This office is clean and beautiful. They have all the latest tools and gadgets. I’ve been coming here for a few years and the team is consistently great. I’m always seen right away. I also really appreciate how they treat me. Always smiling and so welcoming. Like everyone else, I don’t love going to the dentist, but this group makes it such an easy and efficient process. I know I’m in good hands and I really like that Dr. Smith takes the time to talk to me about what she’s seeing and how I’m doing health-wise and just in general. They treat me like a person and not just a mouth full of teeth. 🙂 So grateful for the team at The Dental Office on Red Hill!

I can’t say enough great things about The Dental Office on Red Hill.  Nicole is my dentist and all of the hygienists and staff in the office are amazing.  I am always greeted with a friendly familiar face and am made to feel welcome from the second I walk in to the second I leave.  They are very clean and organized and keep financial concerns in mind offering multiple options for effective treatment and maintenance.  I have had poor experiences in the past with previous dentists that I have seen, feeling like they just wanted more money from me every time I came in, recommending the most expensive treatment/care options and nothing else.  I like that Nicole and her team offer multiple choices and recommendations that work well with my lifestyle and budget.  They also have personalized tvs in every room so you can watch whatever you would like while you get your teeth cleaned.

I never knew I could like going to the dentist so much.   I would recommend this office to everyone!

This office and Dr. Smith are awesome. 1. The office is clean, modern and has the state-of-the-art technology. 2. You get your own TV while your services are being done. 3. Dr. Smith is informative, gentle and has great bed side manners and makes my teeth look fabulous and even (she fixed some grinding angles on my teeth and my smiles looks soooo much better.) 4. I love that the hygienist cares about your teeth too and gives tips on how to get the trouble spots better.

Dr. Smith and the amazing staff at The Dental Office on Red Hill are the absolute best in OC. Each incredibly friendly and knowledgeable in their areas of expertise and then some – everyone from the front desk staff, the assistants to the Doctors – experience top notch service and dental care at The Dental Office on Red Hill. Dental care made easy – and affordable! Do yourself a favor – go see Dr. Smith!

L A. from Irvine, CA (Source: Yelp)


I love this dental office! Liesel gives the best cleanings I have EVER gotten and is always so lovely to talk to. Dr. Smith, the owner, is very knowledgeable and always provides me with such great information and top-notch care. The entire team is very professional but also personable and I know that I’m in good hands with their clinical recommendations!!

Steve R. from Tustin, CA (Source: Yelp)


Dr. Nicole Smith is probably the best dentist that I’ve ever been to … no really!  She is a person who loves dentistry and loves helping people … she’s a perfect combination for anyone that needs a kind, caring, and capable dentist.  And she’s fully supported with other kind, caring, and capable people who are her staff and ‘office family’.  Most of us wouldn’t look forward to going to ‘the dentist’; but my wife and I both always look forward to seeing “Dr. Nicole” at The Dentist Office at Red Hill.

Jas R. from Riverside, CA (Source: Yelp)


We are new patients of this office, and our first visit was really great! Their schedules are very flexible, the office looks nice and clean, the staff who were there at that time, Jessica and Roel, were very professional and super nice and always attends to your needs. Dr. Smith, our new dental physician is very good and professional! Did my Cerec crown really fast and perfect. Me and my husband are so glad to have found the perfect dental office for us.

Erin B. from Irvine, CA (Source: Yelp)


Called at the end of December 2017 and they got me in before year end. I’m a new patient to Nicole Smith, DDS. Great overall experience. Office staff there works as a team to get you in and out without wasting time! Lea, the hygienist was accommodating and so gentle, no discomfort, no pain, no bleeding during the cleaning and she’s super nice too! I LOVE this place and I usually dread going to any dentist!!

Sara M. from Irvine, CA (Source: Yelp)


The Dental Office on Red Hill has done an excellent job with all of my recent needs for a new retainer, mouth guard and bleaching trays. It seems as though I’ve visited the office more than a handful of times this year so far, and have seen a huge improvement with customer service and Dr. care since my visits last year. I am appreciative for their attentiveness and great communication! For me, the best part is that their office is always up to date with the latest in technology and dentistry.

Sean S. from Redlands, CA (Source: Yelp)


I’m so in love with this dental office and everyone there! As someone who literally hated the dentist and went about once every 10 years, it’s amazing that I know look forward to my appointments and having a cleaner smile!

