Dental Crowns: What You Need to Know About Them

One of the main methods of dental restoration uses dental crowns. Crowns are tooth-shaped caps placed over teeth, often after a procedure that filed down the original teeth to a shape that can receive the crown.

There are several reasons why your dentist would recommend having a crown placed. The usual reason is to give a weakened tooth, usually through tooth decay, some degree of protection from further damage. With a crown, a tooth can once again be used to chew on food without worry of it cracking. Another reason for a crown to be placed is to restore a damaged or cracked tooth; this ensures that you look like a have a perfect set of teeth again.

The first step in getting a crown is to prepare the tooth. The dentist does by first applying general anaesthesia. Once it has taken effect, the dentist will then start filing down the teeth on its chewing surface and side to give space for the crown.

Crowns are moulded to match the shape of your teeth so having them installed will often take a while. While you’re waiting for your new crown to be completed, dentists often place prefabricated temporary crown over the prepared teeth. Porcelain crowns are the preferred material since these mimic the original tooth; however, gold, silver, and stainless steel crowns are also available. The next time you visit the dentist, he or she will then install your new crown by permanently cementing it in place.
