Where to start…..?..Well Lets start off with me being 24 yrs old with no Dental insurance, paying out of pocket… The environment was so clean and the staff were EXTREMELY polite and caring. They made me feel so comfortable; also very knowledgeable about any questions I had….. Now as for Dr. Sanacore; I was told previously I needed a “Root Canal” but he gave me a second opinion and was able to save my 2 back teeth…..”EXTRAORDINARY!!!” He understood I was in a bind and need some help;(Most just want your wallet out!) he was so caring and understanding; he worked with me and got me the help I need and completely changed my life. I NOW can proudly say I am able to chew on the right side of my mouth. Something I have not been able to do for almost a year! THANK YOU SO MUCH DOCTOR AND STAFF, THANK SO SO MUCH!!

How many people, including children, can say they love their dentist?  I do!  So do my children.  I’ve been going to Dr. Sanacore for a few years now and I’ve never been happier with a dentist.  He is an excellent dentist and a very nice man.  My hygienist is wonderful too.  Gina is thorough and gentle. My children see Dr. Hanna, the pediatric dentist.  She is amazing with them, esp. my son with Down Syndrome because he has some sensory issues.  My kids actually like going to the dentist.   The entire staff is great, always helpful and great at meeting our scheduling needs(…).

I highly recommend Harbor Mesa Dental Care!  In fact, I have recommended several of my friends and they feel the same way I do.

I have been seeing Dr. Sanacore and his team for 13 years now, and I cannot recommend them enough.  Dr. Sanacore is super personable, highly competent and very honest.  I never feel like he’s trying to upsell me or milk my insurance with unecessary work.  He’s also very concerned with pain management, and he’s always checking in to make sure that I’m not in any discomfort.  I love, too, that he takes the time to explain what he’s doing and why he’s doing it.  

Everything at the office is new and ultra clean.  They use digital x-rays, so less radiation for me (yay!).  And my hat’s off to whomever does the hiring.  From the front office to my dental hygienist they all know me and greet me with big hellos.  It’s probably the friendliest place I go.  

It can be a real challenge to find a good dentist.  I’m so glad I found Dr. Sanacore!

Dr. Sanacore is the best! I’ve been coming here for almost 10 years and I recommend him to everyone who asks. He is friendly, explains everything clearly, and best of all, he is conservative with procedures – no unnecessary drilling!

Bridget M. from Pasadena, CA (Source: Yelp)


I am not a fan of going to the dentist and this is pretty much the best dentist I have ever been to. Dr. Sanacore and his staff are considerate, helpful, and talk to you about your plan and options, helping to make keeping your teeth and gums healthy an affordable and pleasant experience. I would recommend them to anyone!

I absolutely love this place. Gina the hygienist is super sweet and caring about my sensitive areas. She’s great with getting me through that part of my fears. Dr. Sanacore is amazing and really informative. Both my husband and I really enjoy coming here.

Don W. from Long Beach, CA (Source: Yelp)


If you are wondering about a good DDS to visit I can recommend Harbor Mesa Dental staff and Dr. Sanacore. Actually my whole family attends the office.

The staff are friendly and prompt with appointments and they have great technology such as text reminders and monitors in all rooms so you can see your xrays. Dr. Sanacore takes the time explaining what he is doing and helped me understand more about what is going in my mouth.

Today I was admitted first  thing in the morning as I had lost a chunk of my tooth the night earlier and in one hour I was on my way feeling better than ever.

Lastly we never had an issue with billing and they helped us with Invisalign and Zoom whitening.

It’s always a pleasure to go in and see the Harbor Mesa Dental staff. Everyone is warm and friendly, appointments are always on time, and they are excellent at their jobs and very professional. Most of the staff has been there 20+ years, a testimony to the great working environment!

Yolanda J. from Westminster, CA (Source: Yelp)


We have been with Dr. Sanacore (as a referral from co-worker) for 2 years now and we couldn’t be happier!  They are gentle, thorough, informative, and all around fabulous!! Just had 2 fillings done and I had no pain and no pressure!! If you are looking for a great dentist, this is your place! The staff is amazing also!!

