When a tooth is missing, a replacement tooth should be put into the open space in order to maintain proper dental alignment and health. For years patients were advised to set their desires aside and accept the limitations of an FPD(bridge). However, the most natural method to replace a tooth is to use an implant, rather than preparing adjacent teeth and joining them together with a prosthesis.
If you are missing a single tooth, one implant and a crown can replace it. A dental implant replaces both the lost natural tooth and its root without impairing gum health or damaging surrounding teeth.
