Hollywood Smile dubai is a total makeover of your smile, i.e. a complete prosthetic reconstruction of both jaws using caps, veneers and, quite often, implants.
Smile involves placing dental crowns on all teeth, or at least on all visible teeth in both jaws, which means up to and including premolars.
The term comes from the eponymous movie mecca and is used to evoke the brightly bleached teeth of Hollywood celebrities.
