I was treated by Dr. Klein for more than 10 years. Almost every year, he can find something wrong with my teeth and had to do fillings and my teeth never get better. Then In 2009, he plans doing a crown on my two teeth. But he did a poor job that I have to do a root canal which cost extra $1000 more than planned.
That's my last straw. I switched dentist and my teeth has been very good since I switched.
By the way, I have Merck insurance but I always have to pay extra out of my pocket even for routine cleaning.
