Cosmetic dentistry is well-known for the wonders it can do, and dental crowns are one of these restoring dental miracles that have amazingly advanced throughout the years.
Dental crowns are the historical standards in dental restorations; they are used to treat damaged teeth. A crown covers the broken tooth to repair the strength and get rid of any discomfort that the damaged teeth may cause. For many years, these restorations were made entirely from precious or non-precious metals exposing a dull-looking dark tooth. There are currently three different types of materials that your dentist can use to restore your teeth with a crown.
Dental crowns can be made of ceramic, porcelain, or a metal. The type of crown used is generally determined by the extent of damage to the tooth and individual needs of the patient.
Metal Crowns,
As their name implies, metal dental crowns are composed entirely out of dental alloy. The classic all-metal dental crown is the gold crown; however, other dental alloys can be used. Metal crowns are typically chosen for those situations where great strength is required and cosmetic appearance is not a concern. Metal dental crowns are extremely durable and make a great option for back teeth.
Porcelain Bonded Crowns,
This kind of dental crown might be thought of as a hybrid between all-metal and all-ceramic crowns. With these crowns, a body of porcelain is applied to and then bonded onto a metal substructure in a high-heat oven. These crowns offer good strength characteristics and a white tooth-like appearance.
Dental crowns made out of porcelain are often used for damaged teeth that may be visible. A porcelain crown is fused with metal and is stronger than an all ceramic dental crown. However, a porcelain crown is not as natural looking as a ceramic crown but does make a more pleasing appearance than a metal crown.
All-ceramic crowns,
Ceramic dental crowns, as anyone could guess, are cosmetic metal free crowns, using tough ceramic cores under the more cosmetic porcelains. There is a range of techniques that can be used to fabricate all-ceramic crowns. Most involve the craftsmanship of a dental laboratory ceramist but some are created out of a block of ceramic on a milling machine. All-ceramic crowns are typically placed in those situations where aesthetics are of utmost concern. The disadvantage of this type of crown is that they aren't as strong as the other types. Although these ceramics give better strength than porcelain only Crowns, but not as strong or forgiving as metal-based crowns, but will give a superior cosmetic effect to metal bonded crowns.
Several types of ceramic cosmetic crowns are available. Some have an inner layer of very strong ceramic with an outer aesthetic porcelain layer; others are purely made from a single layer of ceramic. One of the most exciting materials which can now be used for cosmetic crowns is Zirconia. This tough ceramic can now be used to make stunning natural looking crowns that are also very resilient and attractive at the same time. A winning combination!
Remember : When looking at improving your WHOLE SMILE you should look at the arrangement, proportions and shape of the complete smile, not just individual teeth options. Thus you may benefit by a number of different treatment options that come together to improve the whole smile, without drilling too much tooth away. All Crowns will need replacing perhaps every 15-20 years on average, so the more good tooth preserved underneath the better, to allow future replacements to be done!
Successful Crowns:
Planning your smile makeover case is critical to success , as crowns are three-dimensional so the shape, colour, position and bite affect so many other factors in your mouth, have to go next to other teeth or bite against other teeth, so they look good and function well for years. That is why the opinion and treatment planning by an experienced cosmetic dentist is more important than say the materials used in the Crown. Crowns are hand-prepared, hand-made to specific prescription, such that despite having provided thousands of these over years, your cosmetic dentist in Preston has never made or fitted two identical Crowns ever! You are unique and so is the dental solution that suits you best.
