Dr. Nitzberg created a new dental appliance for my upper mouth to replace an old one. He did an AMAZING job, taking the time to make sure it was a perfect fit. The appliance is very comfortable and i have all beautiful white teeth! My kids and wife were so excited. They all said I looked like I was 20 years younger! I highly recommend Dr. Nitzberg as an excellent dentist, very talented and a super nice guy.
