Dr. Setya and his office staff are second to none. My first visit started with a tour of the office. Everyone, especially Dr. Setya, have the best manners and make you feel like a special guest. All of my appointments were on-time and I received not only a  treatment but also an education on how to care for my oral health. Dr. Setya and the hygienist were very thorough on all treatment. It was an excellent experience for me and I recommend Dr. Setya to all that are looking for a competent and ethical dentist.

Dr Setya & Daniella took great care of me. The doctor fully explained all of the issues around a procedure I am to have in a professional and very friendly manner. I am glad that he & his folks will take care of my issue.

What a wonderful experience today Dr. Setya and staff. Great warm environment –
Often times through referrals and the fact that my own family is in dentristy it is common to feel anxious. All of my fears put to rest. Dr. Setya will be performing an implant and I feel as if I am in my own brothers hands. A wonderful peace indeed. See you soon Dr Setya as we begin this journey together I am confident I am in the right hands for my procedure.

Dr. Setya and his staff are professional, compassionate, and know how to assure a healthy mouth which is related to over all good health I put off making an appointment for a year and a half. Thankfully Dr. Setya and Laurie have enabled me to restore bone loss and save a tooth. Please, don’t put off making your appointment. The sooner your treatment begins the better chance you have for having a healthy mouth and over all better health!

Very friendly and professional environment. The entire  procedure was done efficiently with minimal pain . Entire staff made me feel very comfortable.  The  recovery was quick .I would highly recommend Dr. Ajay Setya for any periodontist treatments.  He and his staff are the best, top notch !

Tim J. from Capistrano Beach, CA (Source: Yelp)


Dr Hirst is kind and thorough.   He kept me informed about everything and explained each process.   Almost painless procedures!!  I was referred to this office by my primary dentist.    Their team is there to make you feel comfortable and cared for.   My primary dentist could lose me as a result of this great dental company.

I had an implant placed in my jaw by Dr. Setya. I have had several before from other doctors, I visited other offices in Laguna Niguel and Mission Viejo and was not impressed. My dentist Dr. Mar recommended Dr. Setya and I understand why; he is excellent. The office staff (Robin) and the assistants were fabulous. I was very impressed with the professionalism of the entire team. The preparation, medications, and communication to my medical doctor was great. The pre-op care was clear and easy to do. The surgery was comfortable with no pain, it was actually a lot better than I thought. The post-op and planning of future appointments was excellent. Also, they worked will with my insurance company and I am actually paying less than I thought. If I ever need an implant again? I hope not, but if so, I will definitely go back to Dr. Setya. His team has my full recommendation!

Dr. Setya and his team are wonderful! They were very detailed in their explanation of what needed to be done and what the surgery would entail. They made me feel very comfortable and at ease. At a later appointment, a last minute commitment arose and I had to reschedule my appointment- they were extremely accommodating and let me come in right before they closed, which was incredibly kind. I highly recommend them!

Dori M. from Laguna Niguel, CA (Source: Yelp)


My dentist referred me to Dr. Setya for an evaluation for an implant.  From the first visit to my last, most recent visit (about a year later) Dr. Setya and his staff treated me with compassion, kindness and respect.  He took the time to fully explain every step of the process and answer my questions completely.  I felt like I was in the best of hands with Dr. Setya and trusted him completely.  I highly recommend Dr. Setya

Krystn I. from Trabuco Canyon, CA (Source: Yelp)


Dr. Setya was very helpful and kind with this nervous patient. As a young child I had a very bad bike accident and caused some trauma with my teeth. He settled my nerves through the every step of the way with my dental implant. He made sure I wasn’t in any pain and talked me though the entire process. Thanks again Dr Setya!

Just had a gum grafting surgery. The staff was very informative and made me feel at ease. The office was very nice and clean. Dr setya is amazing at what he does and made the surgery go smooth and easy. I would highly recommend them for any oral surgery.

Devin M. from San Diego, CA (Source: Yelp)


This is now my second time coming in for gun grafting due to gum recession, and both experiences have been painless with very quick and effortless recoveries. I would highly recommend Dr. Setya for any oral surgery! He is not only fabulous at his profession but he is also very personal and kind. Also, the ladies in the office are very accommodating and friendly.

Trey W. from Redondo Beach, CA (Source: Yelp)


One word describes this practice…GREAT!  I recently had a final post-surgical consultation for a procedure performed approximately 2 years ago and the results continue to be amazing!  In addition to the positive results, I can testify to what so many other patients have shared on Yelp.  Dr. Setya possesses an impeccable bedside manner, the office staff like Samantha are all highly professional, and the text message appointment reminders are incredibly helpful!  Thank you again Dr. Setya for a job well done!

Kristin F. from Santa Ana, CA (Source: Yelp)


I don’t know how anyone could say anything negative about Dr. Setya or his staff! He has amazing bedside manor & is extremely personable. They make any procedure as painless as possible, giving you more than enough information to prepare for pre- and post-op. Judy is so caring and engaging as well! I have been going here for almost 5 years and hope I never have to go to another periodontist!

