Great service and support with oral device. If you have snoring or sleep apnea issues, I would highly recommend Dr. Nagata. He and his staff are the “best”!
– Ronald W.

I believe it has helped to lower my blood pressure. I wake up less often during the night.
– Twyla C.

I’m so glad I did this procedure (Nightlase therapy). It was for me painless. No problems at all. And I can breathe much easier. I sleep better. IT’s just amazing. I just can’ t use the device (CPAP) at night. Thanks Dr. Nagata, you’re the best!
– Camille A.

Wow, so much better. I believe a much better alternative to CPAP machine.
– Daniela A.

Appliance work excellent! Took sleep study with oral appliance and there are no more issues with sleep apnea anymore.
– James N.

Much more comfortable than the previous HERBST appliance!
– Brian W.

Device works awesome, I slept way better!
– Robin S.

I wasn’t sure how effective the device would be, but after only a few nights I noticed an improvement in the quality of my sleep and no more snoring! It’s a great product and I’m glad I’m using it.
– Matthew M.

I like it much better than previous appliance and CPAP.
– Brian O.

The snoring stopped the first day. My husband was going to the guest room to get away from my snoring. Now he sleeps with me all night! I’ve had trouble going to sleep and sleeping all night before this appliance. Now I go to sleep and stay asleep.
– Beckie K.

I fall asleep faster now that I have started using the appliance, an average of 10 minutes. It’s very easy to adjust the appliance with the built in tool. My sleep is definitely much better.
– Phillip P.

This oral appliance is much better than wearing CPAP mask. Appliance is comfortable and sleep is much better
– Patricia K.

I started the oral appliance, not sure of how much my snoring would be reduced or stopped. I had been a heavy snorer and it was especially loud when I am over tired or slept on my back. Since using the appliance, that heavy snoring disappeared or reduced significantly. I wake up much more refreshed. If I fail to use the appliance I do not sleep good or wake up with a headache. It really works!
– Joseph R.

The Somnodent is a wonderful appliance. I feel that it has significantly increased my energy levels that were depleted due to sleep apnea. The device is comfortable to wear and I am able to sleep through the night with no discomfort.
– Cassie V.

I was diagnosed with OSAT. I was then recommended to Dr. Nagata to be fitted for a mandibular advancement splint. After being properly fitted, I have found my sleep hygiene has improved. The Somnodent is a great alternative to treat sleep apnea. Thanks Dr. Nagata!
– Roderick D.

Did not believe appliance would work. I gave it a try. Best night sleep I’ve had! I did not think I could sleep with the appliance in my mouth. I not only fell asleep right away, but slept through the entire night without waking up.
– William S.

Compared to my previous TAP device, this new devise is more precise and easier to clean and adjust.
– Gordon B.

Oral appliance is very helpful and easy to use. Much better than a CPAP. Also much more effective than an earlier appliance I had.
– Kevin M.

I love wearing my appliance. My sleep has improved beyond words! I’m dreaming again and feeling refreshed every day.
– Josiah S.

Awesome! Appliance is great. Don’t have to worry about carrying a huge machine or waiting for connectivity to come back up with CPAP machine. Sleep is improved dramatically and I don’t have any discomfort on my jaw. Thanks for your support!
– Oscar M.

No more complaints from wife about my snoring!
– Danilo E.

Slept thru first night with no snoring!
– George W.

Since using the device, my spouse says I have stopped snoring and I have more dreams!
– Ed N.

The Oral appliance have been more successful than my surgeries and have eliminated my sleep apnea. Sleeping better, and waking up less.
– Richard K.

The sleep appliance has boosted my energy levels. And is not uncomfortable like I thought it might be. I’m glad I finally got the sleep I needed.
– Kawika S.

The device works great!
– Aaron T.

Feel more rested and adjustments feel comfortable and effective.

“I can’t thank you enough for recommending the SomnoMed snore guard mouthpiece for my obstructive sleep apnea (OSA). Although my sleep study results @ Straub Clinic & Hospital showed a “mild” case of OSA, it concerned my wife enough to have countless sleepless nights where she’d intermittently monitor my breathing. She’d become quite alarmed when I’d stop for prolonged periods of time, only to sputter and spew myself back to “life”. My snoring was loud enough for our neighbors to mention hearing me! Acquiring a CPAP machine was strongly recommended as a viable option, but just trying the cumbersome face piece on proved to be too much for me to seriously consider. I was at a loss of what to do next. Your professional recommendation of the snore guard device has proven to be a “lifesaver” for me. Ever since I got the device, I have slept more soundly, more deeply and for longer periods of time and ultimately, awoken each and every morning feeling completely refreshed and ready to face the day. I no longer am groggy for hours or start to doze off after lunchtime or especially on my drive home to Kaneohe (which always scared me!)… The two-piece acrylic (?) mouth guard is quite comfortable and so easy to insert and wear each night. It’s not anywhere as bulky as I was anticipating and I can easily talk, drink, yawn and most importantly, breathe! My wife, Anna, openly thanks you, too! Best of all, I don’t have to wear any clunky headgear or hear a humming machine next to my head all night long. I thank you for your suggestion of this incredible product and am so glad it has made such a positive impact in my life. I highly recommend trying this product to any of your valued patients who suffer from mild to serious levels of OSA. I truly look forward to a lifetime of sleep-filled nights and better days! Mahalo and Aloha.

