i received care from Dr. Kenneth Sacks back in the 1970's. I received many fillings in my mouth from Dr. Sacks. For most of the fillings done on my teeth, I was told I had 5 to 7 cavities in each tooth (he filled every molar in my mouth). I was always unaccompanied by a parent on those visits as his office was within walking distance. Even though I was told I had 5 to 7 cavities in each tooth, I never had any pain in those teeth. Upon complaining about this to my mother, she would say, "he's the dentist, he knows what he's talking about." During my last visit to Dr. Sacks for a checkup, I was told that I had four cavities in my bottom front teeth (which never bothered me). Upon hearing this, my husband told me to change dentists. I decided not to return to his ofice for this work. I did not see another dentist for 4 years. My checkup 4 years later showed no cavities in those teeth Dr. Sacks had told me I had had 4 years earlier. That was over 20 years ago, and I still do not have any cavities in those teeth he told me I had had cavities in. I do not, therefore, recommend him as a dentist as I distrust his judment and ethical practices.
