Traditional treatment options for tooth replacement, Crown & Bridge and full or partial dentures, address the short-term cosmetic problem of missing teeth, but do nothing to stop bone loss. Crown & Bridge also requires that two or more healthy teeth be ground down to serve as abutments (posts) for a bridge, leaving them at a much greater risk for cavities and endodontic failure. If the original abutment teeth fail, more healthy teeth must be sacrificed to serve as posts, while you continue to lose bone beneath the bridge.
