I just moved to Chattanooga and found Dr. Armstrong on a recommendation. First visit was great with great staff, friendly and professional. My second visit was more in depth and I was very nervous about some minor surgery that had to be performed! It was awesome! I was so nervous, but Dr. Armstrong, his assistant and Munford (office dog/pet) made me at feel ease and pain free throughout the entire procedure! I highly recommend Dr.Armstrong and his staff at River City Dentistry if you’re looking for a dentist….10 out of 10 on all levels.

It’a truly unbelievable to think that dental experience can be enjoyable, but remarkably Damien and his staff made it easy. From when you walk in the door to leaving you couldn’t feel more comfortable, and you feel it’s more of wellness visit than a normal mandatory visit. Compared to my last dentist I felt I was in a time warp with all of the use dated high tech dental equipment. IT WAS EASILY THE BEST DENTAL EXPERIENCE OF MY LIFE.

In some cases, whitening alone cannot give you the harmonious, bright smile that you want. Our dentist provided durable, natural-looking porcelain veneers that transformed the appearance of his smile and improved his overall confidence.
