Los Angeles dentist Dr Anthony Mobasser specialises in cosmetic dentistry and works "like an artist" with each patient, he recently explained.
The first step he takes is to evaluate teeth and gums to ensure no existing problems might hamper the work. This means he can start the procedure "with a clean canvas".
Dr Mobasser then uses Leonardo Da Vinci’s Golden Ratio to make certain the new smile is even and proportionate.
Digital photographs, aesthetic wax-ups and study casts might also be employed as he analyses a patient’s teeth and decides on how to improve it.
In addition, for those who want to create a younger look, the dentist makes use of tooth whitening.
Dr Mobasser is based in Beverly Hills and, according to the Celebrity Dentist website, has treated a number of famous faces. His other specialities include porcelain veneers and crowns.
He recently expressed agreement with a US News and World Report poll that discovered 50 per cent of Americans were unhappy with their smiles.
