I had been a patient with Dr, Liebman for over seven years and just recently I was diagnosed with periodontal disease by a periodontist. It was beyond shocking to hear since I went to routine dental check-ups and cleanings and was never told that I had major problems. Needless to say periodontal disease does not happen over night, so I feel there was extreme negligence on the part of Dr. Liebman to prescribe the proper care and treatment for my gums. After having to have a LANAP surgery, that cost over 6,000 dollars I can only hope that I can reverse the damage that has been done due to the inadequate care I received from Dr. Liebman.
