I had a space between my teeth on my upper right side because of a tooth I had extracted years ago. The space was visible every time I smiled and I became really self-conscious. I had recently moved to the Boston area and was looking for a dentist that does great cosmetic work. I had heard about implants in one day and was suprised to find out that Dr.Hart performs this procedure. I had the implant placed in only one session (one dental visit) and I am really pleased with the natural looking results. My gap is finally gone. I would recommend Dr. Hart for implants or other cosmetic work to anyone reading this.
