Cabinet Dentaire

I went to this dentist for teeth whitning and after one hour setting on the chair, she told my your teeth will bright and shining for almost one year after 3 days the color of my canines and lateral Incisor became back yellow and my central Incisor normal white , I called her to check back she told me that is right, I went back to repair this ugly view. She told me I should pay again and she is not sure that I will get good result.I replied I won’t pay more for your uncertainty and my smile is really ugly now cause of this treatment.
