Information about Dental Crowns
WHY HAVE A CROWN?
A Crown is a cover placed over a tooth to rebuild a tooth’s strength, appearance, shape and bite. Crowns are made of All Porcelain, Porcelain with Gold or entirely Gold. Most commonly, crowns are made from All Porcelain. Having a Crown on your tooth is an investment in protecting a tooth’s health for many years. In Cosmetic Cases, Crowns and Veneers allow us to enhance the aesthetic appearance of the teeth by correcting tooth position, shape, surface texture, and colour.
WHAT IS INVOLVED?
In the first step, the Tooth is prepared for the Crown. This involves: Local Anaesthetic, Drilling, Removing Decay, Impressions, Shade Taking, and a Temporary Crown. You will then wear the Temporary Crown for a period of 2-3 weeks. During this time you need to be careful to clean appropriately, and alter your diet to avoid chewy, sticky foods.
At the second step, the temporary crown is replaced with the final crown. This involves: Local Anaesthetic, Removing the Temporary Crown, Cleaning, Fitting the New Crown and Bonding it in place and Reviewing.
WHAT ARE THE RISKS?
Crown Treatment does have risks, that can be minimised through appropriate planning and treatment programs.
Tooth Risks: In approximately 5% of teeth which have been recently crowned, the Nerve may die and require Root Canal Treatment. This is usually a result of either waiting too long before the crown was done, or as a result of cracks that have been in the tooth for many years. In some cases, the Root Canal Treatment can be performed through the biting surface of the crown, whilst in others the Crown will need to be taken off to get to the Root Canals.
Prosthetic Risks: Cosmetic, Porcelain Fracture. Some of these Risks can be easily dealt with by removing and reinstating the Crown, whilst others may require a new crown to be constructed. Your Crown is guaranteed for a period of five years for defects in construction.
HOW DO I PREPARE FOR A CROWN?
It is important to follow the pre-appointment instructions and prepare for after your appointments.
Take any prescribed medications strictly as directed. Have a good meal before your appointment as your mouth may be numb for a number of hours afterwards.
Be prepared to follow special dietary requirements including reducing the amount of chewing, watching your fluid intake and taking supplements, and special cleaning techniques.
