Dental Crowns & Bridges
Crowns and bridges are porcelain or metal teeth, that cover over your existing teeth. They are fixed to your teeth and can only be removed by your dentist unlike dentures which can be easily removed from the mouth.
A crown or hollow cap is used to cover the top of a tooth which has become damaged or decayed to a point where it cannot be restored by just filling. The crown recreates the shape of a broken down tooth allowing it to be useful in chewing. They also improve the appearance of the tooth.
Crowns are made from various materials with gold and metal alloys offering the most strength. Gold and metal crowns are mainly used for back teeth which are used most when chewing. Porcelain or ceramic crowns are not as strong but they can be colour matched to the surrounding teeth which, is excellent for the appearance of the front teeth. An excellent compromise is a metal structure with porcelain on top which is tooth coloured and strong.
The dentist may suggest a bridge if you have a tooth or teeth missing. A false tooth is used to replace a tooth that you are missing. The false tooth is attached to one or more of your existing teeth by a crown or a metal wing.
Bridges are also made from various materials which vary in both appearance and cost. Ceramic and porcelain bridges like crowns can be colour matched to the same colour as the surrounding teeth.

How Are Crowns Placed
Before a crown can be fitted the dentist has to make the tooth smaller so that the crown will fit over the top of it. This is done by reducing the tooth similar to having a filling done. They will then create a mould by taking an impression of the teeth which can be sent to the dental laboratory lab where they will create the crown using the material requested by you and your dentist.
If you have chosen a tooth coloured material, your dentist will choose the appropriate colour shade. Your dentist will make and fit a temporary crown which will remain in place until the permanent crown is received from the lab.
At the next appointment your dentist will remove the temporary crown and fit the permanent one, making any minor adjustments to ensure that positioning and bite are correct.
How Are Bridges Placed
The creation and fitting process for a bridge is the same as for a crown but one or more teeth either side of the space will be prepared.
Crown & Bridge Care
Crowns and bridges are designed to last a long period of time but it is important that the teeth and gums around the restoration are kept healthy and free from disease. Good oral hygiene, thorough daily tooth brushing, is very important to make sure your crown or bridge will stay disease free and last a long time. Using dental floss or interdental brushes will keep hard to reach areas around the crown or bridge and below the gum line healthy too.
If crowns and bridges are not cared for, the tooth surrounding them may become decayed. Gum disease and treatment of gum disease may cause the join between the tooth and crown to be seen. This will give your crown and bridge a very poor appearance.
