I chose to visit Red Hills Dental after I saw an Invisalign ad and once meeting everyone there, I quickly made them my primary dental office. I am happy with my Invisalign progress. Yesterday I had my first deep cleaning and I was very nervous. Dr. Do could not had made it any more comfortable. The topical solution used to numb my gums worked wonders and no needles were used! I will recommend Dr. Do and his staff to my friends and loved ones!
