Dr. Kim and his staff, including Yadi, Maria, Mireya, and Katie, are all amazing people! Dr. Kim makes every visit a great experience, and I truly am grateful that I found Dr. Kim. Every time I am at the office, Katie greets me with a smile. The staff go out of their way to make me comfortable and Dr Kim does incredible work. I have had crowns, fillings, and regular teeth cleanings, and each time I know I am getting the best treatment possible. I like that Dr Kim has the latest technology at his fingertips and he’s always so professional and tracks my history to see how my dental health is trending. I would highly recommend Dr Kim, but I also recommend his staff as well. They work together to make their dental office the very best!

I just finished getting my teeth whitened here and had an awesome experience. Everyone is super friendly and it’s an inviting environment. They even have Netflix to make certain you’re entertained while you’re t

I used to always hate the dentist because let’s face it there was never anything fun about braces and cavities and people telling you in a stern voice “relax your tongue”, and that’s why it’s always nice to find a place where you just feel comfortable and relaxed.

Dr. Kim is amazing, gentle, thorough, and high tech. He has discovered and treated a number of issues never addressed by my previous dentist. His staff is friendly and efficient. They never keep me waiting. They are the best!

I highly recommend this dentist. Dr. Kim is very gentle and it almost felt like a good massage when he was deep cleaning my teeth. He takes the time to get to know you and make sure that you comfortable. He also gives you a good explanation of whats going on with your teeth and makes good recommendations. I will definitely keep going to Dr. Kim, I’ve been to so many different dentist and by far he is the best. The staff are very helpful and friendly too.

My girlfriend and I just had our first visit here and LOVED it! Everyone at the office was so friendly and helpful. They explained everything in detail of what to expect, constantly checked in, and made the visit so easy!! Thank you Nicole for being the best at what you do! Can’t wait to do it again 🙂

Noemi G. from Garden Grove, CA (Source: Yelp)


As soon as I walked in I absolutely loved the office, the girls in the front were super friendly and welcoming! Dr. Kim was very thorough about the whitening procedure and made sure I felt comfortable the entire time. I was very nervous and anxious to come to the dentist, but this office put me at ease and made me feel super comfortable. After I saw the results I was very happy to see how great my teeth looked. Thank you Dr. Kim for making my smile brighter!

Arlene A. from Anaheim, CA (Source: Yelp)


I’m typically terrified of the dentist and all that comes along with it, because let’s face it most dental offices are scary and just extremely uncomfortable to be in, hence why most of us try to avoid dentist visits as much as possible or at least I do. It’s been a couple years since I last been to a dentist so naturally I was that much more nervous. Upon arriving  at Allegra I was instantly welcomed in great comfort which brought my anxiety levels completely down it was almost like instant relief. Visiting with Dr. Kim was a fantastic experience; He was very professional but very relate-able and extremely thorough, he really talked through exactly what my visit would consist of which made me very relaxed and comfortable. The office and stations at Allegra are very nice and clean and the staff was more than accommodating, I almost forgot I was in a dental office!! I am very happy with my experience at Allegra and I will definitely be recommending Dr. Kim to all my friends and family!!

Allegra Dental provides with me with excellent dental care. Dr. Kim is meticulous, informative, innovative, and friendly. His team members are equally impressive and exceptionally knowledgeable, especially Katie taking the time to explain the costs and insurance questions and providing me with flexible schedule for my treatments. The modern dental technologies, the cleanliness of the office, and the entertainment for their patients are simply impeccable. What matters to me the most is the human touch factor from walking into the office until leaving it: being greeted warmly, taking the time to clearly explain and thoroughly provide the needed dental treatments, frequently checking that I’m not in pain during the treatment, and ensuring that I understood the after-care instructions before a friendly good bye.

Karoline B. from La Puente, CA (Source: Yelp)


Nothing but good service at Allegra Dental! I went in for teeth whitening and the results were very good, not only that they were also quick! The place is very nice and there is nothing but good vibes! The doctor is great, definitely going back soon! They’re the best.

Carmen G. from Orange, CA (Source: Yelp)


Allegra Dental is the best dentist in OC. Dr. Kim explains steps and procedures very well before doing anything and is always willing to answer any questions. He is patient and takes his time to ensure that as the patient you are comfortable. Everything is of the best quality and prevention is key to this office. Super clean office. The staff are professional, helpful and informative. This office truly goes above and beyond. My husband and I are extremely happy and would recommend Allegra Dental to anyone. You won’t be sorry!!

