Laurie is a truly unique, totally awesome, caring assistant that always makes you feel as though you are the most important person in the world, and she helps immensely in making sure you are relaxed, and worry free at all times. Dr. Hahn is really, really into what he does. I never feel like a number, and I always feel as though he wants to make sure that I am satisfied with the results, and I am involved in the process to as deep a level as I care to be. I can ask him any question about his determinations and he will sit down and discuss it and has even on occasion taken my opinion into consideration for my care plan. I have never had that kind of involvement in my care plan before. It has always been dictated to me, and if I disagreed, I did not feel welcome anymore. If you are not satisfied with your Dentist, and you feel like you are just a money making opportunity for their office, then you owe it to yourself, your wallet, your health, and your peace of mind to contact Dr. Hahn’s office and receive the greatest dental care you have ever received in your life!

I think both dr Hahn and Dr Tassey are good and I really really like the hygienists but the two front office ladies are awful. They literally won’t crack a smile, say thank you, or greet you. When explaining why my cleaning was more expensive, the front lady rudely said “well didn’t Dr Hahn look at your teeth too? That’s an extra $50.” The front office ladies really put a bad taste in my mouth which is disappointing because I think the hygienist and doctors are good 🙂

I was never a fan of dentists growing up.
But Dr. David Hahn was super nice and professional. His office was equipped with the nicest machines I’ve ever seen and the receptionist Joanne was as nice as can be!! 10 star experience and im recommending him to my family and friends for sure… Hope this review helps my fellow Yelpers

My best dental experience without a close second.  Dr. Hahn and his team do an exceptional job.  I’m a difficult patient and not a fan of dentists, but Dr. Hahn completely put me at ease and with ZERO UPSELL.  This office does only what is necessary and the work is fantastic.  Modern office with the newest technology and the team explains everything.  Last visit, I had a filling during a morning appointment.  I didn’t feel a thing, and Dr. Hahn even reversed the numbing so I could immediately return to work.  You won’t regret going to this office.

Dr Hahn and his staff are truly caring people who seek to understand their patients needs and go out of their way for you. I first came to his office as I was experiencing a lot of pain in my mouth.  I was at work and did a google search for dentists in Irvine that were close to my office by chance that I could call one and get an appt asap (as it was about 3 or 4pm at the time – and on a FRIDAY! )  I called one dentist and they couldnt see me for 3-4 days and I knew I couldn’t wait that long because I was in too much pain.  I then called Dr Hahns office and after explaining my situation, they asked if I could get to their office in the next 10 min and of course I said yes!  So, first good sign -sympathetic and flexible staff!

Rob D. from Costa Mesa, CA (Source: Yelp)


Dr. Hahn is the best dentist I have ever been to.  His staff are kind, professional and very attentive.  His offices are brand, sparkling new with the very latest technology.  My initial exam included video pictures of each tooth so that I could see exactly what the Dr. was referring to.  He is very knowledgable, careful, thorough and conscientious.  I was with a very good HMO dentist in Newport Beach, but was referred to Dr. Hahn, and now I am actually paying less with PPO for a more modern and well-equipped office!

Dr Hahn and his staff are wonderful. I have had extensive work done on my teeth due to medical issues and Dr Hahn has been there to walk me through every step of each procedure with such care and professionalism. I so very much appreciate each of them.

Randall G. from Costa Mesa, CA (Source: Yelp)


He is that good. He is the type of dentist who gives you his cell phone number on his answering machine. I HATE the dentist, but he makes it bearable. I can not recommend him enough.

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


Dr.Hahn is the best in his field he takes the time to explain procedures as well as treatment options,while giving the very best in dental care.I would highly recommend D.r Hahn if you are searching for a quality dentist.

Dr. Hahn fixed my smile with amazing results. He really changed my life! Before he fixed my teeth, I had what people told me was a “western smile”, meaning I had large gaps between my teeth. When I was a teenager, I asked about getting braces. However, the dentist said the problem was my teeth were straight but they were spaced far apart and braces would actually make my teeth crooked by bringing the bottoms of my teeth closer together while the roots stayed where they were! This resulted in me being shy to smile because I thought my teeth were ugly and definitely made me lack confidence in my looks. However, Dr. Hahn assured me the process would be simple, painless and would give me a beautiful smile – and he was right! He was extremely professional, courteous and calming, which was greatly appreciated as I’ve never been a big fan of dentists and would get rather anxious whenever I had to go to one. The whole process was also much faster than I imagined. My “new teeth” matched the color of real teeth perfectly and look real. It’s been 5 years now and ever since Dr. Hahn, I’ve confidently smiled ear to ear when it’s picture time, and I highly recommend his services to others.

Dr. Hahn is a great dentist and everyone at this office is great – from the front desk to the dental hygienist to the dental assistants.  I’ve gotten my teeth cleaned twice by Tracy and she is amazing.  My teeth feel much cleaner and I feel she cleans cleaner than other hygienists I’ve visited before.  She is super friendly and always tells you what she is doing so nothing is a surprise. The office is very modern and high-tech and his equipment seems very cutting edge.  Every room has a big screen tv where you can see snapshots of your teeth.  Dr. Hahn is very gentle and is always smiling and does a great job of answering all your questions.  Great dentist!

