His assistant was more helpful. He seemed to want to be in and out and was aggravated that my work was more complicated. I could hear him huffing.

I was excited to finally see a dentist and expected to be treated with respect. What a horrible mistake that was! first, Dr. Knapp asked me what I was there for, in a way that made me feel like i.was in the wrong place. why did I fill out that sheet saying what I wanted if he wasnt going to read it!?!? Then he told me I could either win the lottery, or play the insurance game if I wanted my teeth fixed. I havent smiled my natural smile in a few years!! And left wanting to cry. He didnt give me many options, used terms I dont know anything about, and did not listen to a word I said. He basically kept talking until all I could do was say ok and move on to the cleaning. I expressed my concern for the spaceS between my teeth getting wider, and he said there are a lot of people in hollywood who have that. He assumed I was talking about the one space between my 2 front teeth. Every option he gave me was expressed in a tone like it wasnt a good option. I was disgusted by his lack of professionalism all around! He asked me what I thought and I said O think I should just go home, this seems like a waste of time. I havent seen a dentist in 18 years because we didnt have insurance. I told him that, but he made comments multiple times about how I dont like to come to the dentist. I must have had an amazing dentist growing up because he surely didnt treat me like Dr. Knapp, and I didnt expect to be treated so poorly. My experience was so bad that my husband called to make sure he, or anyone else in our family, doesnt get Dr. Knapp, and to make sure I get switched to a new Dentist. I came in hopeful, and left upset, confused, and beside myself.
