Dental crown or less technically known as the “tooth cap” is a tooth like structure that is used to cover a natural tooth. This can be done in the event of extensive tooth decay, a broken or damaged tooth or to improve the cosmetic appearance of a tooth. A dentist can present you with a number of choices regarding a crown for a single tooth or a bridge, which is a restoration for a missing tooth. However, what’s best for you? Let’s have a look.
Speaking broadly there are two kinds of crowns, crowns with metal and metal-free crowns. Metal crowns are available in different combinations like gold and base metal alloys while metal free crowns are made from porcelain or zirconia. Let’s delve in a little deeper.
Zirconia based crowns are an alternative to porcelain. Fondly referred to as “ceramic-steel”, they have been proven to have better colour matching and strength than porcelain restorations. They can be used to flawlessly mimic the appearance of a natural tooth and do not cause any soft tissue interaction. Zirconia can be placed in areas of high stresses such as the posterior (back) teeth. When a stress occurs on a zirconia surface, cracking energy creates a transition in the crystals which seals the crack. Its resistance to traction and high compression strength makes it the most ideal material of restoration today, fulfilling all criterias of esthetics, function and durability.
