I have been a patient of Dr. Landau for over 30 years and he's taken wonderful care of my teeth in…read morethe most professional and caring manner possible. Can dental procedures be expensive? Well, yes, but with Dr. Landau you know you are being treated by a skilled and experienced dentist using the latest technologies. From the time they recommended fluoride treatment at checkup appointments, I haven't had a cavity and I appreciate their foresight in making that suggestion. Dr. Landau and the entire staff are friendly, easy to talk to, open, honest and willing to listen. You won't find on the North Shore a better dentist or dental office.

This dentist told me that I needed expensive work done that was not really needed! Dr Landau said I…read moreneeded a scaling on all 4 of my quadrants ($850) due to deep periodontal pockets he saw. Said it was such a big job, I had to do it in 2 separate appts. I came in for first procedure of right side. I had some problems with side effects of the anesthesia later in day, He did not return my phone call for three days after my many attempts at leaving messages. That alone is alarming. So with that raising issues I had to see another dentist (actually 2 different highly qualified dentists) who both found that I did not have any pockets Dr. Landau saw. If he said both sides needed scaling and emphasized how bad they were.. then why was the other side he didn't do yet perfect without any signs of pockets? I refused to pay him for the half of the procedure he performed and he actually seemed ok with that -never perused me or sent a bill. That alone shows he admitted wrongdoing as he knew he couldn't argue or pursue this. I just hope patients can do their research to see the many dissatisfied patient reviews online. There have been many others just like myself that I wish I saw before I started with him. However I have notices that he seems to get many of these bad reviews removed from here. Also beware when you see a ton of rave reviews for doctors on who have bad reviews as they are putting up these bogus good reviews to balance out the bad ones. Keep in mind that there are usually few to no reviews for most doctors, even the good ones. People know who the well established top doctors are w/o Yelp. But don't be duped and fall for doctors on these review sites who have their friends and family post lots of good ratings to offset the bad ones. Just beware that this dentist is mostly motivated by money and not your best interest!
