Crowns & Bridges
A crown is a tooth-shaped cap that is placed over a tooth. It is used to strengthen and protect your tooth structure. Most crowns are made of a hard, white substance to help them look natural.
A dental bridge covers or "bridges" the gap between missing teeth.
After you lose a tooth, your dentist may suggest that you get a bridge. A bridge can keep your other teeth from moving out of place.
Once a bridge is placed, it works just like your natural teeth.
Types Of Crowns and Bridges :
Gold Crowns :
They are composed of a gold alloy and are mostly indicated for posterior teeth. The advantage of gold crowns is that minimal preparation is required on the tooth. Because of the high gold content of this type of crown, the crown is slightly malleable, being able to adapt to changes in your bite over time.
Metal-Porcelian Crowns :
These crowns are the most common type of crown used today. They are made of porcelain with an underlying metal substructure. This allows for the restoration to have strength and be aesthetically pleasing.
Full-Porcelian Crowns :
Full porcelain crowns are the most aesthetic of the three. They are able to very closely mimic the natural shadings of the tooth, in certain cases, being virtually indistinguishable. However, they are more brittle, and are more prone to chipping.