First off, Dr. Smith is where it’s at. She has the best chair-side manor of any doc ever. I feel confident in what she’s doing and I trust her advice to improve my oral health.

Yesterday I finally bit the bullet (no pun intended) and went in to get my broken molar fixed. This thing was majorly jacked up from my car accident, and has been a constant bother for over a year. In just ONE and A HALF HOURS, I had a perfectly milled and fitted onlay crown, and was happily strolling out the door; some residual drooling aside.

The RDA Angie who took care of me was awesome! She made sure to put the game on the flat screen and give me headphones so I could zone out while all the drilling was going down.

I should also mention that the Manager Xavier is legit. He always explains everything super simply and makes sure I understand any costs before hand.

You will NEVER find a better dentist that The Dental Office On Red Hill.

Sabrina G. from Los Alamitos, CA (Source: Yelp)


This Dental Office is Awesome!

let me just say that, I am one of those people that only goes to the dentist when something breaks or hurts.

I was due for a cleaning (I’ts been 6 years) and finally decided to get one. The Hygienist was awesome! My teeth are cleaner than ever before and my deep cleaning didn’t hurt one bit.

The office and staff are extremely nice and helpful. I was refereed here by a few individuals that have been seen in this office and everyone  had nothing but good things to say about this office and staff.

Josh K. from San Luis Obispo, CA (Source: Yelp)


Great office. All of the equipment is new, clean, and the highest level of technology.

I really liked how the X-ray room is setup so you can see the x-rays as they are being taken. They also have TVs in the cleaning rooms, so you can zone out while they clean your teeth.

$59 check-up/cleaning was fantastic. It did wind up a little more because I had some deeper cleaning – that’s fine, I came to make sure my teeth would be healthy.  Dr. Smith was very instructive and professional. I walked in here because it was close to my office, but will definitely return for my routine oral care.

Corey M. from Costa Mesa, CA (Source: Yelp)


I can’t say how THANKFUL I am to have found such a wonderful dentist in the Irvine area! Dr. Nicole Smith is an absolute rockstar! She’s got an amazing bedside manner and her cosmetic dentistry results speak for themselves! The office is ultra modern with TV’S equipped with Direct TV in each chair, it really makes you think why you ever went anywhere else! Go to the Dental Office on Redhill! You’re Welcome!

Lindsay M. from Newport Beach, CA (Source: Yelp)


This office and the team are great!  Dr Nicole Smith is a very professional and experienced dentist.  She and her team make the whole experience comfortable.  The office is brand new, very clean, embraces technology, and makes the overall experience much more positive than your average dental visit.  I’d definitely recommend them to anyone looking for a dentist in Orange County!

Faith E. from Tustin, CA (Source: Yelp)


Moved to the area and had a co-worker recommend this dental office. I loved every second of my experience. After scheduling the appointment I was immediately sent an email to fill out the necessary forms ahead of time. This made my check-in process very easy! I just had to sign a couple of documents and was seen almost immediately. The staff was very nice! The doctor, Dr. Smith, was friendly and very professional.  The office is very modern in it’s technology. They even let you watch TV while they clean your teeth. I’m excited to call Dr. Smith MY dentist. Highly recommend this place!

Mark T. from Irvine, CA (Source: Yelp)


The Dental Office on Red Hill has been my dental provider for many years now. I was happy I made the switch to them years ago, and continue to be happy today.

The staff and dentists have always impressed me with their competency and friendliness.

The office is modern and clean, with the latest technology.

Most of the time the wait time from my arrival to being seen is minimal.

One time when I had an old filling pop out, they got me in right away to have it replaced.  

This place is the best dental practice I have ever had as my dentist.

Kimberly H. from Irvine, CA (Source: Yelp)


They are the best! They are so chill about me constantly rescheduling. My appointments are so quick and easy! And everyone is so friendly! Who knew they can make coming to the dentist fun!

Jonathan G. from San Clemente, CA (Source: Yelp)


I came here for my first time about a week ago. Excellent staff, very friendly and helpful.  The office is very modern and all the work I had was precise and well done.

James H. from Rancho Santa Margarita, CA (Source: Yelp)


I was referred to Dr Smith by a friend. Dr Smith and her staff were very friendly and made me feel super comfortable. Dr Smith really took her time accessing my needs. The hygienist was great as well and made me feel at ease during my cleaning.
I would definitely recommend Dr Smith and her staff to my friends and family.

