A bridge is three crowns permanently cemented to replace a missing tooth. Implants mimic your real teeth with an anchor to replace the root of your tooth which is then crowned.
A bridge is a permanently fixed restoration that replaces one or more missing teeth with artificial teeth. It literally bridges the “gap” where the teeth were. The restoration is bonded onto surrounding teeth for support. A bridge can be thought of as “3 crowns” joined together.
Another way to replace a missing tooth other than a bridge if an implant. An implant requires surgery to place that anchor and several months may be required for the bone to grow around the anchor and firmly hold it in place. After healing the anchor is basically fitted with a “crown”. An advantage is no other teeth need to be involved to support it as in the case of a bridge.
