Hi, my friend desires to be a model. She is pretty but she always runs away from photographs. She always smiles without showing her teeth. It might be because she has a gap between the two of her teeth in the forepart. These teeth are discolored too, and so she hates smiling. One of my friends suggested trying smile makeover from a clinic in Toronto. Is this smile makeover a good practice for teeth? Will this procedure show any reverse effect after a few years? Should we carry out this smile makeover in an interval of time to maintain the effect? Can we make out this smile makeover in one visit? Will this process makes the teeth more sensitive? Is there a necessity to carry out smile makeover treatment to all the teeth? Is this expensive procedure? What aftercare should be provided for the treatment? Please, give me genuine replies.
