Crowns and Onlays


Crowns and Onlays are actually used to describe a few different procedures using different kinds of material. Crowns and onlays are ways to repair extensively damaged and weakened teeth. Crowns or onlays are manufactured in a dental laboratory. Compare this to the other option of having a filling (metal or composite) which is made by the dentist directly on your tooth.

In the most basic of terms, a dental crown is a tooth cap that is placed over a tooth thus covering the tooth to restore its shape, its size and much of its original strength, thus making it look more attractive and ’normal’.

People choose to have dental crowns for a number of reasons it may be due to decay that has permanently eroded parts of their teeth, to protect a weak tooth from breaking or to hold together parts of a cracked tooth. Other cases may be an accident or to restore a broken worn tooth, support a tooth with a large filling when there isn’t a lot of tooth left and cover misshaped or discoloured teeth.

There are also a host of different materials you can choose from for your dental crowns talk to Dr Tiang about what options are best for your teeth.