It was my first time coming here to get whitening done, and it’s by far the best dentist I’ve been to. The staff and Dr are very attentive and friendly. The office is super clean and tidy which is an important aspect when you walk into any dentist facility. My over all experience has been amazing and I would highly recommend this dentistry if you’re looking to get phenomenal results.

If you are looking for a dentist or considering a change of dentists, Dr. Kim and his great staff with give you the professional treatment you deserve for years to come.

I just moved to Southern California from Ohio and needed to find a one stop shop for my dental needs, and Allegra Dental filled all of those needs. The office is completely remodeled with updated dental equipment (including flat screen with access to Netflix). The staff is friendly and extremely helpful. They went over various options with me for future Invisalign, as well as payment plans available if needed. Overall, very positive experience.

Hands down the best dentist I have ever gone to “and I have been to a lot” and will be my dentist for as long as he is in practice!!! I am telling all my family and friends to come here! Dr. Kim and staff was very kind, Explained everything very clearly to me. High tech state if the art equipment! I cant even tell any thing was done in my mouth after a root canal, the crown fits and looks like all of my other teeth. THANK YOU Dr. Kim & Staff for such an amazing experience. I would give more stars if I could!!!

I’ve been seeing Dr. Kim almost since he opened his practice in Tustin. His staff is professional and friendly, and I can honestly say that I have been completely satisfied with Dr. Kim and Allegra Dental.

Amazing dentist!!! For someone who is afraid of the dentist, who isn’t right? I felt really comfortable and well taken care of by Dr. Kim and his staff. He carefully went over everything and explained my options in detail. I hadn’t been to the dentist in awhile so I was a bit apprehensive,but i had an amazing experience and i will definitely be recommending him to my friends and family.

Dr. Kim and his employees gave me impeccable service during my visit. They were very efficient and friendly during my entire time there. I received my teeth whitening and feel more confident than ever when I smile. The moment I walked into Allegra Dental I forgot I was at the dentist because I felt very at home. The facility is very modern and well kept. They even have television screens to keep you entertained; making my visit much more pleasant than it already was. The Dental Assistant was also extremely friendly and constantly kept checking up on me to make sure I was not experiencing any pain. I received the results I wanted and am definitely coming back for all my future dental needs. Dr. Kim is very knowledgeable and an experienced dentist. It is very apparent that he loves serving his customers and going above and beyond to ensure we are happy.

If you’re looking to get your teeth whitened this is the place to come !!
I drove 45 minutes out of my way to come and get the teeth whitening service here and it was well worth the price.
The office and staff are extremely courteous and helpful. The whole process took around an hr and half and and i couldn’t be happier with the experience!!!
So if you’re in need of getting your teeth whitened i highly recommend this place =)

Cari V. from Anaheim, CA (Source: Yelp)


This place is amazing! Love my results for my whitening teeth! Came here to do my whitening  for a wedding since I’m going going to be a bridesmaid and I’m so happy how my teeth turned out. I definitely recommend you to come here.  Love it!

Roger P. from Elk Grove, CA (Source: Yelp)


My Emergency was taken care of while I was visiting Southern California family trip, was able to get the same day the Tooth repaired and my dentist back home 600 Miles away was really impressed with the quality of work he saw was done

Steven A. from Pasadena, CA (Source: Yelp)


Dr Kim is amazing. After having been in his office and seeing all his technology, I referred my brother in-law and a close friend to him. He was gracious enough to come in on a Sunday to accommodate them.  

My brother In-law had broken a crown done some years ago by another dentist. Dr Kim was able to remove the previous crown and create the new crown in just over an hour. My brother in-law was ecstatic and was able to eat lunch shortly after the procedure.

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


I made an appointment with Allegra Dental for a routine cleaning and check up. Dr. Kim and his staff were amazing! Not only were they all super friendly and accommodating, but very instructional about what exactly they were doing during the procedure. They have a customer for life!

Jesus P. from Placentia, CA (Source: Yelp)


This place is great! You’re free to watch some Netflix while you wait for procedures to finish, I had teeth whitening and was very satisfied with results. Everyone is really friendly and the place is quite nice! Great staff and they do a good job.

Estefany E. from Cypress, CA (Source: Yelp)


It was my first time here and my experience was awesome! They were very thorough, explained the  whole process and made sure that I was comfortable every step of the way. It’s really hard to find a good dentist nowadays, but I really liked this place and the people were really nice!

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


Nothing i hate more than the dentist, but they make it as painless as possible. great place.

