Dr. Harb has been the only dentist I have felt comfortable with letting a dentist do fillings on me without numbing. With having some serious dental anxiety from past experiences with mean inconsiderate dentists from childhood to adulthood….Dr. Harb took all that away! Her chair side manner with me was incredible. Her welcoming smile and attention to detail were all it took. Dr. Harb’s office makes you feel like family from the moment you walk in the door. I highly recommend Dr. Guitta Harb for anyone looking for a dentist in the south Orange County area! If you want a compassionate dentist, friendly staff, being treated with respect and honesty, and a state of the art office you should check her out!

Dr. Harb does a great job all around and ensures that her work reflects her great reviews. Her attention to detail is implacable and she ensures that the needs of her clients are nothing but perfect. The entire office staff is friendly and knowledgeable. Jessica, the dental assistant exemplifies everything about the suburb customer satisfaction and is always welcoming you with a big smile. Thank you for all that you do and I will be seeing you soon.

Dr. Harb has been my dentist for over 7 years! I would not trust anyone else to touch my teeth She is professional, honest, and knows what she’s doing. I have recommended many friends to her and until this day they thank me for referring them. I’m also a big baby and somehow she manages to cause me very little to no pain. Thank you, Dr. Harb! I will be seeing you for my cleaning very soon!

I came back to see Dr. Harb again to do my veneers. I needed to fix my front teeth. She did an amazing job. Before she did the veneers she made me a model to show me what they would look like. They came out exactly as promised. I was so happy with the results and the process was pain-free considering I’m very anxious in the dental chair.  Dr. Harb always makes me feel comfortable.

By far the best dentist I’ve ever been to! I called them for a dental emergency and they had me in the office the same day. Ever since then, every cleaning and cavity I’ve had has been quickly and painlessly taken care of by them. Beautiful and clean office with the best service!

Lara D. from Dana Point, CA (Source: Yelp)


I absolutely must write a review for Dr Guitta Harb after what she has done for me!! I have had the same crowns for about 20 years and they weren’t pretty. I was very self-conscious of my smile and when I’d laugh, I would always cover my mouth with my hand.  Finally, I went in to see Dr Harb. She explained in detail what we could do and how she would be able to give me the smile I’d always wanted.
Today, I have a smile that I only thought movie stars could have!!  Never again will I cover my mouth when laughing – in fact, I now just laugh harder and smile even bigger!!! Thank you from the bottom of my heart Dr Harb!!!!

Carter J. from Aliso Viejo, CA (Source: Yelp)


I had a toothache on Friday afternoon. I didn’t want to go back to my old dentist. I looked up dentists nearby and found Dr. Harb. Her staff squeezed me into her schedule right away. Dr. Harb was extremely sweet and caring. You can tell her Priority was to get me out of pain. They took X-rays and figured out what was the problem. I had a crack in my tooth and it needed a crown. She was able to do the crown for me and get me out of pain. I was very happy especially since it was the weekend and didn’t want to spend it on pain. Thank you Dr. Harb and staff for your care. I’m very happy to have found a great dentist.

Dr. Harb is so nice! I scheduled last minute and they were able to accommodate me right away. The location was easy to get to, the office was clean, and the staff were very friendly. My cleaning was quick and painless. I did have a cavity and she took care of it right then. Overall I’d say it was a good trip to the dentist and I’ll for sure be back here in 6 months.

Dr Harb and staff are all very friendly and attentive. Every visit has been a good experience. Dr Harb really cares that her patients do have a good experience and are well taken care of. Try and see for yourself, you’ll be glad you did! I highly recommend Dr Harb.

Dr. Harb is such a sweetheart. She always makes me feel comfortable when I walk in her office. Cleanings are no fun but she makes every experience as comfortable as possible. She takes her time to explain every one of my concerns and always makes it a priority to perfect your smile. Love this office and will continue going to her forever!

Gina B. from Aliso Viejo, CA (Source: Yelp)


I am a very picky person and so I did my research before finding Dr. Guitta Harb. I needed veneers on all my front teeth and after looking, asking around and researching I found Dr. Harb. She is extremely detail-oriented and is a perfectionist in every way. She did my front veneers and several crowns that look and feel amazing.  Before she did my veneers she showed me what they would look like and went over all the details as far as shape and color. The process was easy and painless.  She is very honest, friendly and trustworthy.  The staff are all very sweet and accommodating.  the office is always very clean which puts me at ease. I feel like I stepped into a spa every time I am in her dental chair. She makes coming to the dentist enjoyable.

Rebecca H. from Aliso Viejo, CA (Source: Yelp)


Always a great experience here! Dr. Harb and staff are super friendly and always making sure I’m comfortable! I always dreaded a cavity but she makes the filling super quick and painless! Totally recommend her and this office!

