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


Dr. Ahn removed my fractured tooth, did a bone graft, and implant.  While it wasn’t my idea of fun, it was a very successful experience. I felt comfortable with every step of the process. He gave me plenty of information in person and in writing. His office called to follow up on me. So, I didn’t hesitate to go to him again when I fractured another tooth on the other side of my mouth! (I’m now wearing the night guard that my dentist recommended.) Again, I feel very fortunate to have such a competent doctor.

Our family would like to share our experience with orange county families. Dr. Ahn And his entire staff from the sweet accommodating professional Girls at the front desk to the entire back-office staff could not have provided us with more relaxed comprehensive amazing communication and service with a complete sense of trust in dealing with our daughter’s extensive surgery, this is the second time we have worked with the team and we will have a third coming in 2020 We would like to with all confidence recommend anybody needing any oral surgery to book a consultation!!

Dr. Ahn and his team are amazing. Had a wisdom tooth removed and it was practically painless and was quick. Marla the front receptionist was very knowledgeable and upfront with the costs, no hidden fees. She even called the same day to check how I was doing after the procedure. The dental assistant was also helpful during and after the procedure explaining what I should eat and take to minimize pain and for prompt healing. The next day I was able to resume normal activities. Thank you Dr. Ahn and team!

Jenny P. from Trabuco Canyon, CA (Source: Yelp)


I was referred to Dr. Ahn by my dentist for the removal of my upper center front tooth and to proceed with an implant.  I never felt any pain when he removed my dying tooth or during the placement of the implant post, which was done at the same time since my bone was strong.  Normally, this is not the case…so I was lucky and my entire process was shortened by several months!   Dr. Ahn explained every step along the way.  You need to be patient for the bone to get strong.  The process required for an excellent outcome is long.
This was my front tooth and I am so pleased with the final outcome!
I highly recommend Dr. Ahn!

John Antony C. from Capistrano Beach, CA (Source: Yelp)


Dr. Ann is not only highly personable, which engenders trust from the outset, but offers a level of expertise and empathetic medical care that would be hard to match anywhere.  His willingness to treat my problem at short notice, and the unhurried skills that he exercised in doing it were remarkable, making what might have been an unpleasant experience anywhere else very calming and straightforward.  In addition, his staff is outstanding in every way, making you, the patient, feel as if you are the only patient in the office.  Thank you to all.

Julie S. from Lake Forest, CA (Source: Yelp)


My son had his wisdom teeth extracted approximately one month ago. We went in for an initial consultation and exam, and Dr Junil was on time, quick and to the point (in a good way).   Answered the few questions we had, and so we set a date for the surgery.  I always check out doctors credentials,  and check for complaints filed, etc. and Dr. Junil had everything in order and I felt very comfortable with him taking care of my son.  The surgery went well,  and he had no complications, and everything seems to have healed up nicely.  I would definitely recommend him!

Dr Ahn did an excellent job at removing my four wisdom teeth in a timely manner and with professional care. The recovery process really only took 2-3 days before it was just a dull pain that was easy to handle. Overall Dr Ahn did an excellent job and was worth the visit.

Jake F. from San Luis Obispo, CA (Source: Yelp)


Dr. Ahn was recommended to me to remove my 3 wisdom teeth. I had a great experience overall, and it was a very quick and easy procedure. The facility is nice, and all of the staff treated me extremely well and made sure I was comfortable. The surgery was very fast, and the recovery was much better than I expected. I would highly recommend Dr. Ahn and staff to friends and family!

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


My daughter had her wisdom teeth out a  few weeks ago and it went very well. Dr. Ahn went above and beyond. My daughter had no swelling or pain and was ready to go on her 6 mile run the next day(which I made sure she didn’t btw) I will refer all of my friends and family to him.

Samantha F. from Mission Viejo, CA (Source: Yelp)


This office is super great! I was referred to this office by Mission Viejo Dental Associates because I needed to get all 4 wisdom teeth removed. The staff here are very nice and help made this first time experience super easy. My surgery was done by Dr. Junil Ahn and the process went very smoothly. He is a very nice doctor and was able to answer my questions and made me feel confident and not worried about the surgery. The office is also very clean and well decorated. Thank you to all the staff for your help!