Dave Braney (Source: Facebook)


Dr. Nicole Smith is wonderful. She is both helpful and caring. This office uses the latest technologies and makes you feel comfortable from the moment you walk through the door. The entire staff is friendly and makes going to the dentist office more pleasant.

Taylor S. from Long Beach, CA (Source: Yelp)


I can’t begin to thank the Dental office on red hill! They are absolutely amazing and so very professional. Thy go above and beyond to make sure all your questions are answered and inform you of everything they will be doing. Dr. Smith is superb and so is Liesel!! Thank you.

Janie P. from Anaheim, CA (Source: Yelp)


After being referred to this office by a colleague, I was very happiness with the entire experience. The online booking for the appointment was very easy. The pre-visit questionnaire I filled out line made the check in process a breeze. I was personally greeted by Dr Smith and she took me back for my consultation. Dr Smith and her entire team were great. I appreciate their thoroughness and the quality of care I received. They made me very comfortable during the entire visit.  I enjoyed having the 3D mouth scan that they used to as a reference while explaining some of my findings. I would definitely recommend this office to others.

There may not be anyone who hates the dentist more than I. But, if the deed has to be done, you have to go. Dr. Nicole Smith is kind, caring and even reminds me to breathe! In all seriousness, she is one of the best I have gone to, The staff is always friendly and polite. I would highly recommend this office and Nicole Smith.

Nicole C. from Irvine, CA (Source: Yelp)


After a bad experience with my previous dentist, I was hesitant to take care of my dental issues, but I knew it had to get done eventually.

My company switched insurance plans this year, so it gave me a good excuse to pick a new dentist. One of my co-workers also switched to this office, and raved about her experience here, so I decided it was time for me to call and make an appointment with Dr. Smith. I was blown away at how friendly the office staff was, and immediately felt like I was in good hands.

They emailed me some electronic forms to fill out before I came in, so it was pretty hassle free when I came in for my first appointment. When I arrived, I was greeted by the lovely ladies at the front desk, and sat in the waiting room for less than 2 minutes when Dr. Smith came to get me.

She walked me back to the X-ray room, gave me a full explanation of what they were going to be doing, and then we reviewed the images together to come up with a treatment plan.  

I was amazed at how thorough Dr. Smith was – She even did a little “head & neck massage” to check for oral cancer. I’ve never had any other dentist do that! They have monitors in all the rooms, and while you’re waiting, you can watch TV. Everything was clean, bright & well kept. They even have coffee/water in the waiting room so you can relax while you wait (if you even have to wait that long!).

I have been back for a couple of appointments since my first visit, and have a few more to go before I’m back on track. I no longer fear going to the dentist – It may be weird to say, but I think I actually enjoy being there!

They’re also very willing to work with you on payment if you can’t come up with the entire balance up front. My last visit was a little pricey, so they were able to bill me half now & half later. That really helped me out!

Everyone in this office, from the dentists, to the hygienists, to the front desk staff are all amazing to work with, and have been extremely friendly & helpful. If you’ve had a bad experience elsewhere, I’d recommend coming here to restore your faith in the dentist. You won’t be disappointed!

Dr. Nicole Smith Is the Best!!! I traveled from Florida to California because my son and several friends in Cali raved about her work! I must say it was well worth the trip! After having several consultations and poor cosmetic dentistry done in Florida I decided to go see Dr. Smith. She was able to give me the PERFECT smile with PERFECT and BEAUTIFUL crowns, all within ONE WEEK!! I can’t say enough about her professionalism, her “bed side manner” and how she made me feel cared for and confidant that I was getting the best treatment out there! I also have to mention her amazing staff- Kari at the front desk, Jessica the office manager and Sylvia who did an amazing job on my whitening !! If your looking for the best Dentist around you should call Dr. Smith !!

John D. from Irvine, CA (Source: Yelp)


I am one of those people that goes to the Dentist every 4 years only because I hate it so much. There isn’t a time I can remember that I actually wanted to go back to the dentist. That’s all changed ever since I came to see Dr. Smith. Her chair side manner makes you feel completely at ease and assured that she’s going to make this as pleasant as possible. The front office staff is also incredibly nice and did everything in their power to let me know how much this would cost and how much was covered by insurance. Overall, I would recommend this dentist to anyone in the OC area looking for an amazing dentist that is professional, caring, and NOT a salesman. I’ve already got 3 of my coworkers to make appointments here as well.

