Dentists have been doing bridges for many decades. They have filled the spaces, but they have also had to carve down the adjacent teeth to do so. The dental patient then has to floss and clean around and under the bridge. If the dental patient has enough bone for a dental implant it is clearly the best option. The dental patient can maintain the implant tooth like he would a normal tooth. The adjacent teeth also remain intact. If I had the choice between a implant and a bridge, I would pick the implant.
