Dr. Haroun Rostami learned about structure as an engineering student, and now the prosthodontist uses the principles of good structure to rebuild patients’ smiles. He installs crowns to cover weakened or fractured teeth, and he replaces missing teeth altogether with dental implants or tic tacs. These prosthodontics not only look like natural teeth, but also function and feel like them. In addition, Dr. Rostami ushers teeth into single file with Invisalign clear braces and brings out their natural whiteness with Zoom! teeth-whitening treatments.