Dr Hahn and his staff are amazing! They are so friendly and accommodating! There office is very simple and up on all the new technology! I love going to the dentist to get my teeth cleaned and the dental hygienist Helen is AMAZING!!! I recommend Dr Hahn to everyone!!

Carrie U. from San Juan Capistrano, CA (Source: Yelp)


I have been going here for a few years based on the other Yelper’s reviews and have had nothing but a good experience. Their entire staff is professional and intelligent. What I like the most is how they explain the procedure you need done 100% thoroughly with pictures! They also work to make sure you are as comfortable as possible (you can get shades and a blankie while they work).

Suzie G. from Irvine, CA (Source: Yelp)


If you need a great dentist, look no further! Dr Hahn is the best dentist I’ve ever been to. The office staff is wonderful and  the office comfortable. I’ve been 3 times and each time the wait time was seriously less than 2 minutes. Dr Hahn is great about explaining everything and has a pleasant bedside manner. My entire family has switched and is now seeing him.

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


My wife and I have been happy patients of Dr. David Hahn for more than five years. Dr. Hahn is an outstanding dentist, very knowledgeable and experienced whom we trust. He does a great job in gentle but confident way using cutting edge technology. He maintains modern and very clean office, equipped with state of the art instruments, all computerized. Exams, prophylactics, fillings, crowns and implants, everything he has done serves well for us. We greatly appreciate this.

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


Update, November 2015: The office recently changed their structure and has one hygienist cleaning now instead of a few. She’s friendly and explains everything she’s doing. The atmosphere is a lot more friendly now and I’d recommend anyone to go here now. I have been going here for several years and was overall impressed with the service I received. However, over the last year I’ve been less than impressed. It started with having one girl be so agressive with cleaning my teeth that I’d leave the office in pain. More recently, a new girl cleaned my teeth and left about a quarter of my teeth unpolished and sent me on my way. It’s quite unfortunate to receive service like this especially when paying so much money to see the dentist. I will be looking for a new dentist now.

My dad had implant crowns done by Dr. Hahn about 6 years ago.  My dad is a fussy guy but he had no complaints about treatment done by Dr. Hahn.  The crowns are still fine.  I would not hesitate in getting dental treatment from Dr. Hahn.  He is meticulous in work and demeanor.

Soo K. from Torrance, CA (Source: Yelp)


Dr. Hahn is so worried about being gentle.  This is a newer office but is fairly busy.  They have this little computerized anesthetic injector so you can’t even feel the pressure of the needle.  I’m a tough girl so I’m used to not having topical and just getting a big syringeful of whatever -caine they use to numb me up.  But, no Dr. Hahn is just too caring to do that.  He’s also into using the best materials, the best lab, and very meticulous with his work.  He is the only dentist in his office so you’ll always be greeted with the same doctor, unlike those dental groups. I had my first cleaning in a year done by him, two crowns, and he replaced some old fillings while I had a new cavity.

Mia L. from Irvine, CA (Source: Yelp)


My husband started seeing Dr Hahn and convinced my daughters and I to go see him.  I resisted at first since I was content with our current dentist.   I have seen alot of dentists in my life and Dr Hahn is top notch – he is a perfectionist. Needless to say, we all switched over to Dr Hahn and he has been our family dentist for the past 5 years and we love him!  His staff is also the best, so very thorough and very professional!

Julia O. from Irvine, CA (Source: Yelp)


I have many dental problems over the years and have changed dentists several times.  I am horrified by each dental visit until I found Dr. Hahn.  His service and skills are really superior. Well, his qualification of being a prosthodontics says itself.  His office is very comfortable with state of the art equipments better than any offices i have been to.  Appointments are very punctual and efficient. He gets complicated operations done in a very short time – at least 1/3 less time compared to other dentists, and much less pain and stress. Everything in his office is first class. His staff are super nice and friendly. Bonnie the receptionist even babysits for me while I was with the doctor.  The hygenist is better than any others. Dr. Hahn is definitely a maticulous doctor who is the best of the best.

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


Dr. Hahn and his staff are awesome!  He does a very thorough job and is very meticulous with his care.  His assistant Lori is such a sweet and nice girl – always very chatty and friendly. I had my 6-mo cleaning done today by his hygienist, Helen, and it was probably the most thorough cleaning I’ve ever had.  The lady at the front is also very sweet and is great about staying in communication with appointments. The office is very clean and makes you feel comfortable about getting treated there.

Dr. Hahn is thee best. My roommate referred me to him and I’ve been going to him ever since (even after I’ve moved to San Francisco) ! He’s very gentle. I had a root canal and honestly did not feel a thing. Not to mention he’s got the latest gadgets to ensure a painless pleasant visit. Thanks Hahn!
