This is more for my husband's recent experience.
We have been patients at the My Dentist (on Lindsey) in Norman since its beginning and before, when it was Dr. McDonald's practice. We have not had any issues with My Dentist other than them wanting to change appointment dates in a week's notice made for appointments made months in advance. Not the end of the world. Additionally they had previously installed a crown and had done other work on my husband and he did not have any problems. We had also recommended people to them. However things have taken a more serious turn recently, In Octoberish of 2013 my husband went in for his check-up. The check-up resulted in the doctor saying he needed a filling. My husband hadn't complained about this area, however he did mention his (previously mentioned) existing crown on the adjacent tooth on occasion would give him a "zing". The net result was the filling procedure being done on the adjacent tooth and My Dentist graciously said they would replace the relatively new crown at no cost to us after the doctor said she saw a crack in it. Long story short, my husband was in pain after the 2nd install of the temporary crown and then the permanent crown. Additionally my husband's bite has never been the same and after months of follow-up visits it still remains a problem. Specifically the crowned tooth and adjacent tooth with the new filling were/are the problem. At one point in October (on his way to Urgent Care on a Sunday while on the phone with the dentist describing his pain around his jaw and ear area) he asked if he needed a root canal and the doctor said no. Now (March 2014) and after many visits to My Dentist he was told recently by the dentist he needs a root canal on the tooth that had the filling. During his last visit (March 2014) to My Dentist they showed him his Octoberish 2013 X-ray saying it was healthy then they showed him the X-ray taken during the March visit indicating the failing root. To sum it all up, it is our opinion that the pain and need for the root canal is a result of the bite issues, crown and filling installation by My Dentist. It is unfortunate that such a long relationship with them has ended.
