As the name suggests, a crown is a cap or covering for a tooth. It is used when your tooth is discoloured, cracked or broken, heavily filled or if fillings have been lost. The crown fits over the remaining part of the tooth, making it strong and giving it the shape and the contour of a natural tooth. They may recommend a ceramic or a porcelian fused to a metal.
A dental bridge is a ceramic structure, spanning the gap left by a missing or extracted tooth. A ceramic tooth (pontic) is fused between two or more porcelain crowns on either side of the missing tooth that serve as anchors.
The anchor teeth are shaped to accommodate the crowns and then a bridge is bonded securely over these teeth.
The pontic tooth and the crowns on either side are matched to the colour and the shape of your existing teeth.
