Dental Crown or Porcelain Crown in Sutton?

Sutton Dental Centre and Medical Aesthetics is a dental practice located in the heart of Sutton, Surrey. Dental Crowns is the correct term for Dental Caps and can be used with Dental Implants.

A Dental Crown is a restoration that will cover the portion of your tooth or a Dental Implant which lies above the Gum Margin.

Once cemented in place the Dental Crown would become the new outer surface of your existing tooth. This is very different from Dental Fillings which only repair or fill in a portion of the broken tooth. Once the Dental Crown has been cemented the Crown-Tooth Unit functions exactly like the other natural teeth in your mouth.

 

What are Dental Crowns made of?

Dental Crowns can be made of:

 

1) Porcelain or Ceramics -

Porcelain Crowns offer the best aesthetics and real-life like translucency, which can exactly match your natural teeth. Porcelain Crowns are generally recommended for your front teeth where appearance are the most important factor.

 

2) Porcelain fused to metal or Bonded Crowns -

Bonded Crowns are hybrid crowns made by combining metal and porcelain in layers. The Dental Technician will first make a metal shell which will fit over your natural tooth and then a veneering of porcelain is fused to the metal to give it the tooth color appearance. Bonded Crowns are generally used for restoring back or molar teeth where appearance still matter but are not as important. The metal layer gives the Bonded Crown higher strength compared to the pure Porcelain Crown.

The disadvantages to Bonded Crowns is aesthetically they are inferior to pure Porcelain Crowns. Also the metal that lies underneath the crown's porcelain can sometimes be visualized as a dark line found right at the crown's edge. A dentist will usually try to position this dark edge just underneath the tooth's gum line so that it is not visible. But, if a person's gums happen to recede, this dark line can show, thus spoiling the crown's appearance.

 

3) Metal Alloy Crowns -

crowns are made completely out of metal and can be precious, semi-precious or non-precious. Usually these are made from a Gold or Silver alloy material. This allows to the dentist to have an excellent crown-to-tooth fit as the alloy is a very easy metal for the Dental Technician to work with. Metal Crowns are also very strong and hence can withstand the strongest biting and chewing forces. The main disadvantage of metal crowns is the poor aesthetic appearance

 

Why do I need a Dental Crown?

I get asked this questions many times. I often have seen patients who are seeking a second opinion if a Dental Crown or Dental Cap is needed.

The main reasons why a Dental Crown is needed:

 

1) Strengthening your teeth-

Dental Crowns are used routinely on teeth are have broken down completely, or have a very large cavity due to extensive tooth decay or teeth that have been Root Canal Treatment.

If the Tooth Filling is very large due to a large portion of your tooth breaking off or after removal of extensive tooth decay, then having the tooth filled in is not a long term solution. There is high risk that the Tooth Filling will break down or the tooth may completely fracture! Also once a tooth has had Root Canal Treatment it becomes more brittle and hence there is a greater chance of a Tooth Fracture. In order to protect the tooth from breaking your dentist would recommend a Dental Crown. This will sit on top of your tooth and protect it.

 

2) Restoring and Changing the Shape of the Tooth -

Once a Dental Crown is cemented on to the tooth is will form the new outer surface of the tooth. The Dental Technician when making a Dental Crown has the chance to examine and analysis the bite and jaw movement from a variety of angle, and hence can construct the Dental Crown to fit the ideal shape

Dental restorations play a major role in maintaining perfect dental health. Restorations which do not touch the opposing or adjacent teeth can leading to shifting of teeth. Also poor contact with adjacent teeth leads to food trapping areas which can cause Gum Disease and Tooth Decay.

 

3) Improve the Aesthetic Appearance -

Porcelain Crowns have fantastic aesthetics. Your dentist will choose a shade to match your natural tooth color. The best dental porcelain has subtle color variations, just as natural tooth enamel. The outside of an pure Porcelain Crown uses this this type of porcelain. While the inside of a pure Porcelain Crown is made from a much stronger porcelain, usually Zirconia (which you make recognize as a diamond substitute). Porcelain (like tooth enamel) is semi-translucent, meaning it can reflect and absorb light which gives it the real-life tooth like appearance. This properties allow Dental Crowns to have amazing appearance and improve appearances of teeth.

Crowns can within reason can allow teeth to be brought into alignment. Crowns can fix other cosmetic issues such as uneven teeth or uneven spacing between teeth. Hence a mouth which has wonky teeth can be straightened with Dental Crowns. Generally your dentist would discuss with you the various options of improving the aesthetic appearance of our teeth. Dental Crowns should be mentioned alongside Porcelain Veneers, Composite Dental Bonding and Teeth Whitening.
