If you are missing several teeth, implant-supported bridges can replace them. Dental implants will replace both your lost natural teeth and the roots. Implant-supported bridges are permanently fixed in your mouth and will not move around like removable partial dentures. Dental implants look and function like natural teeth without needing the support of neighboring teeth. Because dental implants replace the root of the natural tooth, they preserve the jawbone and prevent bone deterioration. This preservation of jawbone helps to keep both the bone and gum tissue from collapsing, which can lead to an unattractive smile. In addition, with a traditional bridge, cement can wash out from underneath the bridge exposing the tooth, allowing cavities to form. Unlike a traditional bridge, implants do not get cavities.