Frankie and I have known Dr. Nagata since before we were married over 23 years. You are the most professional and kindest people we have been involved with. Thank you for everything. Each person in your office is wonderful and especially caring. Even for me, a most nervous patient. Thank you and aloha!
– Kris Q. Honolulu, HI

I love my new dentist Dr. Chow. He is amazing and he made me feel so comfortable. I was embarrassed to go to the dentist because of the condition of my teeth, he was very professional and not judgmental at all. He is very awesome. I recommend him to everyone who needs a really good dentist. And I looooooove my dental Hygienist Erica. She is actually the one that recommended me to Landmark Dental. She is really good at what she does and she is super sweet and made me feel so comfortable and I was not scared. I want to thank her for helping to make my smile bright again. I actually love smiling now without feeling so insecure and discouraged. Thank you Thank you. I want to give a shout out to all the staff there. The office is nice and the workers are sweet, professional they all really love their job and the Ora in the office is so beautiful. It’s just amazing. Jackie, Taylor, And the rest of the staff I want to thank you for the amazing jobs you all do. I will definitely recommend you to everyone!! Happy Holidays and keep making smiles like mine shine.
– Jalen C.

Thank you so much Dr Nagata, Chow, and Zampetti and staff! A service.
Sincerely,
– A. Batungbacal

Awesome amazing outstanding very excellent dental group!!!!! These people crush it. Forget the LA dentist. High tech & awesome people!!!
– Ray L.

Best dentist I have been to. I needed a tooth extraction on a very decayed tooth. Made a appointment for exam and extraction in same visit. Fast and efficient, in and out in less than a hour! Very friendly staff that makes you feel comfortable. I was scared due to past experiences with different dentist, but Dr. Chow was calming and made sure I was comfortable. Definitely will be going back for cleanings and other teeth work
– Caroline N.

Great experience seeing Dr. Chow. Only dentist that has ever given me a follow up call to check in and see how everything going after getting numbed up and having a filling replaced. If anybody looking for a new dentist in Honolulu I would recommend Dr. Chow. Appreciate the TLC
– Manny F.

I want to thank you for your care and concern, expertise and resources in the renewing of all of the existing and missing teeth in my mouth. I also want to thank Colleen and Josie for all of their assistance to you, while taking care of me. Finally, I want to thank God in He’s leading me to you, so that you could restore my smile, my health and dignity.
– Roy O. Honolulu, HI

Dr. Dennis Nagata performed an implant surgery on my front tooth (#9). The procedure was quick, painless and with minimal bleeding. It was a very positive experience.

Dr. Nagata’s implant surgical team is highly skilled and experienced. Dr. Mauri, implant specialist, is very supportive and friendly. Dr. Wesley Sato, D.D.S., extracted my existing crown with ease. I appreciated his calm demeanor.

Thank you, Shannon, for your continued diligence. You chose the perfect color match for my flipper and the flipper fits perfectly… two very important features.

Thanks to Josie for always lifting my low spirits. Keep up being a good assistant to Dr. Nagata.

Thanks to Colleen and Jasmine for their never-ending goodwill and professionalism.

Lastly, I wish to thank Diko (hygienist). She has been very thorough, fast and friendly.

My continual battle for good oral health is finally improving through the efforts of Dr. Nagata and his hard working staff.
– Masae Choy, Mililani

Best dentist office ever, caring staff and dentist. I would never recommend anyone else to another dental office except to landmark dental
– Andrew R.

Im not a big fan when it comes to Dentist visit. But with Landmark Dental it was my first choice and i would say it was the best choice i ever made. On my first day when i went visit i can feel the aloha spirit, everyone greeted me along with a big smile.They were fast and really committed to there time. I did a cleaning for the very first time and it was the best feeling ever. There staff were really friendly and how they operate it was one of a kind. They also have a really clean and organized place. I would like to thank each and everyone for everything you guys gave me what I wanted which was ‘A BIG HEALTHY LOOKING SMILE’. I would also like to thank Dr Chow for all the recommendations and the hard work eventhough i have alot of tooth to be fixed. And for everyone out there who’s looking or still haven’t make up their mind where to go, I highly recommend this place they have really friendly staff, time commitment is awesome and clean looking healthy place. I would talk some more but let me stop here. So now is your chance why wait for, go get that healthy looking smile.
– Fuka T.

