A crown (sometimes called a cap) is a method of restoring the tooth to increase its life, strength, function and aesthetics. If you have a tooth that has been root filled, heavily filled or discoloured, the dentist may recommend a crown for you.
A crown can be made of porcelain, gold, or porcelain fused to gold, depending on the circumstances. Two appointments are generally required.
- Any existing filling in the tooth is removed or reduced at the first appointment.
- During this same appointment, the tooth is reshaped to support the fitting of the crown and an impression is taken of the tooth, in readiness for making the crown. The dentist will also discuss the colour of the crown with you, ensuring that a shade is chosen to closely match your existing teeth and to be most aesthetically pleasing.
- The dentist will fit a temporary crown to protect the tooth and also for aesthetic reasons while the permanent crown is being prepared by the laboratory. Preparation of the crown usually takes about two weeks.
- The crown is made to precisely fit your tooth. During the second appointment, the temporary crown is removed and the permanent crown is fitted. As long as it fits correctly, the crown will be cemented.
- You must care for your crown the same way that you do the rest of your natural teeth, with regular brushing, flossing and maintenance visits.
