Crowns and Bridges

What are crowns and bridges?

A crown is a cap that covers a damaged tooth to restore its shape, size, strength, and appearance. It is typically made of porcelain, metal, or a combination of the two and is custom-made to fit over the prepared tooth. Crowns are commonly used to repair teeth that have significant decay, cracks, or fractures or to protect teeth that have undergone root canal therapy. Crowns can also be used to improve the appearance of discolored or misshapen teeth.

On the other hand, a bridge is a dental appliance that is used to replace one or more missing teeth. It is typically made up of two or more crowns that are attached to the remaining natural teeth on either side of the gap. The crowns act as anchors or abutments, and a false tooth, or pontic, is attached to them to fill the gap. Bridges can be made of porcelain, metal, or a combination of the two and are custom-made to match the color and shape of the natural teeth.

Types of crown

1.Ceramic Crowns: These are made of porcelain or ceramic materials and are highly popular due to their natural appearance and durability. They can blend in seamlessly with the surrounding teeth, making them an ideal choice for front teeth.

2.Porcelain-fused-to-metal Crowns: These crowns are made of a metal substructure with a porcelain outer layer. They are highly durable and can be used for both front and back teeth.

3.Base Metal Alloy Crowns: These crowns are made of non-noble metals and are highly resistant to corrosion, making them ideal for patients with allergies to other metals.

Types of Bridges:

1.Traditional Bridges: These are the most common type of bridge used in dentistry. They consist of two or more crowns attached to the teeth on either side of the gap, with a false tooth, or pontic, in the middle.

2.Cantilever Bridges: These bridges are used when there is only one tooth next to the gap. The bridge is anchored to the adjacent tooth, and the false tooth extends into the gap.

3.Maryland Bridges: These are also known as resin-bonded bridges and are used when the teeth on either side of the gap are healthy and strong. They consist of a false tooth attached to a metal or porcelain wing that is bonded to the adjacent teeth.

4.Implant-supported Bridges: These bridges are supported by dental implants that are surgically placed into the jawbone. They are highly durable and provide excellent stability and function.
