At first I like Dr. Berkin, he was friendly, quick, and relatively cheap. However, this blindsided me to the fact that he was not taking good care of my teeth. He did two fillings for me. Both had to be replaced soon. One in a year, which may have needed to be sooner. The other in a month. He did not get out all of the decay, which could have lead to an abcess. He also failed to take X-rays and did not see that two teeth need to be filled. My tooth chipped. I might have to have a root canal if this filling doesn't work. He is very painful. He won't wait until you are numb. It was so painful that I was shaking in my chair, and he wouldn't stop. Last time he left my mouth black and blue and in pain. My lip is still numb off and on. The prior time he hit a muscle and it was sore for weeks. Moreover, at the last check up he missed 6 cavities. Yes, six!!!! To top it all off, he failed to notice I was grinding my teeth.
