A cosmetic dentist who has undergone proper training has taken postgraduate courses on porcelain veneers, as well as cosmetic dental procedures - such as laser dentistry, all-white restorations, and Invisalign. Patients should ask their potential dentist about the cosmetic courses he/she has completed. The American Academy of Cosmetic Dentistry is the most popular association for cosmetic dentists. Being a member of the AACD does not necessarily mean that a dentist is good, but at least it shows that the dentist is serious enough about his line of work to spend for a membership.