Pedro Villa (Source: Google)


I can’t express how great this place was. The staff was amazing and very courteous. The place felt modern and cozy at the same time. Everything was clean and organized. I would definitely recommend this place to anyone that’s uncomfortable with the dentist as well. I felt at ease right off the bat because everything was explained to me thoroughly and precisely. I left confident in knowing that I would come back for future routine check ups. A+++

Dr. Kim is truly the best!!! His expertise includes the latest technology in equipment and skill. I’m 55 and my “mom” (best friend) is 82 and we both have had other amazing dentists throughout our lifetime, however, we both agree that Dr. Kim is the best! We consider ourselves blessed to have found him. One of the things we especially like about him is that he makes crowns in-house as you wait. This has provided the best fitting crowns with minimal adjustments that we’ve ever experienced. Truly amazing! Also, no office is complete without a great staff and Dr. Kim has surrounded himself with staff who are always friendly and very helpful. Allegra Dental is definitely a five-star office!!!

Lorraine N. from Orange, CA (Source: Yelp)


I have been seeing Dr. Kim since October 2015 for implant dentistry. I found out about his office through a brochure that I received in the mail.  I read about how the team was friendly and caring and that Dr. Kim used the latest technology to make patients’ treatment efficient and comfortable as possible.  What they described in their brochure was absolutely true.  I felt comfortable from my initial appointment.  Dr. Kim explains every process he will be performing prior to each visit and also on each visit.  Thus far, I’ve had a gum graft, porcelain/ceramic crown replacement and prophylaxis.  Every procedure has gone very well with almost no pain except for the normal slight discomfort. I also love their staff – Katie and Mireya.  They are both efficient and friendly.   Katie, Patient Coordinator, thoroughly explains all expenses prior to treatment and tries her best to accommodate my schedule .  Mireya, RDA, supports Dr. Kim and she does a super job making me feel comfortable as Dr. Kim works on my teeth.  I recommend Allegra Dental to anyone needing dental work.  I will continue as a patient even after my implant is completed.

James L. from Inglewood, CA (Source: Yelp)


Dr Kim is a superb dentist. His credentials are impeccable and he is highly knowledgeable and skilled. He is gentle and thoroughly explains what he is doing and why. He is honest and provides options for each step of treatment. His office staff are wonderful and his equipment is state of the art – very high tech. My wife watched her favorite TV series while getting two teeth crowned and barely noticed the work being done. I am truly extremely impressed with him. After treating my wife and I, we decided our children were better served by going to see him than their previous pediatric dentist. Dr Kim now sees my whole family. Its hard to find a good dentist but you don’t have to look any further.

Christina E. from Los Angeles, CA (Source: Yelp)


I had my first visit at Allegra dental this week. As any new patient I was a little nervous. The best surprise was for the first time at a dental visit, I was more comfortable than ever. All of the staff members were beyond accommodating and friendly. The office was very nice and I never felt like I was waiting around. I was seen right at my scheduled appointment time, and there was no pain in any of my treatment. I look forward to coming back and glad I found a great dentist from here on out!

Came here after waking up with extreme pain in my front tooth, called up Dr. Kim’s office and they had me in there within the hour. First impression, very clean and professional. The office is super nice and staff is always very friendly and welcoming, makes it easier to come back! Dr. Kim is awesome, he gives you options that are best suited for you and makes you feel very at ease. Went through everything he was going to do and showed me what was wrong on this crazy cool 3d scan they did. I ended up getting a root canal which was successful and surprisingly fast. You also get to watch Netflix! that’s a first for me! Lol. All in all I recommend Dr. Kim and his staff 100% I always walk out feeling like they really care! You won’t be disappointed!

Marley S. from Midway City, CA (Source: Yelp)


I love this Dental office! Its a very beautiful office and very clean. I usually get anxiety when I go to the dentist but not here. The staff is so friendly and always makes me feel at ease. Dr Kim is a great dentist and he will always take great care of you. Also I loved the fact that his office is up to date with high tech equipment. When I went to get my teeth whitening I loved that Mireya made me feel so comfortable talking to me, that I felt like I wasn’t even at the dentist. I love the office and staff I recommend it to anyone that needs a dentist! If you come in you will fall in love with the office and you will not want to go anywhere else 😀

Michelle K. from Anaheim, CA (Source: Yelp)


I love this dental office! Very nice and clean. Staff is friendly and Dr.Kim is very kind and caring. I really enjoyed getting my teeth cleaning while watching my favorite show on Netflix and I really appreciate Dr.Kim for taking his time doing a super good job cleaning my teeth. Overall I enjoy coming to this  dental office!
