A dental crown is a “fixed-cap” made of porcelain, porcelain and metal, or gold. It provides full coverage of a tooth like a “hat” It can be used to restore the strength, shape and size, and improve the colour and appearance of a tooth.
A crown may be needed in the following circumstances;
when a tooth has cracks and/or fractures. A crown can protect the tooth from cracking further and preventing bacteria entering the tooth. This may prevent a tooth from needing to have root canal treatment or needing to be extracted.
teeth with very large fillings with very little healthy tooth structure remaining. This may support the tooth and prevent it breaking further therefore preventing the need for an extraction.
teeth which have had root canal treatment. This maintains a sterile seal on the tooth after it has been treated and helps to prevent it splitting or breaking.
to change appearance of misshaped and discoloured teeth.
