I can promise you that these guys are quacks. As a medical doctor who reads x-rays with 2 brothers one in general dentistry and the other orthodontics, these guys don't have a clue what is going on. I went for a semi-annual cleaning. Though I have never had a cavity, I was told that I needed seven fillings and a crown (1500-2000 bucks of work). I have never had a cavity in my entire life. I didn't see anything on the x-rays though I am a radiologist and not greatly trained in reading tooth radiographs. I did show both brothers who disagreed 100% with everything said. I then became a patient of Dr. Henegar in Irving, TX who also disagreed with the diagnosis. My wife had a similar experience only for her they recommended more crowns and fillings with a root canal. \r
As a medical professional, I can promise you that these are two very dishonest people and they should be ashamed of taking advantage of their patrons. I highly advise seeking dental care elsewhere.
