A crown is a type of dental restoration used to fix teeth that have been broken, weakened by decay or contain a very large filling. Here is how it works:
- An impression is taken of the tooth that needs restoring.
- A crown is made in the dental laboratory to fit the tooth precisely and match the neighbouring teeth.
- The tooth is then prepared and the crown fitted securely on top.
A crown could be a good solution for you if you have some discoloured fillings and would like to improve their appearance. Crowns can be used to replace these to give you a more appealing smile. Additionally, if you have had root canal treatment you will need a crown to protect or cap the restored tooth, allowing you to eat and bite down on it as if it was a real tooth. Crowns are also used to anchor a bridge or denture firmly in place in the mouth.
In today's world, few of us have the time to visit the dentist for multiple appointments in order to receive dental treatment. At the same time, sitting for hours in a dental chair is not ideal either. One solution to this is called CEREC, a state-of-the-art machine that can make permanent crowns, veneers or onlays for you while you are still in the chair. Here is how it works:
- The dentist will prepare your tooth using a small drill.
- A special camera is then used to take an image of your teeth which is then uploaded to the design unit.
- This image is uploaded to a CAD/CAM unit, which creates a 3D model of your new tooth.
- The model is used by a milling machine, which creates your new tooth from a block of high quality ceramic that best matches your surrounding teeth.
- The restoration is then fixed into place.
- Accurate restoration that strengthens and supports the remaining tooth structure.
- Quick and convenient solution that means you don't need an extra visit to the practice, have to wear a temporary fitting for a few weeks or get anaesthesia twice!
- A natural-looking restoration that blends in well with your surrounding teeth.
