Consultation fees for porcelain veneers vary from each office
Many offices will offer a free consultation, but that may only be a "sit down" and not a full examination or diagnostic records (xrays or models). Some charge a nominal fee, from $80 to $150. There is no hard and set rule or fee. I suggest making a list of offices that you feel are capable (experience and training are key), and call each office and ask. I would suggest meeting at least 3 offices to find one that you are comfortable with.
