A fixed bridge replaces one or more teeth by placing crowns on the teeth on either side of the space and attaching artificial teeth to them. This "bridge" is then cemented into place.
Bridges are beneficial because they feel and look like natural teeth. You might find they improve the appearance of your natural teeth on either side of the space. They’re also typically cheaper...
It can be difficult to clean around the tooth underneath the bridge. Bridges involve altering existing teeth. Also, a poorly fitted bridge could gradually damage adjoining teeth over time. In addition, plaque and bacteria could seep underneath the bridge, causing tooth decay or an infection.
PFM dental crowns, which is short for porcelain-fused-to-metal, are a type of crown that has a metal base which covers the remainder of the tooth. Then there are added layers of porcelain which are attached to the metal base. PFM dental crowns often leave a metal ring at the bottom of the crown that is quite noticeable, even to lay people. This metal ring is can become exposed when the gums recede. Additionally, The porcelain used can degrade over time, which can give the tooth a dull color inconsistent with the other natural teeth. Aesthetics is a big thing to consider when getting a crown on your teeth. PFM crowns rarely fully deliver in aesthetics. They are generally used for when a crown needs to withstand a lot of pressure or tension that often comes with chewing.
