The structure of a tooth has three distinct layers. On the outside is the hard enamel that protects the more sensitive inside layers of the tooth. Directly inside the enamel is the dentine which is a slightly softer material that surrounds the dental nerve in the centre. If the outer protective enamel layer is damaged either through decay or as the result of an accident it can become necessary to provide the tooth with an extra layer of protection. This usually comes in the form of a tooth shaped and coloured dental crown that is fixed over the top of the damaged tooth.
Dental crowns cover all parts of the tooth exposed above the crown to seal off the sensitive inner parts of the tooth to stimuli such as hot or cold food which can be very painful. Crowns are usually made from porcelain or a mix of porcelain and metal (although increasingly they are made solely from porcelain as technology improves). This makes them very resistant to breaking and staining and also provides a very lifelike appearance.
In the past, some dentists were reluctant to fit dental crows unless absolutely necessary because they involved the removal of otherwise healthy enamel but recent computer technology has allowed the manufacture of thinner, stronger porcelain crowns that require minimal enamel removal.
Leeds dentists can fit dental crowns manufactured using the latest technology to protect damaged teeth and restore the cosmetic appearance of stained or worn teeth using a thinner crown called a veneer. If you have a damaged tooth that is causing you pain then make an appointment to ask about dental crowns.
