A dental implant has several advantages when compared to other tooth replacement options. It functions more like a natural tooth and looks better, as well. A dental implant will replace a single tooth while not sacrificing the health of neighboring teeth. A tooth-supported fixed bridge is the other common treatment for replacing a single tooth. A bridge requires that the teeth on either side of the missing tooth be ground down to support the bridge. The dental implant replaces the tooth root, preserving the bone. When a bridge is used, the bone that surrounded the missing tooth can deteriorate. Dental implants work with the jawbone, keeping it intact and healthy with tooth restoration. A single implant looks better and is easier to maintain than a bridge. Gums can recede when a bridge is used, leaving the metal base or collar exposed. The reabsorbed bone under the bridge can make for an unattractive smile. If the cement holding the bridge washes out, bacteria can decay the teeth that the bridge is attached to.