Emma O. from Oceanside, CA (Source: Yelp)


Had my first visit to this place today, and it was the best dental visit I’ve ever had! All the staff is so friendly and nice, and it’s evident that they truly care about their patients. Dr. Sanacore was very kind and the first dentist to ever take their time explaining step by step what he was doing. I not only walked away with a great experience, but I actually think I know a bit more about dental stuff! 😀 I highly recommend this place to anyone looking for a a caring and professional dental office.

Honestly, I have had nothing but positive experiences here since I started coming to see Darlane and Dr. Sanacore 15-20 years ago! I cannot remember anything even slightly iffy happening! ALL POSITIVE! Is that even possible?! Apparently it is!

Tyler T. from New York, NY (Source: Yelp)


(…)I had Dr. Sanacore for my dentist and I love the way he went about with my exam. We first got X-Rays, and then he took the time to explain what the X-Rays mean. He went over the different sets of teeth and explained what he was looking for for potential problems. He then did a gum analysis and he explained that process too, about what the different numbers he was calling out meant and what to expect.

I really like the way he approached the exam, since he was explaining everything along the way, I understood why he took the steps he took, and it made me an overall more informed patient. On top of this, he had a very welcoming personality and helped to answer all the questions I had. He also wasn’t pushy about selling me products and focused mostly on the exam and my overall dental experience(…).

LOVE this office. I have had my teeth cleaned here for the last 15 years and have always loved the service and friendly staff. They are always flexible with appointments, which is great when most are scheduled 6 months out. I have also had more complicated work done here and they were super helpful with instructions and responsive to all the follow-up questions I had after my appointment. Also had Zoom whitening done here which I LOVED as a method of whitening for the long term. I would highly recommend this dental office for anything you need help with because of their professionalism and ability to cater to a patient’s needs.

Korinn S. from Laguna Beach, CA (Source: Yelp)


Very personable team. It’s easy to schedule appointments that fit within my schedule before work (most dental/medical is 9 to 5, but they open at 7) Team patiently listens and advises on my TMJ struggles. Very happy with teeth whitening treatment. I’ve felt taken care of for 20+ years and would highly recommend you trust your smile to this team.

Great service and great people. Darlene has been cleaning my teeth for 15+ years. Between her and Dr. Sanacore I feel like I’m in good hands. Highly recommended.

I have been a patient for many years, and now my kids and husband are also patients. What I love about Harbor Mesa Dental is the kindness, patience, and thoughtful care. I was sooooo scared of going to the dentist and they understand and took such good care of me that I now have no fear. Dr. Sanacore is very gentle, and Gina has taken good care of my teeth cleaning with no pain.

Cindi M. from Costa Mesa, CA (Source: Yelp)


I have been going to Dr Sanacore and Harbor Mesa Dental for.several years now but until recently only for cleanings.  I had to get two crowns this month something I was not looking forward to, but Dr Sanacore and the staff made the experience awesome.  Had little to no  discomfort from the procedures and my new crowns fit perfectly.  I would recommend them for a great overall experience.

Angela L. from Costa Mesa, CA (Source: Yelp)


I HATE GOING TO THE DENTIST. Always have, I had horrible teeth growing up which made the experience worse.

Dr. Sanacore has the lightest touch and has made coming for my check ups and maintenance a completely different experience – he’s patient with questions and proactive in his approach. Can’t say enough good things about him. If you’re a big chicken like me and need a dentist – I highly, highly recommend him.

The hygienist Sheena is also T H E B E S T. I’ve always, ALWAYS felt pain getting my teeth cleaned bec my teeth and gums are sensitive… but Sheena does such a great job that I would be willing to rearrange my schedule to get a cleaning appointment with her.

Super happy patient here!

I met Dr. Jeffrey Sanacore some 18 years ago and I would not go to anybody else. He is extremely meticulous and careful in all the work he does.
He did fillings bridges and dental implant and everything was perfect every time.
Also the hygienist Gina is amazing. She is working very hard and is very dedicated to her work.
The entire staff at Harbor Mesa Dental Care is very friendly. I enjoy going there.

