Need a tooth replacement? You should consult with a prosthodontist, a dentist who specializes in the restoring and replacing broken and missing teeth with artificial substitutes or prostheses. A prosthodontist is trained in making artificial replacements or prosthodontics for missing or damaged natural dental structures. This can be as simple as making a crown for a damaged, decayed or malformed tooth or it could involve the design and fabrication of facial parts lost to cancer. Most of the time the job of a prosthodontist is somewhere between these two extremes.