Thank you for a great experience. (I can’t believe I’m saying having dental work is a positive experience) I know I was in the best hands when my dentist shared that he’d recommended his own son (also a dentist) to study under Dr. Nagata. Thanks to everyone, especially Colleen, for helping to ease my anxieties. I couldn’t believe how fast and painless the sessions were. The best part – taking that first glance in the mirror and seeing BIG beautiful teeth. Thank you, thank you, thank you! A smile has always been my style to share with others, to boost and encourage. And now, my new smile gives me that boost of confidence and self esteem. Oh, did I say thank you? Well, thanks a million again and again.
– Lori P. Honolulu, HI

I just want to say thank you to Chris Chow and the rest of the people Landmark Dental Group who I must say just a delight to be around the energy is so warm and good there, I never been to a dentist place better than this one thank you so much guys aloha.
– Maunel L.

Lawrence did an outstanding job with my X-rays and cleaning. He is such a personable, kind person. Dr. Chow was also nice, and explained things very thoroughly. I would highly recommend this dental office. When I left here; it felt like I was part of a Ohana. ‘Thank you’ to the entire staff! Hubby came here too, and he said Lawrence gave him the best teeth cleaning he’s had at a dental office. We are two happy patients…
– Summer S.

My recent visit, I went in for a cleaning (Thanks Erica!) but they found that I had a missing filling so I would need to have that done. Instead of scheduling a return visit, Dr. Chow asked if I could wait around if I didn’t have any plans so that he could do it in between patients. I mean I’d gladly come back but he did save me another trip. Class act!
Thanks Dr. Chow. See you guys in six months
– Devin T.

First timer at Ala Moana Dental Group and I left very happy with the treatment and their staff.
I barely waited anytime after I filled out their paperwork as a first time client.
First thing they did was a full mouth X-ray, after that they checked all my gums and after explaining to me what they were seeing Ashley (the dental hygienist) did a very thorough cleaning and was very friendly and professional at the same time.
After that dr. Chow visit me and went over the full mouth X-ray I had just gotten he was very friendly and seemed very knowledgeable.
Overall it was over an hour visit (without any waits) and I will be coming back, already scheduled my next appointment!
– Sergi B.

I must admit, it was a distressing experience to face 2 cracked teeth during the holidays. After it was repaired with your special formula in January, I went to the Big Island to host a birthday dinner. Everything turned our super well and I could speak with confidence. Its been a full 2 months since the repair and it seems to holding up well. Thank you for the prompt and efficient care you and your staff gave me during my distress. That’s what I call excellent service!
– June S. Honolulu, HI

Dr Chow was my Primary Dentist for 5 when I used to live here on Oahu. So while on vacation with my parents and my dad had some dental issues and asked if there there was a dentist he could see, I immediately recommended Dr Chow. There were able to see him almost within a day. It relieved dad’s anxiety and averted a dental crisis while on vacation. Dr Chow was great and I would literally trust him with my family’s health!
– Chacktin L.

Friendly staff that are very helpful and do their best to accommodate your schedule. Beautiful office, clean and decorated for the holidays! They even have coffee 🙂 major win. Validated parking. They ran my estimate before performing the service so I would be prepared for my bill which was awesome and no other dentist office had done for me in the past. I believe there are four dentists working out of this space. Thanks to all the yelper helpers out there who recommended this spot!
– Carley P.

Dr. Chow and hygienist Marina were very caring and taught me things I didn’t know before during my 2 visits. The price is not cheap but it’s definitely worth it because the people here are enthusiastic and genuinely care about the patients. I’ll be back!
– Amy Z

The staff here at Landmark Dental Group is fantastic! Whenever I have a dental emergency they are able to see me ASAP and take care of the dental work that I need! A
– Shawn T.

What a sweet, funny and competent dentist! Going to the dentist is never fun, but the staff and Dr. Chow made me feel comfortable and in good hands.
– Vivienne G.

I was lucky to get the appointment the same day I called. The stuff was friendly and efficient, the wait was short, and the lobby was nicely decorated and warm. Puts you at ease when you’re gonna have someone in your face. Like Inside you face, has to be top uncomfortable experiences but here it was quick and relatively painless. I thought my last dentist in NYC was modern but heading to towards the back I saw a lot of newer versions of stuff I’ve seen. There office looked very polished and modern with multiple stations, I was directed to sit at one towards to back. Their technology helped diagnose everything quickly and efficiently. I had a 38 year old baby tooth that had to go. they x rayed me immediately. The images were instantaneous and clear on the screen. Dr. Chow reviewed them and discussed my options, recommended extraction of the tooth. He numbed me up, came back, the whole thing was done relatively quick. I remember the old days of two hour dentist trips. The extraction was really fast and clean. I was surprised how quick. The baby tooth wasn’t deeply rooted. I have to make a follow up appointment for my dental implant. But it was a great experience.
