Did you ever consider why someone calls their business ABA? Because it's the first name that shows up in the phone book. I regret choosing ABA. I went to ABA because their previous clinic was within walking distance to my house and I didn't have a car at the time. I was experiencing some mild discomfort in my upper molar and I wanted to get a check up before my dental insurance through my student benefits ran out. Dr. Mao did some x-rays and was quick to explain that I had not one but TWO teeth that required root canal surgery. I was in my early 20's at the time and I had never had dental problems until that point. I proceeded with the recommendations for surgery without getting a second medical opinion because I felt hurried to use my dental benefits before they expired and I was hopeful that Dr. Mao was acting in good judgement. It cost me over $2000 for the procedure. I started to experience significant throbbing pain in the root canal sites a couple of years after the procedure. I had hired a new dentist after Dr. Mao as something didn't feel right about his practice. My new dentist had my history of x-rays from Dr. Mao's dental work. My new dentist questioned why I had root canal surgery and explained that the x-rays indicated only a minor cavity in one tooth and certainly did not warrant root canal surgery. The dentist took a look at my teeth, took more x-rays and explained that the surgery was not completed properly and I had to have it corrected which cost me several hundred dollars in repairs. Point of this message: When a dentist tells you that you need surgery, ALWAYS GET A SECOND OPINION AND SHOP AROUND. They work for you, not the other way around. Some dentist's are excellent and some are willing to lie about your health needs and pull out your teeth unnecessarily if it means they make more money. Please go somewhere else and don't make the mistake I did. read more