If you’re afraid of the dentist like I was, you have to try this place. I actually already scheduled my next cleaning because of how great this joint is. Can’t recommend them enough!

Got my treatment & actual crown in less than 2 hours! Amazing! Thank you, Dr. Smith, Carrie, Gwen, Xavier & the entire staff!

Anna B. from Lake Elsinore, CA (Source: Yelp)


Just got my permanent crowns cemented! They look awesome and they match the color of my other teeth perfectly!! The only reason it took so long to finally get them was because my crazy busy schedule had me rescheduling a bunch (sorry guys!) Thanks again for making this process so simple and seriously painless!

Amy B. from Costa Mesa, CA (Source: Yelp)


I loved my visit to The Dental Office on Red Hill. Dr. Smith made me feel so comfortable. She would ask throughout the procedure how I was feeling, and if I needed anything. You can tell she loves taking care of teeth, and I felt like I was in great hands. My dental assistant Angie was so sweet. Through all of my X-rays she was very gentle, and made sure I was comfortable every step of the way. I have already booked an appointment for a cleaning in a few months, and I think I’ve found an office for life.

Analisa S. from Long Beach, CA (Source: Yelp)


I loved my experience at The Dental Office on Red Hill. You won’t often hear those words come out of my mouth. Let me start by telling you that I HATE the dentist! But I hadn’t had a check up in over a year after my last Dentist moved to Texas. Dr Smith was wonderful, as well as the assistant Angie. The whole office was friendly and helpful. Dr. Smith gave me great suggestions for teeth sensitivity and did a very through cleaning. I will definitely be back! I found my new dental office “home”.

Sarah B. from Newport Beach (Source: Yelp)


I’ve been going to a different local dentist for years now and never knew how much better it could be until I visited this office!  From the moment I stepped in, every aspect of this visit was warm and welcoming, and I was there to get fillings (not the most pleasant experience), not just a cleaning, so the fact that I walked away happy was a huge plus!  

The receptionist, Kerry, welcomed me with a warm smile and was very sweet and informative while going through the initial paperwork.  The dentist, Dr. Nicole Smith and her assistant Gwen were very kind and reassuring the entire time.  They were professional and informative without being too clinical which made me feel comfortable that they knew exactly what they were doing and included me in every step of the process.

Throughout the procedure, Dr. Smith let me know how I could improve my dental health, (without judgement) and her calm and friendly demeanor definitely put me at ease.  I’m not a huge Yelp review person, but I found myself wanting to write a positive review even before the visit was done!  

I initially looked into finding a new dentist bc my old one was becoming increasingly expensive, even with my insurance.  But here, their administrator, Xavier, really helped me out by working with my current financial situation so that I could afford the appointment. They explained different options for continuing my dental health plan and I felt very confident moving forward with this office for future visits.  All in all, I would HIGHLY recommend them for anyone who is looking for a better dentist who actually cares about you and your needs.

Patrick S. from Irvine, CA (Source: Yelp)


I had an excellent experience at the Dental Office on Redhill. Dr. Smith was professional, courteous and honest. She makes sure you are completely comfortable. Her technician Angie was also very easy to talk to. I will definitely recommend Dr. Smith to anyone in need of a great dentist.

These guys were awesome, as somebody who doesn’t like going to the dentist, it’s a big deal for me to have a pleasant experience during a visit, which is exactly what I got at The Dental Office on Red Hill. They had a terrific bed side manner and did great work. 5 stars, I’d recommend it to everybody.

Sarah F. from Aliso Viejo, CA (Source: Yelp)


I am very excited to have found this new dental office.
It is very close to work and is easy to get to, right off Red Hill.

The staff was very friendly and kind.  I REALLY like Dr. Smith, she is wonderful!!

The office new, very clean – the equipment is all new technology (I’ve never had xrays done so quickly, and easily!)

They did a great job!!

Jamie U. from Huntington Beach, CA (Source: Yelp)


Staff is so kind and helpful. Dr. Smith is gentle and compassionate and makes sure I’m always comfortable! 5 stars!


I am passionate about providing comprehensive, high quality healthcare to my patients. I am honest and enjoy educating my patients about the care they will receive. My goal is for every patient to leave our office with a happier, healthier smile!
