The crown of a tooth is that part which is visible in the mouth. An artificial crown is used to protect and restore a broken, weakend or heavily filled tooth. They are also used to improve the appearance of discoloured teeth.
Crowns are made of many different materials including metals and ceramics.
* We will shape thr tooth so that, when the artificial crown is fitted, it will be the same size and shape as a normal tooth.
* Preparation time will depend on how damaged the tooth is and whether it needs to be built up first
* If the tooth has died or there isn’t enough left to support the crown it may have to be root-fitted first, this is sometimes called ‘removing the nerve’. The crown is sometimes held in place by a peg or post in the root canal if a lot of the tooth is missing.
* We use a soft mouldalbe material to make an exact impression of what remains of the tooth that is to be crowned and the adjacent teeth.
* Our dental technician uses the impressions to make the crown.
* A temporary crown made of plastic or metal is usually put over the tooth until the permanent crown is made. You can chew on a temporery crown but it won’t be as strong as the finished one.
* When the crown is fitted, we may need to make small adjustments to make sure you can bite comfortably. The crown is tried on and then cemented into place.
* A crown is strong and can look and feel exactly like a natural tooth. The colour and shape can be matched to your onw teeth.
* Depending on the strength of the tooth underneath, a crown can last for many years if you look after your mouth and teeth and the crown is not accidently damaged.
* Crowns can also improve you appearance.
A bridge fixes a replacement tooth or teeth to one or more remaining natural teeth or implants. Some bridges have crown at each end. Others are fixed to the surface of the teeth next to the gap. Sometimes a bridge is only fixed to the tooth one one side of the gap.
Bridges are made of metal and procelain or sometimes just porcelain.
