PATIENT REVIEWS

I hardly ever write a review, but I do want to let others know about the people at Garrett Hayashi, DDS’ dental practice. I interacted with four people, and each of them–the person at the front desk, Dr. Hayashi, his assistant Lori, and the hygienist Annie–were great. It was my first time there, after a bad experience at another office. Completed all the paperwork online, so all I had to do was sign when I got there today. Didn’t have any cavities (yay!) and so haven’t yet had any repair work done by Dr. Hayashi, but his manner and the fact that I’ve already learned a lot just from talking to him, assure me that he knows what he’s doing. His assistant Lori used digital x-ray and photography devices expertly while we chatted about nephew graduations and travels. But what most amazed me today was the extraordinary level of care taken by the empath hygienist, Annie, as she performed an overdue cleaning. In her hands, even the sonic instrument she used caused no discomfort at all. I can tell you that this is a first for me. Truly professionals, all.

I once read an article about the most and least satisfying jobs in America. The most satisfying was hair stylist, they make you look good, feel good and typically serves as your unofficial therapist. The least satisfying was dentist, cause most people hate going to the dentist, tooth pain and needles aren’t the best to be associated with. Plus you can’t be having deep conversations while having work done in your mouth. I’ve always had a phobia going to the dentist from being traumatized from being strapped down in the dental chair as a child, while having dental work done. I would cry the whole way to the dentist, I’d imagine the same way a dog fears the vet. Then enter Dr. Hayashi and his amazing staff! I now look forward and get excited about going to the dentist. Over the years, Dr. Hayashi, Jan, Nancy, Jovi and Lori have not only become friends but they feel like family. They are just so genuinely caring to their patients it’s heartfelt. Their appointment system sends you an email and text to remind you of your appointment and confirming is just a click away. Whether it’s a regular cleaning with Jan the hygienist, she always has the biggest smile and best hugs. I love her so much! She is always so thorough and takes time to give you tips on brushing and protecting your gums from receding. A visit with Dr. Hayashi for any dental work is always a pleasant one. Over the years, I’ve had to have some fillings replaced, my teeth filled in where my gums had receded, a root canal (was referred to a great specialist), two crowns put on (they have a machine that makes the crown in house and you get it done in the same visit, no more temporary crown to deal with). A chair that massages, say what?? Can I just say, I HATE NEEDLES, so whenever I need to be numbed up for dental work, it’s never my favorite. Dr. Hayashi does it with such care and expertise, I barely even feel the prick! He’s called in the evening after some major dental work just to check up on me. Who does that?? So appreciative of his personalize touch! Dr. Hayashi and Nancy the office manager always explains billing clearly so you know what to expect. I remember my first few visits when I had to have a lot of dental work done due to not going to the dentist for years. The bill was going to be very costly. Nancy went to work and learned that my insurance coverage from the previous year could carry over per my plan because I hadn’t used it. That saved me SO MUCH money. We would time my appointments to best take advantage of my insurance as it renews each calendar year, prioritizing what needed to be done first and what could wait. I felt so grateful that she took that extra step to care about my pocket. There’s been a few times I’ve needed to go in for an emergency appointment and they always manage to fit me in within a few hours. Parking is validated in their garage and the entrance to it on Alakea Street. I really can’t say enough positive things about Dr. Hayashi and his team. In life, finding a doctor and dentist that you trust and can rely is critical. I am so lucky and blessed to have found Dr. Hayashi’s office. They absolutely come with my HIGHEST recommendation!

Ive had a dental phobia and previously skipped the dentist for at least 10 years. A few years ago my teeth had been botherinng me so seeking dental work was an absolute must. 🙁 I had a wisdom tooth pulled, a root canal, cavities filled, 1 tooth crowned and another extracted. This work was not done by Dr. Hayashi but I sought Dr. Hayashi’s expertise after recommendation from my gf. Apparently the tooth that was extracted was not completely removed and was causing me pain. I called Dr. Hayashi’s office on Monday, went in on Tuesday for xrays and complete extraction of that damn tooth and was told to come back on Wednesday for a cleaning. Wednesday morning Dr. Hayashi personally called me to see how I was doing! This blew my mind and made me feel like he cares about his patients! By the way, the tooth extraction went smoothly and the most I felt was the numbing needle. Annie the hygienist did my teeth cleaning and was the sweetest! Not judgemental at all and made the experience less stressful than ive remembered with other hygienists. Minimal pain, mostly due to cold sensitivity but other than that, it was great!! My teeth looked 100 times better than before! Thanks, Annie, youre the best! I go back to see Dr. Hayashi so we can work out a treatment plan. If any updating needs to be done in the near future, ill certainly be back to drop by 2 cents! 🙂

I’ve been seeing Dr Hayashi for years now and really happy with him and his staff. Finding a great dentist is like finding gold. What I like about Dr Hayashi is that he operates smoothly, confidently and efficiently when performing dental procedures on you. That is only accomplished by a highly trained Dr and staff. Dr Hayashi’s office has gotten my dental health to a level where my visits are basically routine (cleaning, xrays, etc.) They are very involved with making sure you are on the right track to excellent dental health.

