A dental crown is a tooth-shaped ‘cap’ that is placed over a tooth to cover it and restore its shape and size. It strengthens and improves the appearance of a tooth. When a crown is cemented into place it fully encases the visible portion of a tooth that lies above the gum line. Crowns can be made of porcelain, gold or a combination of both, depending on personal choice and location in the mouth. Your dentist will advise you on what is best for you.
The procedure for a crown is done over two appointments. The first appointment is to shape the tooth and take impressions to be sent to the laboratory to make. This usually takes up to an hour. The second appointment is two weeks after the first and is to fit the crown, this usually takes 20 to 30 minutes.
Crowns are prepared under local anaesthesia.