Taylor Jones (Source: Facebook)


The two greatest Periodontists around! Very gentle, knowledgeable and caring. They have the latest technology that makes procedures quick and less painful. Both doctors are great at explaining every procedure to you before and answering your questions thoroughly. The staff is great too! Very friendly, on top of everything, they follow up with you after procedures and provide you with all pre and post operative care you need. I highly recommend this team if you need any periodontal work done, especially implants.

Sanam M. from Aliso Viejo, CA (Source: Yelp)


A HUGE HUGE THANK YOU to Dr Setya and his wonderful staff, Amanda, Michelle and Robin. I was treated with the utmost care and experienced stellar customer service from the minute I walked through the door. I’m so happy I came here. Everyone in the office is so friendly! Amanda greeted me as soon as I walked in. Michelle gave me a tour and assisted dr Setya during the operation. Robin went over pricing and insurance with me. I was referred to Dr Setya after a frustrating experience with another periodontist. I needed a crown lengthening done due to having a fractured tooth, and had booked the procedure with another periodontist 3 weeks ago for today, 8/17. Two days ago the other office called me and said they needed to move my appointment to another week because they double booked me. I was frustrated because I’m a mom of two young girls (1.5 and 3.5) and I work full time. I had already arranged childcare and took the day off of work for this procedure. I wanted to get this over with, and I hate getting work done on my teeth. Just knowing what this procedure would entail gave me anxiety. I was really frustrated when the other office didn’t seem considerate of my situation. My regular dentist then referred me to Dr Setya, who was able to fit me in for today. I thought I was just going for a consult, but it turned out he was actually able to do the procedure on me today! I was overjoyed because today was the day I was originally supposed to have this done. So happy! The procedure went smoothly and much faster than I anticipated. Dr. Setya made sure I was extra numb, as I typically have a hard time getting numb. He asked me how I was doing every couple of minutes. He kept me apprised of his progress and was very reassuring the entire time. I was extremely comfortable in this office and just blown away that they were able to take care of my problem right then and there.

Had an extraction and bone Graff today with Dr hirst. An amazing and wonderful experience. All during the procedure he explained to me what was going on and for a person like me that was essential. Here I am several hours later and I feel great. Thanks dr hirst ad your great staff.

Dr. Setya and Dr. Hirst are outstanding dental professionals. Their skills are at the highest level one could expect and their personal patient care is wonderful. Their office staff and dental assistants reflect the level of excellence that Dr. Setya and Dr. Hirst exhibit. I highly recommend them to anyone who is in need of the finest dental care.

Shirley M. from Laguna Hills, CA (Source: Yelp)


Today was my first visit for a consultation with Dr. Setya. I was impressed from the minute I walked in the door. The office was very nice and the staff was very friendly. I was offered something to drink before being taken back. We stopped at every cubicle and I was told what specialty was done in it. I was introduced to everyone we passed. When Dr. Setya came in I immediately liked him. He discussed in detail everything he was going to be able to do for me and answered all my questions. I’m looking forward to my next visit.

Judy T. from Mission Viejo, CA (Source: Yelp)


Even I work here in this office as a surgical assistant for more than 19 yrs – but what everybody needs to know, I am also a patient too.   A happy patient! I am very proud of our office! Dr. Ajay B. Setya, Dr. Robert C. Hirst, and Dr. Christen S. Bergman are highly trained specialists in all forms of treatment for the gums and bone surrounding teeth and in the placement of dental implants. I know how they work, – I assist them with all kind of procedures, I see their work every day, and I love working with them, and  I feel very safe to be in their hands as a dental patient too. They are California’s top-rated and award-winning periodontist. I am a patient of Dr. Setya who is a highly trained dental implant specialist and has placed thousands of implants, also holds many advanced certifications in dental implantology and is an international lecturer in advanced dental implant procedures. He is also a famous lecturer and trainer to other practitioners across the U.S. and abroad on implant procedures, gum disease, and gum recession treatment.
Dr. Setya is very professional, conscientious and always explains in advance what he will be doing. He always makes sure that his patients are comfortable during the surgery, and it’s good to be his patient. Again, because I work here, I know our staff, they are on top of safety, top on sterilization, and all of my colleagues are very friendly and professional, they will take care of every patient every need from the time they walk in our doors. All of them will work closely with each patient to make sure their appointments are efficient and that they are comfortable at all times. They did take care of me too, so that’s what happened to me. Let me tell you, it’s so weird sitting on the other side of the chair as a patient! But my experience as a surgery patient was excellent! I got my dental implant, first was an extraction with bone graft, then 3 months later a dental implant! Pain-free, very comfortable and my recovery time was very fast! A matter a fact after my Implant surgery I went back to assisting right away! Of course, I have my regular hygiene visit in our office too, every 3 to 4 month I am taking advantage of how lucky I am to see Laurie or Melody They are both excellent RDH – no wonder some of our patients are coming to see them far away after they moved even from out of state just to be in their chair. Please if you have any question about my experience just let me know. Message me 🙂

Dr. Setya and his staff are always kind and looking to help. They will explain in detail each part of your experience before or as it happens— procedure, payment/insurance, follow up, etc. I had a gum graft procedure with them about 4 months ago and everything is progressing as I had hoped.

