary when:
• A tooth is broken
• A tooth has been weakened after a large filling
• A tooth is discoloured
• A bridge or denture needs holding in place
Are Crowns screwed into the gum?
No. Sometimes crowns may appear to have been screwed into the gum because they fit well into the gumline, but in actual fact, they are simply slotted over the remaining tooth. The remaining tooth will have been prepared for the crown. If the tooth has had root canal treatment, a post may be used by cementing one end into the root canal, the other end will hold the crown in place.
How is a tooth prepared for a Crown?
The dentist will prepare the tooth into an ideal shape for the crown to be placed over. An impression of the prepared tooth will be taken so it can be sent to the laboratory so a dental technician can make the crown. A temporary crown will usually be made to fit over the prepared tooth until the crown can be fitted.
How long does the treatment take?
You will need to have at least two visits, the first for preparation, impression, shade taking and fitting of the temporary crown. The next to fit the permanent crown. There will usually be 10-14 days between appointments.
Always allow enough time if you have up-coming events.
Does it hurt to have a tooth prepared for a crown?
No. A local anaesthetic will be administered and the preparation should feel no different to a filling.
