Crowns are restorations that cover the entire chewing surface of a tooth. They can be made of gold or porcelain and are much more expensive than fillings.

So why have a crown?
Sometimes a tooth has been filled so many times or has been so extensively decayed that not much is left. Science tells us that if a tooth is over 60% restored the remaining tooth structure will eventually crack without protection. Sometimes these cracks will extend deep into the gum or bone and the dentist will need to operate to remove all the broken fragments of tooth from your jaw. If a long term solution is desired for a heavily filled tooth only crowning it will give protection against cracking or fracture.
