Dr. Nagata and his staff are very professional and treat their patients well. They take the time to explain your treatment and answer any questions. I originally went in for full upper and lower implants in 2015. I live on Kauai and have been very happy with my new teeth. I recently had a slight problem with one implant post in the very back bottom right side. This happened just before the COVID19 restrictions and mandatory 14 day quarantine. I had to wait to fly on the first day the restriction of quarantine were lifted. Dr. Nagata got me in that day and did a great job of repairing the damaged post and tooth. I highly recommend him.

Very impressed with the professionalism and warm friendly welcome that Dr. Nagata staff provided. Colleen is really easy to work with and made me feel right at home. Marina did an phenomenal job with my 1st cleaning and love that she was able to educate me on the basic steps of dental hygiene, which none of my previous dentist offices provided to me in the past. Dr. Nagata was very kind and gentle and I really wish I was referred to him sooner. Thank you Dr. Nagata and Staff

I’ve been to many Dentists before and NEVER liked any of them……. Dr. Nagata and his team really make you feel at ease and a part of the family.  It was totally a great experience! State of the art equipment and a friendly staff makes this THE place. “where did you get that smile, beautiful smiles form Dr. Dennis Nagata” SO TRUE!

My husband and I had appointments this past Friday Feb. 26, 2016. He was in there for a cleaning, and I had 4 silver fillings replaced. I was nervous because I have heard that you can get really sick if the fillings are not properly removed. Dr. Nagata and his team put my mind at ease. They provided all of the necessary items needed for a safe removal. Dr. Nagata made sure I was comfortable, and made sure I was okay. Since Friday, I have noticed an increase in my energy levels, and I feel like a new person. Thank you Dr. Nagata and staff!!!! I will be recommending his office to my friends and everyone I know.

I came to get help to prevent my snoring and ease my sleep apnea. Dr Nagata offered a variety of treatments to help me including non invasive painless laser therapy to firm up my palate so it wouldn’t vibrate so much. I opted to go with the night appliance. Dr. Nagata’s assistant quickly took impressions of my teeth and in 2 weeks I got the appliance. It fit perfectly and I used it last night. My wife and I both slept well. Dr. Nagata saved my marriage! Actually Jesus did that but Dr. Nagata and his terrific team helped. I will definitely go back to see them again soon.

Dr Nagata and his staff are professional and helpful.  They go out of their way to make sure you’re comfortable and understand the work they are doing.  The equipment they have is state of the art.  I have had a couple of crowns done and a sleep appliance for snoring (which I can happily say I don’t snore now).  I highly recommend Dr. Nagata and his team!

Dr Nagata has been my dentist for over 30 years. He and his staff has always looked out for my comfort and ease while at his office. I am always amazed at his expertise and knowledge. If you are looking for a dentist that will always put your comfort and well being a priority along with great dental care then he and his staff of hygenists and assistants are second to none.

I was distressed and was looking for a viable option to fix my FRONT tooth. My previous dentist told me I needed an implant. WOW! BIG Bucks! I searched the internet and found Dr. Nagata. What a blessing! I didn’t need the implant. I totally trust Dr. Nakata. He is the BEST dentist and understanding. He’s also a great artist in giving you that natural looking tooth.

A necessary procedure turned out to be a treasure trove of high-tech professionalism and the beginning of a new smile. From the welcoming front desk to the confident personal care afforded by the dentist and his team, the experience was the best I’ve had. Your questions and concerns will be rewarded with an in-depth visual explanation in layman’s terms. Your requests are honored, and your comfort respected. A dental insurance plan can also made available to you. Your smile is their work of art.

Dr. Nagata is my dentist since 2007 and i’ll never look back. The service is always friendly and professional with impeccable ethics from the receptionist and the staff all the way to Dr. Nagata himself. I had chipped one of my front teeth on a Friday night and called Dr Nagata that night and left a voicemail. He called me back first thing the very next morning and met up with me at his office and fixed my tooth. I was very happy to not have to go through the entire weekend with a chipped tooth and be self conscious and embarrassed in public. This is just some of the icing on the cake because i can sit here and write all day about how much i love the expertise and care of Dr. Nagata’s entire practice. I saw Dr Nagata three weeks ago at his new location in Waikiki and i could not be happier with the new facilities as well. The service has always been great and now there is an even bigger and more beautiful space to match!

I actually started seeing Dr Nagata through a referral for sleep apnea to get a sleeping device. He recommended invisilign to me saying that he would recommend that, and I should get better sleep results if my teeth were a bit straighter. Every time that I have been there to see him he has always been respectful and patient. Josie has always been the assistant and she is a really sweet lady. I’d recommend him to others.

I’m a new patient with Dr. Nagata and my husband as well, I’ve been looking online for places that would have high tech equipment and an experienced dentist with laser treatment to take care of my cavities, I’ve always been traumatized about going to the dentist due to past experiences, where my anesthesia wouldn’t work and I would feel pain throughout my dental treatments, and lastly during a routine cleaning at the place I used to go, they rushed through my cleaning so much, poking my gums several times, until a piece of it came off, and was hanging in my mouth. I found dr. Nagata by reading online review from his patients, when I first walked in I was pleased with the cleanliness and the warmth of the reception, and surprised to see teas and lemon fresh water ready to drink, what a treat. After my first appointment I went in for a second time to treat a cavity, that I was avoiding to treat, because I was told by my previous dentist, that they’d have to break two of my front teeth to fix one, because it was in between on the side of one, and I was so afraid to feel the pain again, dr. Nagata assured and actually promised me I wouldn’t feel anything, and I didn’t, the anesthesia was done properly and he was fast at working on my tooth, without breaking any other like the other dentist said it was the only way, from this first treatment I felt nothing, I can only remember his assistant providing me with a great headphone and iPod to listen to music, so I’d keep myself calm, but since I had my own music in my phone I just borrowed their headset, and listened to music while dr. Nagata worked on my tooth, he made me feel relaxed and calm, I trust dr. Nagata to take care of my teeth from now on, thank you Dr. Nagata.

Dennis has always advised for the best in dental care, but has also been receptive to clientele’s request for optional care. I am limited financially to the aesthetic offerings of today’s progressive dentistry, however he has been patient with my requests and provided the next best care for my teeth and appearance. The office has also worked with my insurance coverages and scheduled to my benefit without missing timely dental care,

Every time I go to Dr. Nagata’s office for dental work or a cleaning, the staff is very professional and the office is spotless. They are very good about educating me about dental care while providing their services. I love that they are always on schedule. They not only take care of my teeth but they are genuinely concerned about my overall health. I always know I am in good hands when in their care.

Lamar W. from Orlando, FL (Source: Yelp)


I’m a new patient at the office, and I must say from the time I stepped into the office I have felt welcomed. The entire staff feels like a family and they listen to your concerns. I am not a open book but feel relaxed when I’m there. Dr. Nagata and staff have won me over and I am on board with there services and products and professionalism.