I’ve been coming to Dr. Hayashi’s office since 2009 and never thought about switching to another dentist once.  Dr. Hayashi, Jan, and all staff in the office are so wonderful and very courteous and I really love coming in this office.  I was never recommended any procedure at check-ups and cleaning.  Just the other day, I accidentally chipped my front tooth and called him first thing next morning.  He asked me to come in the same day and the procedure took only 10 minutes! It was quick, painless, and so easy.  Dr. Hayashi is a true professional and that’s precisely why I’ve been coming to his office for the last ten years.  I also recommended him to my husband whose condition got worse after receiving dental work at other dentist office.  He was in pain for months but Dr. Hayashi was able to fix everything.  Three other current and former colleagues of mine also go to his office and they all love him 🙂

I had been thinking of changing dentists since I was not enamored with Gentle Dental. The last straw was when they cancelled my cleaning appointment – again – because they are ‘going through some changes.’ Fellow yelper, Susan S., had recommended Dr. Hayashi to me and yesterday I called them to see if I could get in to see them soon. They brought me in immediately to do the xrays and exam and today is my cleaning. That, my friends, is customer service! My exam with Dr. Hayashi was very thorough and he spent quite some time going over my xrays and telling me the good news (no cavities) and the bad news (need a deep cleaning). Nice clean office in a building across the street from where I work. Friendly staff. I don’t think it gets any better than that!

My teeth have forever been “a work in progress”, and I’ve visited many dentists, but Dr. Hayashi and his team are the best and greatest I’ve ever experienced. His staff and team are always friendly and welcoming. They always want to make sure you’re comfortable and not in any type of pain if they’re working on your teeth. Dr. Hayashi is very straightforward, but nice. He offers a wide range of services, including the regulars like fillings and teeth cleaning, as well as other more specific services like invisalign, crowns, and removal of wisdom teeth. He ALWAYS asks you if you’re comfortable or can feel any pain every step of the way and he walks you through what he’s doing and the process that he’s going though while he’s doing it. This helps me to know what he’s doing and what to expect. Also, after some particularly complicated dental procedures, Dr. Hayashi called me personally the same day to make sure I felt okay. I thought that this was a very nice gesture. You should definitely talk to him and tell him your expectations and wishes, and he’ll do his best to accommodate you. My dad and I made it clear to him that your teeth are your only set for life, so to please use the best practices and materials, even if it was costly, and Dr. Hayashi did that as well as worked out the best course of action factoring in insurance, cost, and work. I have never been a regular at any dentist, but Dr. Hayashi and the gang have actually made me into their regular customer. I could not be happier with the work that has been done and with their dental practice.

Dr. Hayashi provides quality and genuine dental service and his staff are friendly, gentle, and very skilled. I’ve been at the mercy of inexperienced technicians before, and know the difference between “practice” and professional dentistry, and the people in this office are among the very best.

Have had a wonderful experience with Dr. Hayashi and his team. The staff is warm and welcoming – perfect for those with dental anxiety like me! I had to have 2 fillings replaced and the Dr. and his staff were very kind and took time to understand my fears and listen to my concerns about the procedure. I was so numb afterward they had difficulty adjusting the bite on one side, so when I called the next morning, they saw me right away at no charge to adjust the filling. Highly recommended to anyone who needs a good dentist in Honolulu!

In the middle of a COVID pandemic, I had a dentist appointment. I know Dr. Hayashi usually has the best equipment and best dental services, so I was curious how they would handle COVID. What a great process! Here’s what I noticed: – Lots of hand sanitizer once you walk in – They immediately check your temperature and oxygen levels upon walking in – Fill out a short form re: covid – No magazines or any common things that can shared is present in the office – I noticed the front desk immediately wiped down every surface I touched (pen, clipboard for form, etc) – When getting my teeth x-rayed and cleaned, Jan wore a full face shield, goggles, and mask – They have earplugs for you to use as they use a big vacuum system near your mouth when cleaning so that everything is sucked I think it is amazing how they’ve adapted to COVID! Also wanted to say I’ve been coming here for years and am impressed every time. My appointments are always on time, no waiting around in the waiting room for extended amounts of time. Parking is validated. Front desk is professional, competent, and friendly. My dental hygienist Jan is awesome!! I’m usually in and out of my appointment very quickly. I highly recommend Dr. Hayashi. There have been a handful of times I’ve had a different hygienist because of schedule, and they’re all great.

I had to switch dentists due to a change in my insurance and my periodontist referred me to Dr Hayashi. After a few visits to Dr Hayashi, I have to say how grateful I am for that referral. Dr Hayashi is so nice and knowledgeable and caring. Going to the dentist is definitely not my favorite thing to do however Dr Hayashi makes it bearable. I think he is a top notch dentist. His assistant is also fantastic and really nice, and my hygienist Annie is the best! His office staff, headed up by Nancy are also the best. He’s also in a great convenient downtown location. I feel well taken care of by Dr Hayashi and his staff.