Diala H. from Aliso Viejo, CA (Source: Yelp)


I went To Dr. Guitta Harb because I was experiencing severe sensitivity on my teeth. I was not able to eat anything cold such as ice cream or enjoy any cold beverage for years. Even breathing in cold air was painful. My previous dentist said everything was fine and was not able to make it better. Dr. Harb was able to bond my teeth and fix them with a simple procedure. My sensitivity is now all gone and I’m able to eat whatever I want. My teeth feel great and I’m so happy to have found Dr. Harb. She’s extremely gentle and is constantly asking if I’m ok in the chair. The office is always very clean and the staff is great. You can tell that the patient’s comfort is her first priority. She’s very thorough with her exams and really takes the time to explain everything. She offers aromatherapy pillow with lavender scent, iPad with headphones and music and a blanket. I felt like I was at home. I was extremely comfortable in her chair. I would highly recommend her. She deserves 5 stars.

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


I came to Dr Harb for a broken tooth. I was impressed by her office, her staff and her work.  Everyone was extremely nice. Dr Harb explained everything in detail. She took care of my tooth and did my crown.. it was a quick appointment, pain-free and easy.  I’ll definitely be back for the rest of my work and I highly recommend Dr Harb to anyone looking for a great dentist.

George A. from Vancouver, WA (Source: Yelp)


I am in town on vacation for two weeks. Before my trip, my front tooth had chipped. I needed to fix it because it was very noticeable and uncomfortable. I called three offices, here they were able to squeeze me in the following day. Not much waiting time when I arrived. I saw Dr. Harb. I got the chip fixed but she also addressed an exposed tooth that my dentist never brought up. I could feel the gap on that tooth but never really thought much about it. I have to say the final result on both teeth actually looks wonderful, I am very satisfied. Friendly dentist and staff. Relaxed atmosphere. I’m very glad I was able to take care of it on the trip and it looks great. 5 stars for me!

We love it here ! Dr. Harb is wonderful, tender and kind . My kids love going to the dentist!

Anthony Y. from Aliso Viejo, CA (Source: Yelp)


Dr Harb has been my dentist for the last 6 years. My wife and two kids see her as well. She has done a few crowns on me and fillings. Her work is always impeccable. She is very gentle, fast and extremely honest. She takes very good care of her patients and she’s very thoughtful and considerate. She always works with our budget. The office staff is fantastic, very professional, helpful and very friendly. The office location is very convenient in the town center plaza.  I would highly recommend Dr. Harb to anyone looking for a great honest dentist.

Highly Recommended! This was hands down the best experience I’ve had in a dentist office. Clean, comfortable and quick service! It had been a while since I had seen a dentist and decided it was about time I’d do a checkup. Dr. Harb was so kind and thorough. A deep cleaning and some composite fillings were required. She made me feel at ease and the treatments were pain-free. She truly cares and is passionate about what she does. I highly recommend Dr. Harb for your dental care. I won’t go anywhere else.

Janet Y. from Aliso Viejo, CA (Source: Yelp)


I have to say that I had a major dental phobia since I was a child. I came to Dr. Harb cause I heard she was extremely gentle and does great work. I had high expectations before I stepped foot in her office. The second I walked in the staff was extremely friendly and helpful. After meeting Dr. Harb I felt so much more at ease. Needless to say, I had a lot of dental work that needed to be done since I was avoiding the dentist for a long time. Dr. Harb put a plan together for me. They went over all my insurance benefits and explained tooth by tooth the cost. They really do their homework with insurances and she didn’t do any work on me without me knowing exactly what the process was and how much it cost. She did a few crowns and few fillings on me and it was so painless. She kept asking me if I was ok the whole time and gave me breaks. She was very gentle and very caring. I love my new smile and I’m happy to say I found my dentist.

Thank you Dr. Harb for always making me feel comfortable and not actually at the dentist. I love Dr. Harb, she gives her medical recommendations but doesn’t try to gouge you with all kinds of fees. She never makes me feel obligated but always cares for me and even my son who is her patient too. She is absolutely amazing and makes me enjoy getting my teeth cleaned. Thank you Dr. Harb for helping to give me a beautiful smile that I can be proud of!!!!

I have been going to Dr. Harb for a few years now and her practice is by far the best dental experience I have ever had. Her bedside manner is amazing. I have provided them a few referrals all they all feel the same. Great staff too!!!

Leena N. (Source: Zocdoc)


I was long overdue to be seen by a dentist and scheduled an appointment with Dr. Harb. The front office was super helpful and explained everything to expect during my appointment. Dr. Harb was very nice and thorough during my exam and cleaning. Sherry her treatment coordinator came in and talked to me about a crown I needed done and explained my options with my insurance benefits. She scheduled my appointment and was so professional and organized. I would definitely recommended this office to my family and friends! Great doctor and team!

Andy H. from Aliso Viejo, CA (Source: Yelp)


Dr. Harb has been my dentist for years now. She is always very professional and has a great bedside manner. She really cares about her patients and it shows in her work. Her staff is very welcoming and friendly. She takes her time with her patients and puts in 100%. My whole family comes here and they are extremely happy with her. I recommend her to anyone looking for quality dentistry.

