Dental Crowns in Hampstead, London
A crown is a tooth-shaped "cap" that is placed over the entire visible portion of the tooth. A crown will look, feel and function just like any of your natural teeth. Crowns offer greater strength than simple fillings and also help to protect the tooth from further damage.
Why do I need a crown?
A crown can be required for a variety of reasons. These can be due to aesthetic considerations but most are due to a lack of remaining tooth structure. Most commonly, a tooth that has a large filling or has sustained a fracture will need a crown.
How are crowns made?
Generally, it takes two appointments to prepare and cement a crown. During the first visit, your dentist prepares the tooth to enable an impression to be taken and places you in a temporary crown. After the impression is taken of your tooth, the crown is custom-made by a specialised lab technician according to the dentist's instructions. At your second visit, the temporary crown is removed and the tooth is thoroughly cleaned and the new crown cemented into place.
What are crowns made of?
Crowns can be made from a variety of materials and are usually made by a technician in a dental laboratory. Dental crowns can be made out of ceramic (such as porcelain), metal (gold, metal alloy) or a combination of both.
The latest advances in ceramic now allow us to create crowns which are indistinguishable from your own natural teeth both in front and the back of the mouth. You and your dentist can decide which material will best suit your needs.
