The very first time I went to Dr. Warren, I had my teeth cleaned. Unfortunately, her hygenist chipped one of my veneers during a routine cleaning. I then had 3 fillings and two crowns (molars) done by Dr. Warren. The first 2 fillings were done by her dental assistant, who at the time I didn't know that she wasn't a dentist. The assistant did such a poor job that it was so painful for me to even bite into a soft tomato. I had to get the fillings removed and put in sedative fillings to calm the teeth down. I then had to go back for the third time to have Dr. Warren redo the fillings. It took Dr. Warren four times to get one of my crowns fitted correctly. The first 3 times, she overlooked my gum line and didn't make sure that the crown enclosed the entire tooth -- leaving room for sensitivity. On the 3rd and 4th time, I asked not to be numbed and beared through the procedure because I lost faith in her and wanted to make sure that the crown was fitted properly. Dr. Warren is a very nice lady, but beware --she often delegates some of her work, that should be performed by a dentist, to her assistants who are not. Dr. Warren needs to focus on quality and results.
