A crown is a cap that covers the tooth in order to either strengthen a fragile tooth, or improve the appearance of a tooth. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. Crowns are shade-selected to match your surrounding teeth so they appear like your natural tooth.
How is it done?
There are two appointments required for a crown.
At the first visit, the tooth is reduced down in size by approximately 1mm from around the circumference and 1-2mm from the biting surface of the tooth. An impression is taken of the tooth and is sent to our dental laboratory for the construction of the crown. A temporary, tooth-coloured crown is placed while we wait the one-two weeks before the next appointment.
At the second visit, the dentist removes the temporary crown and tries in the permanent crown. If the colour and fit are correct, the crown is cemented permanently.
There is a small risk that the nerve inside the tooth may die, as is the case when a tooth sustains any type of disturbance. If nerve death does occur, a Root Canal Filling would need to be performed.
If the crown ever dislodges, it means the cement has broken down. We then simply re-cement the crown.
There is a future risk that either the root or the core of the tooth may fracture. Different options are available depending on the depth of the fracture and condition of remaining root.
A conservative estimate is 10 years. The life of any dental restoration is lengthened with diligent home care maintenance.
Conscientious home care including brushing every morning and night, flossing once a day and regular six monthly check-ups to review the crown and surrounding teeth.
