Crown & Bridges
Crowns are an ideal way to rebuild teeth that have been weakened by having a very large filling or root filling, or may have discoloured fillings where we would like to improve the appearance of the tooth. The crown is cemented over the remaining part of the tooth, making it strong and giving it an improved colour, shape and contour to match that of a natural tooth.
Crowns are made of a variety of materials and new materials are being introduced all the time.
New porcelain materials such as Zirconia and E-max are available. The core of these crowns are as strong as metal but are tooth-coloured, resulting in stronger and more life-like crowns. These crowns can be made thinner and finer, so look more natural. E-max can be used for veneers and for small span bridges.
Porcelain bonded to precious metal – this is what most crowns are made from. A precious metal base is made and layers of tooth coloured porcelain are then applied over it.
Precious metal (gold and palladium) – these crowns are very strong, hard-wearing and require the least amount of tooth reduction, but are not usually used at the front of the mouth, where they are highly visible.
