Cosmetic Dentistry » Porcelain Crowns & Bridges


A crown is a tooth shaped restoration individually made by a skilled technician that fits over the remaining part of a prepared tooth, increasing its strength and giving it the shape of a natural tooth.

A crown is sometimes known as a ‘cap’. Crowns are an ideal restoration for teeth that have been broken, or have been weakened by decay or a very large filling. They can be made of porcelain or gold or a combination of these materials.

A dental crown could be used for a number of other reasons, for instance:
  • You may have discoloured fillings and would like to improve the colour or shape of the tooth
  • You may have had a root filling which may require a crown to protect it
  • It may help hold a bridge or denture firmly in place


Besides having dental implants, there are two less ideal ways to replace missing teeth. The first is with a removable false tooth or teeth – a partial denture. The second is with a fixed bridge.

A dental bridge is usually used where there are fewer teeth to replace, or when the missing teeth are only on one side of the mouth. Bridges are either made of metal with a porcelain covering or preferably made of Zirconia. Zirconia has the advantage that it causes less sensitivity and with no sign of the dreaded grey line around the gum that some older metal bridges can cause. For many people, this is the downside of wearing a bridge.

A zirconia bridge is different in that it is produced from Zirconium oxide – the main advantages are a strong, stable and great looking bridge which blends in well with the rest of your teeth. Plus the material used to fabricate this bridge is ‘biocompatible’ which means that is kind to living tissue within your body and will not cause any ill effects, e.g. an allergic reaction.

You should replace missing teeth for a number of reasons. Your appearance is one reason. Another is that the gap left by a missing tooth can mean greater strain is put on the teeth at either side.

A gap can also mean your ‘bite’ is affected, because the teeth next to the space can lean into the gap and alter the way the upper and lower teeth bite together. This can then lead to food getting packed into the gap, which causes both decay and gum disease.
