Crowns
A dental crown fits over the remaining part of a tooth, helping to strengthen it and making it look like a whole, natural tooth once more. Modern crowns are much less bulky than older ones, making them feel more natural, and they also do not have the old-fashioned metal edge at the gumline.
There are a number of reasons why we may recommend them. Your tooth may be very decayed and not strong enough to be filled any more, the top part of the tooth may have been accidentally damaged, or you may need one following root canal treatment. Crowns are also sometimes needed to help support a dental bridge.
We will need to prepare your tooth first, and will usually numb the tooth and the surrounding area with local anaesthetic. The next stage is to take an impression, or mould, of the area around your tooth. This will be used by a skilled dental technician, who will craft your crown so that it is a perfect fit. The technician will also ensure the colour of the crown matches your own teeth, so that it is virtually indistinguishable from them.
For the couple of weeks while the crown is being made, you will be fitted with a temporary one. .
Once your new crown is ready, we will fit it and bond it in place with a special dental cement.
Bridges
Bridges are a permanent and realistic looking way of filling a gap between teeth caused by one or more missing teeth.
A bridge is a false tooth which is held in place by the teeth next to it. It is usually made of a precious metal base such as gold, with tooth coloured porcelain bonded to any visible areas to make it look natural.
Most often, the two neighbouring teeth – one on each side – will need to have crowns fixed onto them. The two crowns are then joined together by placing the false tooth between them and cementing them in place. This is known as a fixed bridge.
Creating a fixed bridge is usually a good option if the teeth either side are strong enough to support the bridge, but are already crowned or have had large fillings.
Sometimes adhesive bridges can be constructed. These have a lot less impact on the neighbouring teeth because the latest bonding techniques are used to hold the false tooth in place.