Sasha A. from Laguna Hills, CA (Source: Yelp)


Dr. Ahn is the most professional, caring and exceptional oral surgeon. And his staff are more than amazing and sweet. I have been postponing to get my wisdom teeth out because I was scared. After scheduling my appointment talking with the doctor and his staff they were extremely helpful, informative and caring.

I got 3 wisdom teeth extracted, with VERY minimal swelling (no chipmunk cheeks) and very little pain. I can’t thank Dr Ahn and his staff enough for being so amazing and making me so comfortable during the process. Would recommend them a million times over!!!! So grateful for Dr Ahn thank you!!!

Zo S. from Topeka, KS (Source: Yelp)


(…) I just had my 4 wisdom teeth out and I don’t know if I’m a miracle case- it’s too soon to say- or my doctor was just so good at his profession- that my mouth looks completely normal (NO swelling) and literally only one side has minimal pain. I am so relieved by how relaxed and great I feel! The whole procedure was as expected, I didn’t remember or feel a thing! But before I ‘went under’ I remember how sweet the staff was at calming my nerves and relieving my anxiety. The doctor was quick and kind. Made me feel like I was in great hands. I can guarantee if you come to OC Oral Surgery you won’t be disappointed! Great place, great people, and honestly GREAT Experience! Maybe I’m lucky but I truly thank you for such an easy process!

Mike T. from Valencia, CA (Source: Yelp)


Our daughter had a gingivectomy done recently at OC Oral Surgery, and what a wonderful job Dr. Ahn did for her front teeth and smile.  Not only was he very professional and knowledgeable in his field, he was very kind, patient and gentle with our daughter who is deathly scared of any dental procedures. The whole experience was quick, easy, and painless. She was very happy with the result and the way it changed her smile. Dr. Ahn and his office staff are awesome! Thank you for the excellent care given to our daughter. We highly recommend this place.

Julie L. from Gilroy, CA (Source: Yelp)


We received excellent care and service for my daughter’s wisdom teeth extractions. Dr. Ahn and his staff were very warm, friendly, and kind. When my daughter developed dry socket, she received treatments with compassion and gentleness until it was completely resolved. I highly recommend Dr. Ahn and his team!

Jill S. from Dana Point, CA (Source: Yelp)


My 12 year old son needed to have 2 teeth pulled prior to getting braces.  Dr. Ahn and his staff were wonderful.  The appointments went smoothly, we didn’t have to wait.  They were very timely and efficient.  Scheduling was very easy.  He had to go under general anesthesia to have the procedure done on a Monday morning.  He had very minimal swelling and essentially no pain.  Monday afternoon I turned around and he was eating a Drumstick, of course, the entire top part with all of the nuts he had already eaten.  I looked in his mouth and there was a nut in the hole where the tooth had been pulled.  He swished with water and it rinsed out fine.  Who eats a Drumstick 6 hours after oral surgery??? Typical 12 year old boy!  He woke up Tuesday morning and was ready to go back to school.  A Huge Thank You to Dr. Ahn and his staff.  My son is very excited to have his braces on 🙂

Bruce H. from San Diego, CA (Source: Yelp)


Dr. Ahn did a fantastic job removing all 4 of my wisdom teeth. He was very informative and answered all my questions. I was in and out of the office in about 1 hour and had no pain after. His staff is super friendly and made me feel comfortable the whole time.
I would recommend Dr. Ahn for any wisdom teeth extraction.

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


OC oral surgery was awesome. Our 7-year-old daughter had to have 4 molar teeth extracted.  They were all great, Dr Ahn did an amazing job…… and Kelly Eichner his assistant was awesome so good with our daughter she made her feel super comfortable. They also extracted my husband’s wisdom teeth a few weeks before this as well and the Same experience. Nice, professional ..kind and gentle.

