I decided to have veneers and crowns installed on every tooth for cosmetic and functional reasons. I was 49-years-old at the time and the appearance of my teeth made me very unhappy. I looked like I was 39 and my teeth looked like they belonged to a 59-year-old.Dr. Siegel did extensive work in two stages; first the upper and them the lower teeth.I finally have a perfect smile. I may never have plastic surgery, but I can always be confident that I have gorgeous teeth.
