Crowns@eine kleine dental
Crowns can be used to attach a bridge or protect a weak tooth from breaking. Crowns are created from a wide range of materials, which impacts the wearability and longevity of the restoration.
Crowns are used if the decay is so large that an amalgam or composite filling will not suffice.
Crowns cover the cusps of the tooth and hold the remaining tooth surfaces together
A dental crown covers the entire tooth with the crown margins close to under the gingival margin.
Crowns are made by grinding and shaping the tooth. Once the tooth is properly shaped an impression is made. The crown is then constructed in the lab.
It is then fitted, adjusted and cemented into place.
A crown should always feel like it belongs to you. At Eine Kleine dental we aim to get the occlusion right so that it feels comfortable and normal.
Crowns can be (a) made entirely of porcelain – the new generation of porcelain materials have more strength than their predecessors and superb aesthetic properties or (b) are constructed of a substructure of gold or non-precious metal with porcelain baked onto the surface of the metal. The metal provides strength while the porcelain matches the shade and contour for the teeth.
Crowns are often called “permanent” restorations. Permanent does not mean eternal. They are subject to extremes of temperature and chewing forces. Over time materials may wear down or fail and restoration may need to be replaced. The tooth-to-restoration margin is also subject to decay if plaque is allowed to accumulate
