A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. A bridge is a fixed dental restoration used to replace a missing tooth by joining an artificial tooth permanently to adjacent teeth or dental implants. Types of bridges may vary, depending upon how they are fabricated and the way they anchor to the adjacent teeth. Conventionally, bridges are made using the indirect method of restoration.

Material options are :

• Metal crown which are made of stainless steel or nickel free material
• PFM (Porcelain fused metal) which have metal inside and are layered with tooth colour
  ceramic.
• Metal free options are Zirconia and Emax. These advanced ceramics look fantastic and have characteristics of a natural tooth.

 
The advantages are:

• Restore your smile
• Restore your ability to chew and speak properly
• Distribute the forces in your bite properly by replacing missing teeth
• Prevent remaining teeth from drifting out of their position