Heather R. from Ladera Ranch, CA (Source: Yelp)


My teenage daughter had all 4 wisdom teeth removed one week ago–and we had a fantastic experience at OC Oral Surgery.  Dr. Ahn and his staff were caring, professional and very thorough.  We were well informed of the procedure ahead of time, were given thorough post-surgical instructions and even got a phone call a couple hours after to see how she was feeling.  Her pain and swelling was minimal and she felt great the next day.  I appreciate the kind care that was given to her.  I would recommend this office very highly.

S. C. from Mission Viejo, CA (Source: Yelp)


(…) I felt completely at ease and comfortable. I have a bit of anxiety but I did not feel anxious at all, those ladies were so wonderful. Dr. Ahn entered the room, greeted me and then started the IV; that’s really the last I remember until it was all over. The post-op care instructions were very clear. I was home an hour later and feeling fine. I had no pain until the 2nd day and it wasn’t bad at all, 1 ibuprofen did the trick. After that I had no other pain. I followed the orders completely!! My post-op check-up was great, everything healing perfectly. I highly recommend OC Oral Surgery. Dr. Ahn and his whole staff are excellent, highly skilled and proficient. They made this experience so pleasant, sounds strange to describe teeth extraction as pleasant but it really was – the procedure and recovery were super easy. Very, very pleased! I had my other 2 wisdom teeth extracted many years ago and I had an entirely different experience, that office was awful. OC Oral Surgery has restored my faith in dentistry. Extremely positive experience.

Dr Ahn did removal of my wisdom teeth (and I am older which makes it more challenging). He did excellent quality work! Procedure went extremely well and everything went according to expectations. He accurately described the procedure and timeline – and was great responding directly to my email inquiry to confirm healing process (…). Highly recommend the practice.

Dr. Ahn helped me to remove my wisdom teeth. I had a great experience with them. Office is very clean and homie, all the staff are super friendly and always greet you with a smile. I would definitely recommend them

Norman Y. from San Marcos, CA (Source: Yelp)


Recently my (…) dentist referred me to Dr. Junil Ahn for problematic post-implant-related surgery.  The surgery went well, and I am enormously heartened by Dr. Ahn’s expertise, skill and courtesy, as well as that of his entire office staff.  I recommend Dr. Ahn enthusiastically and without reservation.

Dr Ahn and his staff are kind, knowledgeable and clearly enjoy helping people. I am so grateful I found Dr. Ahn.

Jennifer J. from Mission Viejo, CA (Source: Yelp)


I have taken my daughter to see Dr. Ahn twice, which is obviously more than I would prefer for a newly 2-year-old…but it is what it is. We had excellent care with Dr Ahn!!
She was seen at 18 months for a frenectomy (lip tie). It was an issue since she was born, but we always found a workaround. When she was 18 months she was super behind in how she managed solids, but the frenectomy resolved that. Dr Ahn was caring and supportive and then anesthesiologist (…) he works with is just as great!
We were seen again last week for an infected tooth. Dr. Ahn & (anesthesiologist) did a great job once again. It’s so scary having to put your baby to sleep, and the doctors and office staff were sweet and supportive.
(…) Honestly I hope we are done with this office, lol but if we need an oral surgeon again, we will come back here!

Steven S. from Lake Forest, CA (Source: Yelp)


(…) During the course of my investigation for the ‘Perfect Doctor,’ I was given Dr. Junil Ahn DDS, MD as a consideration by our family DDS for 15 years.  Now, have you ever had one of those encounters, when a Doctor and Staff are truly amazing?  Well, it just happened to me, with OC Oral Surgery Staff and Dr. Junil Ahn DDS MD.  Never before have I experienced, the treasured concern(s) for a patient and the professionalism by Doctor Ahn.  Dr. Ahn and his staff, extended indispensable and appreciated services to my Son Mark as he goes through this frightening phase into Adulthood.
Thank you OC Oral, your professional nature is a gift to us all.  Respectfully, another satisfied Patient.