The dental office of a Mr. Garrett Hayashi is the best thing, dental-wise, that has ever happened to me. I had an awesome dentist who lost his lease and became part of a not-so-awesome practice which inhibited his skills and value, then I had an overpriced dentist who charged me an arm and a leg and a baby’s bottom for everything. Everything. Who has to pay $100 for a cleaning covered completely by insurance? Suckers. Like I used to be. Enter my eldest brother who speaks worlds of his dentist, Dr. Hayashi, and a sudden, impulsive desperation to whiten my teeth. Next thing I know I am being examined, photographed, x-rayed, and then given a clearly explained treatment plan by a dentist who seems like he would just love to spend all day answering my questions. Impressed. Front desk Cori? Wonderful. I love her. She also makes cakes. Amazing, amazing cakes. If you need a jaw-dropping, gorgeous cake, go to none other than Cori at Dr. Hayashi’s. Unrelated yet related. After hearing my treatment plan I was expecting to be quoted, literally, $10,000. Or near that. My actual quote was far less which makes my previous dentist seem even more overpriced. He was a good dentist (his partner not so much), just so very expensive. Dental assistant? INCREDIBLE. I opted for the in-house whitening procedure, set an appointment, came in for the appointment, and she actually talked me out of it and into at-home whitening for HALF THE PRICE because it would yield better results. Wow, I say, wow. No one cared that I had booked a two hour time slot, no one cared about the profit loss, everyone cared about me. That is special. The real test comes in a few weeks when it is time to numb me. Dentists have a very difficult time numbing me. As I’ve mentioned in another review, my oral surgeon never did completely numb me for my wisdom tooth extractions and it was one of the most excruciating experiences of my life. Floats up near pushing human beings out of my private place. This review is becoming very strange… Suffice to say, I am confident my numbing experience will be fantastic and I will stay with Dr. Hayashi for the rest of my life. Unless I move. But then I could visit to see him, so I stand by the first statement. But amend it to the rest of his life as I plan to live until I’m 110 and he is older than me. That’s not morbid, it’s factual. I’m going to stop writing. Dr. Hayashi rocks.

I’ve always felt neutral about dentists (glad it’s never been negative) but with Dr. Hayashi I feel extra positive. Not only is the entire staff in his office courteous and professional, but they keep an extremely clean and efficient running office. I never feel like I’m wasting time while sitting on the chair. But probably the best part is when I see my dental claims paperwork weeks after my visit. I’ve gone through a graft surgery with a periodontal specialist that Dr. Hayashi referred me to (his name is Dr. Umaki and also a great dentist — I’ve written a separate review for him). Both Dr. Hayashi and Dr. Umaki have tag teamed my recovery stage, giving me routine post surgery checkups and teeth cleaning. It made me worry initially that there are so many post surgery appointments, but I’m glad that they’re all part of the surgery service at no extra cost. In fact, I see that my insurance only covers a portion of the bill (albeit the majority of it) and that there are some costs that I’m supposed to pay out of pocket. But Dr. Hayashi’s office did not bill me for those costs uncovered by my insurance and that’s a sign of just doctors caring for patients, not about squeezing every penny they can out of patients.

Still love Dr. Hayashi and staff, even if I haven’t been under their care for a few years now! Miss you all. If you live in Honolulu, become a patient! While I haven’t been to the office in a number of years, I referred my cousin there a few years back, and every 6 months she gives me a summary of her bi-annual visit and the reviews remain glowing. Plus, she always ends up talking about me and my dog Trek with Dr. Hayashi. Thanks for the years of friendly, warm, professional, and top-notch dental work! And for taking care of my cousin’s smile! Still smiling here in California 🙂

I’m not typically a fan of dentists for most of the same reasons that the rest of you all out there are… However, after my first visit here from a recommendation from a friend, I’m glad that I’ve chosen to make this spot the place I go to for all of my dental needs! The staff are overall great and pleasant which makes office visits less anxious and nerve wracking. Dr. Hayashi himself is also a great pleasure too and does a great job of ensuring that you have a great white & straight smile without making the experience uncomfortable. He really cares for your teeth and gives great advice which is always appreciated. His dental assistants are also awesome and do a great job of sending people home with a great smile and shiny teeth too. Need a dentist? Come here and book an appointment with Dr. Hayashi and his staff, you won’t be disappointed!

After a long absence of not visiting a dentist and my old dentist passing away I needed to look for a new one. My girl referred me to her dentist and so I checked it out. Yeah he’s in downtown and rent is probably a grip so I expected to pay up the okole. After my first xrays and consultation he said I needed to fill my cavities before it gets worse and needed a root canal. I finally went in and first thing he does that scares the crap out of me is giving me a shot. The great thing was this was the first time I DIDN’T FEEL IT! I though it was a myth but man I was glad he did it. He fixed my teeth and I was out the door. I was pissed that my mouth was numb but its always better than having pain. Next time I’m eating before I see the dentist just in case.

Dr. Hayashi and his staff were amazing! By far the best dentist experience I have ever had. If you need any dental work in Oahu I would recommend him and his team. The personalized care and follow up by Dr. Hayashi himself was unlike anything I have experienced with any other dentist in my life.