Today I had my first appointment with Dr. Setya. If I could give 100 stars, I would. Everyone from the front staff to the back staff were exceptional. The Dr is extremely kind and thorough. I am excited he offers minimally invasive procedures and has taken all my worry away!! Thank you to the Dr and staff for making me feel at ease and I look forward to getting the treatment I need!!!

Jen B. from Laguna Hills, CA (Source: Yelp)


I can’t say enough about Dr. Setya and his staff.  I had to have a front tooth extracted and was very nervous about the whole procedure. Dr.  Setya explained everything he would be doing and the nurses took extra time to go over all the instructions and answered all of my questions. Everyone made me feel so comfortable and the procedure went great. The office is very professional and friendly and I would highly recommend Dr. Setya!

Office staff including Robin is always so pleasant and friendly. Melody, the hygienist always takes great care in making sure my teeth are very clean and shiny. Dr Setya is Mr Friendly too. I would highly recommend Dr Setya and his staff for any implant work needed.

Cheri W. from Trabuco Canyon, CA (Source: Yelp)


Referred to Dr. Setya by my dentist over 10 years ago when I needed a dental implant.  The entire process was great from start to finish.  I have been visiting the office once a year since for a maintenance cleaning (in addition to my regular dental cleanings) and my implant is great.  Very nice staff and would recommend highly:)

Denise R. from Trabuco Canyon, CA (Source: Yelp)


Dr Setya is not only an outstanding surgeon he’s a really good person.  From the moment you enter his office his professional staff greets and attends to your needs.  He is always on time and is very empathetic.  I had the experience of having a molar pulled and an implant placed in its place.  At no time was I ever in pain even though I was very nervous about the procedures.  Dr Setya was very calming and direct with me.  I appreciate his skill and bedside manner.  I highly recommend Dr Setya!

This is the dental office you have dreamed of! Have you been wishing for a Periodontist that is at the top of his field, continually educating himself and evolving with the needs of his clientele? Maybe you would like to find a dental office with state of the art equipment all under one roof?

Everyone in the office makes a conscious effort to make you feel welcomed, at ease and taken care of. Every interaction I have experienced has been a positive one that exceeded my expectations. I have had xrays, teeth cleaning, gum grafting and follow up care here.

Philippa C. from San Juan Capistrano, CA (Source: Yelp)


My dentist recommended I get a consultation with Dr. Setya about my on-going dental care.  The attention I received from Dr. Setya and his staff was beyond anything I have received before.   Dr. Setya spent a great deal of time explaining what he thought would be the best treatment for the future.  He was professional, courteous and caring.   His staff followed his lead.   I would highly recommend his practice for your future dental needs.

I am so happy to have been referred to Dr. Setya and his wonderful staff! I have been waiting many years to finally get my two lateral implants and process couldn’t have been better! He truly did a wonderful job from start to finish! Other offices that I had gone to over the years only made me feel overwhelmed and not safe about the process. But after having my first consultation with marisol and Dr. Setya I new this would be the end of my search. Dr. Setya took the time to go over the entire procedure with me two times, just so I could feel comfortable. Thank you so much Robin, Leah and Brad for
All your assistance in appointments and insurance questions. You all made sure that this worked for me financially and that means the world!  Thank you so much Marisol and Elizabeth for making me feel so welcomed and comfortable on my surgery and at the checkup! 🙂 I am truly excited and can’t wait to see the finished outcome!

Dr. Ajay Setya and his office specializes on Gum Diseases and I prefer to get my dental cleanings done here, because the staff is highly trained, experienced and professional and pay great attention to gum health and other issues that need attention, when one gets the dental cleaning done here. I have been coming to this office for a long time. I had the dental cleaning appointment here at this office in June 2019. I had a great overall experience with my dental cleaning and the hygienist was great, meticulous, very patient and methodical. She explained me which teeth had more plaques as compared to others and had gum issues related to those teeth. I am glad she was able to bring up those issues and go over in details about how to address those gum issues and other brushing methods. It was a great overall experience. Few years back, I had a dental implant done by Dr. Ajay Setya and he did an excellent job on that implant placement and I have never had any issues with that implant later on. He had given adequate local anesthesia, so i did not experience any kind of discomfort or pain. The procedure went very smoothly. He is very kind, compassionate, easy to talk to, professional, experienced, caring and used his expertise to do an excellent job on my case. His assistant staff is also equally wonderful and trained. I would always come back here to Dr. Setya again, if I would need an implant again in future. I would highly recommend this office your all dental needs. I have all praises and good things to say for Dr. Ajay Setya and his wonderful & caring staff and nothing less. I wish them all the best and success in future.
