Top-shelf professinal! Dr. Patrick Nicosia was my periodontist for 17 yrs (till I moved to another state) and I still have all but one of my teeth, in spite of a problematic prognosis at the onset. Dr. Nicosia did my implant that went perfectly....I've never had a problem with it. Professional care and superb quality. Hygienist also top-shelf! I'm deeply indebted to the personnel in this professional office, and in Dr. Larry Byrd's office and Dr. J.F. Lopez's office, all in Houston---I have my teeth and healthy gums and home-care instructions and follow-ups that have helped me to make sure I am doing the best job every day.
