What is a Crown?
A crown or ‘cap’ is a cover designed to sit over a single tooth’s existing structure. The original tooth is filed down to make room for the crown. Crowns are often needed when a tooth has been weakened by a large cavity or a crack. Dental crowns or bridges fit like a sleeve over your tooth to cover up a fault.
Crowns are most commonly used to make a damaged tooth stronger, and are bonded with extra strong dental cement, similar to fillings. It is permanently fixed for long-term function and serves a variety of purposes, including improving alignment, colour and shape of an existing tooth, and protecting a damaged tooth, or providing strength to a tooth weakened by decay or infection. Crowns also play a vital role in sealing and protecting teeth that have undergone root canal therapy.
Porcelain Crowns – The advantage of all porcelain crowns over metal based crowns is their ability to reflect light like natural tooth enamel. As an added benefit, because there’s no metal substructure, the black line at the gums normally associated with traditional crowns is also eliminated.