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


I was referred to Dr. Ahn by my dentist after an extraction went wrong causing a hole through my gum and bone to my sinus. I was somewhat distressed but I found Dr. Ahn to be extremely professional and reassuring. My treatment was described very well and addressed my concerns. I felt very well treated by the staff there, left feeling confident the procedure had been a success and received really thoughtful post-surgery follow-ups. I never knew this kind of thing could occur but I’m very glad to have this level of care and skill in my health plan.

Jenny N. from Ladera Ranch, CA (Source: Yelp)


My son had all of his wisdom teeth removed at one time.  Thanks to Dr. Ahn’s surgical skills, he had no pain!  I would definitely take my daughter to Dr. Ahn when it’s necessary to have her wisdom teeth removed.  All the employees were very pleasant, Thank you OC Oral Surgery!

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


My 9 month old needed a procedure and Dr. Ahn and his staff were so gentle, kind, and caring. Dr. Ahn was very thorough and answered all my questions at our consultation. After our procedure they called to check on my son and to see if we had any questions. I highly recommend him.

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


Dr. Ahn is the best oral surgeon that you could ever want. I needed to get my two bottom wisdom teeth removed as they were causing shifting to my middle teeth and were causing pain when I would chew so I started looking online for an oral surgeon to do the job. I looked through countless reviews and found that Dr. Ahn had the highest rating of stars and reviews so I decided to go in and have a consultation with him. Let me just say I hate being in the dentist chair but Dr. Ahn with his calm presence and knowledge actually put me in complete ease. I was actually able to make the appointment with him and not feel worried because of how calmly he spoke of the procedure. I got my procedure done a week ago and am writing this right after my post-op appointment. The holes are closing and there is no infection present which was something that did frighten me. Dr. Ahn made sure to give me the correct medications that wouldn’t interfere with some of my current medical issues so that I would have the best recovery possible. Dr. Ahn is amazing and so is his staff I would recommend him to anyone that needs to get any type of oral surgery done as I know he would be the best doctor to get it done. Thank you so much Dr. Ahn and your staff for making this experience a pleasant one!

Kimberly B. from Newport Beach, CA (Source: Yelp)


I had such an awesome experience here, everyone was very friendly and accommodating. Dr Ahn was so thorough and I felt very comfortable I had 2 implants done here and it was wonderful

Heather H. from Dana Point, CA (Source: Yelp)


My eight-year-old daughter needed two teeth extracted and was very nervous going into the appointment. The staff at OC Oral surgery completely put her at ease and had her laughing. They were very supportive to me after the procedure when she was a little groggy from the sedative. I really can’t say enough positive about the whole experience, including the follow up calls to check on us.

Steven N. from Westminster, CA (Source: Yelp)


Dr Junil Anh was amazing for squeezing me in at the end of the year. I am also really appreciative of his team working (…) to make the wisdom teeth removal into an affordable range that I could afford. The surgery itself was extremely quick and I barely felt any pain after the first day. Dr Anh himself was extremely informative and helpful with any questions.

Debby S. from San Clemente, CA (Source: Yelp)


What a blessing to find this office! Needed a quick appointment to have our daughter’s wisdom teeth out before she headed back to college and they couldn’t have been more accommodating. Her 4 extractions were slightly a bit more complicated but the staff and Dr. Ahn made her feel secure and eased her nerves. They were easily (and happily) available hours and days after for any questions and/or concerns.
We would highly recommend Dr. Ahn and his entire staff to anyone needing oral surgery.
Thank you Dr Ahn and Staff!

Nancy A. from San Clemente, CA (Source: Yelp)


Dr. Ahn and his staff are without a doubt one if the friendliest professional practices I have dealt with. Dr Ahn does incredible surgery. Explains everything precisely and in a relaxing comforting manner. I recommend them highly.

Leslie B. from Dana Point, CA (Source: Yelp)


Dr. Ahn and (partner doctor) are very professional and experienced.  My son at 16 had all four wisdom teeth removed.  He had no problems at all afterward, and very little discomfort.  The office runs on time, the staff is helpful and the reception room is relaxing.  Dr. Ahn and (partner doctor) both take time to answer your questions and do not rush you as a patient.  I highly recommend Dr. Ahn and his staff.
