This is a Negative Review of Dr. Pahlavan, Three years ago, Dr. Pahlavan replaced one of my crowns. She said it will be a zirconia crown. Later on when I had a check up, another dentist said this is only a porcelain crown, not zirconia which is much stronger. On another occasion, Dr. Pahlavan recemented a crown that came loose. Because there was too much cement place inside the crown, the bite was very high. Dr. Pahlavan adjusted the bite on the top and bottom crowns. As a result, she made a hole in the bottom crown. Later on a cavity developed in this tooth. As a result, I now need a root canal treatment and a new crown costing more than $3,500.00 Had she check the bite before curing the cement, this may never have occurred.
