What Are Dental Crowns?
A dental crown is a tooth shaped “cap” that is fitted over a tooth to restore its strength, shape and size and to improve the tooth’s appearance.
A crown may be needed to restore a tooth that has already been weakened by decay, or to restore an already broken tooth or a tooth that has been worn down.
A crown can be also used to hold a dental bridge into place, to cover misshapen or severely discoloured teeth, to cover a dental implant, or to just make a cosmetic modification.
Treetops dental surgery use all porcelain crowns for cosmetic treatments as they provide a better natural colour match than any other crown type.
Frequently Asked Questions About Dental Crowns
Preparing a tooth for a crown will require a few visits to your dentist; this will usually involve examining and preparing the tooth. During these visits x-rays may be taken to check the roots of the tooth receiving the crown is healthy, if so the tooth will then be reshaped to make room for the crown to fit properly, a digital impression will then be taken of the tooth so the crown can be made in a dental laboratory. In the meantime a temporary crown may be fitted for you, until the permanent crown has been made; this is normally fitted using temporary cement. Then once the colour and fit of the permanent crown has been checked and is agreeable, a local anaesthetic will be used to numb the tooth while the crown is cemented into place.
On average a crown would last between 5-15yrs, this timescale will depend on how much wear and tear the crown is exposed to, for example how well you follow good oral hygiene practices, and also you own personal mouth related habits such as teeth grinding or teeth clenching.
While a crowned tooth does not require any special care, remember 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, flossing daily — especially around the crown area where the gum meets the tooth.
