What materials are used for dental bridges?

Dental bridges can be made from a variety of materials, each with its own benefits and drawbacks. Common materials used for dental bridges include:

1. Porcelain-fused-to-metal (PFM): These bridges have a metal base covered with a layer of porcelain, offering both strength and a natural appearance. They are durable and can be used for both front and back teeth, though the metal base may sometimes show a dark line near the gum line.
2. All-ceramic or all-porcelain: These bridges are made entirely from ceramic or porcelain, providing the best color match to natural teeth. They are an excellent choice for front teeth where aesthetics are a priority. However, they may not be as strong as metal-based options.
3. Metal alloys: Bridges made from gold or other metal alloys are extremely durable and resistant to wear. While they may not be aesthetically pleasing for front teeth, they are ideal for molars due to their strength and longevity.
4. Zirconia: Zirconia bridges are made from a type of ceramic known for its strength and durability. They are also tooth-colored and can be an excellent choice for both front and back teeth, combining aesthetics with resilience.

Your dentist will recommend the best material for your dental bridge based on factors such as the location of the missing tooth, your bite, and your aesthetic preferences.
