Depending on the material used, two types of dental bridges are most often used: (#1) Porcelain Bridges and (#2) Porcelain-Fused-to-Metal Bridges. The two types are indicated in different situations because of their respective advantages and disadvantages:
Porcelain Bridges are dental bridges made completely of porcelain. Porcelain is an excellent material, since it is both extremely strong and aesthetic. Porcelain’s color and translucency closely matches enamel (the outer layer of a tooth), making porcelain bridges very natural looking.

Porcelain-Fused-to-Metal Bridges have metal inside and porcelain outside. The metal inside adapts perfectly to the teeth and provides strength and resistance to biting forces. The porcelain outside provides the beautiful appearance, matching the color and shape of your other teeth.
The main advantage of Porcelain-Fused-to-Metal Bridges is their strength and durability. Due to the high force on back teeth while chewing, Porcelain-Fused-to-Metal Bridges are typically recommended when a dental bridge is needed in the back of your mouth.
The main disadvantage of a Porcelain-Fused-to-Metal Bridge is that the metal can sometimes be seen through the porcelain close to the gum line, creating a grey line or grey shadow near the gums. This disadvantage is an aesthetic issue and does not affect your gums or the longevity of the bridge.
A special type of dental bridge is an Implant Bridge. An implant bridge is a dental bridge that is placed on top of implants to replace missing teeth. Dental implants are titanium screws that are placed in the jawbone in the area of missing teeth. Then, a bridge that looks and feels like natural teeth is placed on top of the implant screws to replace the missing teeth.
