Dental crowns are shaped like teeth and can be used as caps to completely cover original teeth or implants. They are ideal to help protect worn, or damaged teeth and to give extra support to teeth that have been weakened through previous medical treatments or decay.
Many different materials are used in crowns such as, porcelain or ceramic coatings, gold and metal alloys, acrylic or ceramic, composite or a mixture of all the materials. Porcelain and ceramic crowns can be used to give a natural colour appearance to your teeth. Gold and metal alloys are stronger and more suited and recommended for the back teeth. Porcelain bonded to metal can be used as it is strong and gives a better appearance.
For the front teeth, ceramic coatings are a good alternative, supported by zirconium crowns. Zirconium is a similar material to the metals mentioned above; it is solidly built and has a good heat insulating property than can help reduce tooth sensitivity.
When selecting the most suitable material for a patient it is important to take into consideration the image and the function of the teeth, the gum tissue location, and the amount of teeth that appear during the smile. Once all this has been established the best materials can be selected.
