Dental crowns have a variety of uses, from fixing a broken tooth or one at a high risk of damage to improving the appearance of a misshapen or discoloured tooth. Crowns also assist in replacing a missing tooth — holding a bridge in place or covering an implant. Your North York dentist will recommend the type of crown for you depending on the reason you need a crown and where it will be in your mouth.
Types of Dental Crowns:
As porcelain crowns match the shade of your teeth, they are ideal for improving appearances as well as repairing damage. For front teeth and for people with metal allergies, dental crowns made entirely from porcelain are best. For back teeth, porcelain fused to metal is a better option, as these crowns still look natural but offer extra strength. In either case, porcelain may eventually chip under chewing forces.
Stainless steel crowns are prefabricated, which means they are inexpensive and only require a single visit to the dentist. For this reason, they tend to be for baby teeth, as they fall out with the tooth. They are also common as a temporary crown, which patients can use while the dental lab creates their custom crown.
Metal dental crowns in North York can be made from gold alloy, palladium, base-metal alloys (like nickel and chromium), and other alloys. They tend to last longer than other types of crowns and can withstand biting pressure without wearing down. The downside of these crowns is their colour, which makes them unsuitable for cosmetic purposes.
This is another option that comes in the same colour as your teeth. Resin crowns are less expensive than crowns made from metal alloys and porcelain. However, they do wear down sooner and are more likely to fracture.
Some dental clinics digitally create zirconia crowns, in a single visit. This eliminates the need for a temporary crown.