Yvonne S. from Aliso Viejo, CA (Source: Yelp)


I would recommend Dr. Harb to anyone!  She is a great dentist and most importantly very gentle!!!  I don’t think anyone enjoys going to the dentist but its definitely easier to visit this office.  It is always clean, flat-screen TVs at the chairs and the staff is friendly.  I also like that she asks about my kids and my life, she is social yet professional.  They are also very good about getting you in if there is an emergency dental issue.  If you’re looking for a dentist, Dr. Harb is the one to see!

Craig B. from Ladera Ranch, CA (Source: Yelp)


Excellent Dentist. Dr. Harb is very aware of her patient’s needs and makes them feel very comfortable.

I highly recommend Dr. Harb!!!   She is super sweet, professional, caring, and always greets you with a smile.  My husband and I were so lucky to find her as our new dentist when I moved here to Aliso Viejo 5 years ago.  Her staff is friendly, her office is very clean and she uses all the latest dental technologies!  She has done lots of work on my mouth and keeps my teeth looking super shiny and clean!  I would highly recommend Dr. Harb as your dentist!!!

Gus H. from Aliso Viejo, CA (Source: Yelp)


I came to Dr Harb and had my implants and crowns done here. Dr. Harb did an amazing job. She was extremely gentle, she explained everything in detail before doing anything. The procedure was painless and quick. I have my crowns in now and they look amazing. Her prices were very reasonable. Not to mention the staff was very helpful and nice. They really cater to their patients. The office is very clean. Love coming here. Would recommend her for sure.

Dr. Guitta Harb is by far the best dentist that I have ever met! I have always been terrified of any dr working on my teeth because my teeth are super sensitive. She made sure I felt comfortable and was in no pain and talked me through everything she was doing. I highly recommend Dr. Guitta Harb.

Todd H. (Source: Zocdoc)


Going to the dentist is never fun but Dr. Harb and her staff are a pleasure to work with. I’ve used the same dentist for over 20 years. So after moving to the area over a year ago I was skeptical I would find a suitable dentist so quickly. Dr Harb’s practice made the transition frictionless. So far I’ve used Dr Harb a few times for regular teeth cleaning and standard fillings.

Megan C. from San Clemente, CA (Source: Yelp)


Working with dentists can be stressful in many ways. With Dr. Harb, she took all that away! First, Dr. Harb’s office is beautiful and has state of the art equipment so you know you’re getting the best possible experience. Secondly, Dr. Harb herself was absolutely amazing. Her chair side manner is so gentle and caring. She listens to every concern and is very thorough in explaining what work needs to be done. Her staff was extremely helpful in working with me from scheduling to working through financials. I am so grateful to have found an office that made me feel so comfortable and would highly recommend Dr. Harb if you are looking for a dentist.

Keeley B. from Aliso Viejo, CA (Source: Yelp)


Dr. Harb is the best! I have been to her for my teeth cleanings, bondings, fillings, and always get extra advice and help on how to better take care of my mouth. She is very gentle and does her job exceptionally well! She has a very upbeat personality and is so sweet, which made me a lot more comfortable sitting in her chair than previous dentists I have been to.
Her office is VERY clean and spacious and she offers water and coffee for her patients. The girls who work the front desk are very friendly and always smiling as well, which sets the tone for any patient to have work done. The cost has been very reasonable and she also offers payment plans for some of the major services she offers.
Dr. Harb is now my regular dentist and I am so lucky to of found her! I would recommend her to anyone in a second!

Tom H. from Aliso Viejo, CA (Source: Yelp)


(…)  I have been to 3 other dentists in the last 2 years and have been very disappointed with quality and service. However, Dr. Harb set the bar high. She is extremely gentle and caring and very sweet. You can tell she takes pride in her work. Never a wait to see her. Her staff is always friendly. She is very detailed oriented and really takes the time to show you everything. Her prices are average for the area but the quality is the best.  I got to watch movies and relax while she was working on me. I am glad I finally found the right dentist.

V. G. from Silverado, CA (Source: Yelp)


Dr. Harb is very gentle in treating her patients. She explained to me the complete treatment before it started. She also does implants and she provided guidance in how it works. During the appointment, she dedicates her complete attention to you. She is very professional and works with your schedule. I am happy that I chose Dr. Harb for my treatment.

Bill G. from Laguna Woods, CA (Source: Yelp)


(…) Dr Harb systematically went over every tooth in my mouth and told me the condition of each and what work needed to be done according to priority. She then gave me an accurate cost estimate on each tooth. It was good for me to know this before getting into the work so I could plan and budget for it.
I went ahead and opted for two crowns which I really needed. She did the prep work painlessly and quickly. Today I got fitted for the two crowns and they fit perfectly with an exact color match. I’m very happy with Dr Harb and would highly recommend her for friends, family or anyone looking for an expert dentist at a reasonable cost.
