This comes off the heels of a really bad experience with a general dentist I went to for a few…read moreyears so let's get some good vibes going here with an awesome experience! I went to Dr. Giannuzzi a couple of months ago for a cosmetic procedure. Long story short, I took a falloff my porch, face planted and chipped a front tooth. I was devastated to say the least because my teeth and smile are my money maker. Ok, I kid So in speaking to a cousin a similar thing happened to him where he chipped a front tooth and recommended Dr. Giannuzzi for a veneer. We actually chipped the same exact front tooth and his veneer was FLAWLESS. I couldn't even tell the difference between either of his front teeth and the color match was perfect I made the appointment for the consult and was absolutely blown away by how efficient and friendly the front office staff was, how clean the office was and how wonderful the Doctor was. After this cosmetic procedure is complete I will go here for my general dental needs like cleanings and exams!

Horrible experience! I received a $1000. Estimate for dental work for my husband and myself and…read morethen after having all the work done they hit me with another bill for another $959! Beware!! Will never go back! If I had been given a $2000. Estimate I would not have consented to getting the work done. But funny, they waited till after our multiple visits and until the work was completed to hit us with another bill! Buyer beware, the actual bill we got was double what they estimated.

Saw Dr Grassa 6 months ago at Dr Romeo's office in Massapequa, since Dr Romeo who came highly…read morerecommended by my colleagues was unable to fit me into his schedule. When calling Dr Romeo's office for a F/u appt recently I was informed Dr Grassa had moved to Sayville so I called and made an appt. I saw him recently at Sayville Family Dentistry. My initial interaction with the friendly receptionist was positive. I then saw the hygienist who informed me I may need to return for two deep cleanings, although she had not taken X-rays yet nor had she done my cleaning yet. I was then seen by Dr Grassa who briefly examined me then told me I had a cavity in my wisdom tooth and the tooth required removal. Never showed me the tooth in question by using a mirror, never showed me anything on X-rays and never explained why he came to his conclusion. (I had X-rays done 8 months ago and have never had tooth discomfort). He told to see a dental surgeon. No referrals given for a dental surgeon, no documentation given as to why he reached his conclusion but just a very dismissive /disinterested attitude about my dental care as he just walked out of the room. I do not recommend this dentist and I already have an appt. with a new dentist. I should have seen Dr Romeo instead of wasting my time.

He is very Experienced (23 years in practice), Professional and personable. After repeating X-rays and examining my teeth, he determined that there was no need for "a cap" as suggested by Dr Grassa and no need for 2 deep cleanings as suggested by Arkna his hygienist. He did however have to reclean my teeth despite my having done a cleaning a week ago at Dr Grassa. When something doesn't seem right ALWAYS go for a second opinion!!

Of course I was nervous, he explained the whole procedure in detail at my exam, again on Saturday for the procedure and discussed the options one more time.

Can't say enough about their office and staff. Love my Dentist.... bet many people don't say that! If you need a great dentist come to Dr. Rahr in Kings Park NY. Nancy E

Went to this HORRIBLE LIAR years ago when he worked for a different practice. I went in for an…read moreemergency visit because I had a broken molar. I was new to the neighborhood and didn't have a dentist in the area. Unfortunately it didn't occur to me back then to research a dentist before going in. It was my first visit so he performed a full set of X-rays and told me I had 6 canaries and needed 4 root canals. I should have known better then to let him perform ANY work on me. While he had me numb he said "since you're already numb, I can do both root canals on the upper side." what a terrible idea it was for me to agree. It's now almost 14 years later and I still have pain on the tooth that probably didn't even need a root canal. The tooth that brought me to his office had to be removed completely five years later. Back to the reason he is a complete liar!! During a follow up visit for what he said was a tooth that needed a root canal, the dentist that was there that day said I just needed a small filling. I asked that dentist about the rest of the teeth that Dr. Riutta said needed root canals or cavities filled and he whispered in my ear "after today's visit don't ever come back to this practice, there's nothing wrong with the rest of your teeth." I found a wonderful dentist in the area and after that day funny enough it was almost 10 years before I had another cavity filled. Amazing how those other canaries just vanished!!! DO NOT LET THIS MAN WORK ON TOUR TEETH!!!
