I feel slightly scammed by their guarantee your smile program. I feel as if they are extending treatment time unnecessarily after I have stated I am happy with the changes that have occurred thus far. Their initial agreement that treatment would last only until you are happy with your smile is not valid. It would also help if he did simple chart reviews before running in and out of the room for approximately 30 seconds of the treatment time so he could be slightly more knowledgable about what he recommended the previous appointment without the patient having to correct him.
