A dental crown is a tooth shaped cap that is placed over a tooth to cover, restore its shape and size to protect it and retain its natural appearance.
It is a type of dental restoration which covers the entire visible portion of the tooth. It is used to restore strength and to minimise the risk of further breakdown of heavily filled, cracked or fractured teeth. It is created in the laboratory by trained technicians based upon casts made from bespoke impressions we take of your teeth in our surgery. Once it is cemented into place, a crown fully encases the entire visible portion of a tooth that lies at and above the gum line.
Gold crown, crowns posterior gold
This type of crown requires the least tooth preparation of all the types of crowns available and is therefore the most conservative in nature. It is very strong and ideal for use in the teeth found furthest back in your mouth where the gold appearance is less noticeable.
There are numerous types of white crowns available at Victoria Road Dental Clinic.
Porcelain bonded to metal crowns
This type of crown is made up of a thin internal layer of metal, giving strength, on to which porcelain is reliably fused creating a natural looking crown. They can be used for front and back teeth and have an excellent performance history.
Zirconia is a biocompatible white opaque material and is very strong. The required tooth preparation is similar to a tooth receiving a gold crown and thus is very conservative. Due to the opaqueness, these crowns are limited to the back teeth and are ideal for those patients who grind or clench their teeth as they are extremely strong. They have an advantage over gold in that they are tooth coloured and can be stained for character.
Zirconia crowns can also be overlaid with porcelain creating highly aesthetic crowns with strong substructures. These crowns require slightly more tooth preparation than zirconia alone but provide excellent aesthetics especially when the underlying tooth colour needs to be masked. They are ideal to mask front teeth which have died due to injury and gone grey in appearance.
All ceramic crowns
These dental crowns are made of strengthened porcelain and contain no metal making them the most aesthetic of crown choices. As they have no substructure, they are not as strong as gold, porcelain bonded to metal or zirconia crowns and are therefore slightly limited in their use (i.e. they more suited to your front teeth). Following a thorough examination, your dentist will be able to assess if you are suitable for this type of restoration.
Your experienced dentist will discuss with you the best option and you can choose what type of crown you would like.
What is the dental treatment process at VRDC?
When preparing a tooth for a crown, normally two visits to the dentist are required. The initial appointment requires a full dental examination and preparation of the tooth from our experienced and highly knowledgeable team. The next visit involves the placement of the permanent crown. In some instances an a follow up appointment to assess the progress of the dental treatment.
Caring for Crowns
While a crowned tooth does not require any special care, it should be remembered that simply because a tooth is crowned does not mean the tooth is protected from decay or gum disease. Therefore, continue to follow good oral hygiene practices, including brushing your teeth at least twice a day and flossing once a day – especially around the crown area where the gum meets the tooth. Antibacterial mouth rinse can also help.
Application of dental crowns
When teeth that have been broken, or have been weakened by decay or a large filling, dental crowns are an ideal restoration option. The dental crown could be used for a number of other reasons, which include:
- To protect a weakened tooth from breaking, or to hold together parts of a tooth that has cracked
- To hold in place a dental bridge
- To restore s severely worn or a tooth that has already been broken
- To cover and support a tooth with a large filling, this is required especially when there isn’t a lot of the original tooth remaining
- To make a cosmetic modification
- To cover mis-shaped or severely discolored teeth
- To cover a dental implant
