Dental Crowns
Teeth can get damaged by bite- related problems,tooth decay and dental fillings. These problems lead to cracking,wearing down and breaking of teeth. Dental crowns are designed to cover the entire surface of the teeth that are damaged to offer more protection and additional strength to the teeth. There are several types of dental crowns available in many cosmetic dentistry clinics in Essex today. These are ceramic crowns,gold crowns and ceramic-veneered crowns that are made of gold.
Porcelain and Resin Crowns
These types of dental crowns are made of reinforced composite resin or from pure ceramic. They blend nicely with natural teeth making them highly inconspicuous. They are bonded to the teeth using a new bonding technique which provides a very strong bond to the teeth. For the back teeth,the cosmetic dentist uses an onlay that has got a natural teeth colour. No metal is used with these types of dental crowns which makes them ideal for patients who have metal allergies.
Gold Crowns
Gold is a metal that is easy to mould to various shapes. This fact makes gold crowns a perfect fit for your teeth. Gold crowns have one advantage over porcelain crowns in that they do not chip.
Dental Crowns made of Porcelain and Metal
These are crowns that are made of porcelain that is fused to metal. The substructure is made of metal and the top layer is made of porcelain.
There are different types of porcelain that are employed in making dental crowns. These are the pressed ceramic porcelain and felspathic porcelain. Felspathic porcelain is the more common of the two and has been in use for more than 20 years. The major difference between the two is in the way they are manufactured. Although dental crowns add strength and durability to damaged teeth,there are certain advantages and disadvantages linked to the different types of crowns.
Gold Crowns-Advantages
Gold crowns are very easy to prepare and conform easily to the tooth contours. This means that the original tooth is largely left unchanged; a fact that makes them ideal for badly damaged teeth where any chipping can irreparably damage the teeth. Most people also tolerate gold very well since it is a highly inert metal.
Gold Crowns -Disadvantages
Gold is a very shiny metal;this fact makes gold crowns highly conspicuous .They are best suited for back teeth.
Porcelain Crowns-Advantages
Porcelain has got a natural teeth colour that makes porcelain crowns inconspicuous.
Porcelain Crowns-Disadvantages
Porcelain crowns tend to be thicker than gold crowns. This means that for a perfect fit,more chipping has to be done on the teeth's surface. Bonding between porcelain crowns and the teeth is also more difficult. Inflammation of the gums is also more likely to occur with porcelain crowns.
Fused Porcelain and Metal Crowns-Advantages
The major advantage of these crowns is that they have a natural teeth colour.
Fused Porcelain and Metal Crowns -Disadvantages
The metal substructure below the porcelain requires an opaque substance to make it less visible. With age,this dark line tends to become visible.