I have seen Dr. Sanacore for a number of years and he has always been excellent to deal with. I recently had two crowns redone and he, in combination with the root canal dentist he referred me to, did outstanding work. The new crowns (on my front two teeth) look better than they have looked in the last 20 years. I give him and his office my highest recommendation. You won’t be sorry going to see him.

Harbor Mesa Dental Care is the most caring and skilled group of dental professionals I’ve experienced in my life! I know that sounds like grandeur, but, it’s not. I’ve been going there for nearly 10 years (and drive over 2 hours for appointments) and here’s what I’d like you to know about this amazing team. Dr. Sanacore truly cares about his patient satisfaction and in particular, with orthodontics. He and his staff have worked tirelessly and patiently to help perfect my smile. While many other dentists have been quick to suggest cosmetic changes (such as veneers that would cost 5-7x more than my current treatment plan) for corrective work, Dr. Sanacore was focused on getting to the root of the dental issue and never once pushed cosmetic changes. That being said, Dr. Sanacore has a knack for cosmetic dentistry and recommends those small, yet impactful changes that can brighten a smile that’s not obvious or fake-looking. I truly appreciate his work. His staff is also composed of bright, friendly, and efficient dental professionals who ease any anxiety one might have about treatment (a big thanks to Sally and Adele who are amazing). Some of his staff even do post-graduate research evidencing how much his team cares about delivering the best for your dental health. Lastly, the administrative staff really cares about getting you in to see the dentist is when needed and will work with your schedule, even on a Saturday for an emergency when you happen to chip a tooth on popcorn 🙂 I’m so grateful I found this group and looking forward to continuing in years to come.

Dr. Sanacore and the staff here are amazing. The dental care is top notch and PAIN FREE. Most visits I can barely tell anything is being worked on. I actually enjoy coming in for a visit, they are always friendly and seem to love what they do. The billing department works to maximize my insurance benefits, they are very careful not to hit me with out of pocket costs without discussing the options ahead of time. If you are looking for a new dentist, consider your search over!

Jeff L. from Long Beach, CA (Source: Yelp)


Great Dentist and Great Environment!

Dr. Jeff Sanacore was very knowledgeable and provided me a lot of information regarding my x rays and the condition of my teeth.  The equipment is state of the art and the office is very clean.  The staff is great and they really try to work with you and explain everything as far as what your insurance covers so you end up paying as little as possible.  I’d recommend this Dentist to friends and family.

C. R. from Costa Mesa, CA (Source: Yelp)


I highly recommend Harbor Mesa Dental. Dr. Sanacore is very informative and educated me about the current state of my teeth and the possible causes of how it got to this point. His dentistry work is excellent. He filled 5 teeth with composite filling due to receding gum line and overbrushing. He was efficient, thorough, and gentle around one of the sensitive gum line.

Both he and Gina (hygienist) talked me through everything they were going to do before proceeding and that’s always comforting. I appreciate quality work and great patient care.

Kourtnei R. from Santa Ana, CA (Source: Yelp)


They are so great! I needed to have some fillings. It had been about 10 years since I’ve been to a dentist because I’ve had horrible experiences. Of course I was nervous but they were so careful and very patient with me and even taught me things I had no idea I was supposed to do. They did an amazing job and I left pain free!
I highly recommend.

Candice B. from Costa Mesa, CA (Source: Yelp)


Dr Sanacore is the best dentist ever! Been coming since 2013, and have referred multiple families because of his skill and honesty. I never have to worry about being up-sold on treatments because he and the staff have proven over the years that they take a conservative approach first, and work with you to find out what your goals are. Finding an appointment and parking is always easy at this office, and I’m now halfway through an Invisalign program, and the whole process has really been a breeze because Dr S has guided me through the whole process! (…)

B. P. from Costa Mesa, CA (Source: Yelp)


Have been going for 5+ years. Dr Sanacore is great! He explains my dental issues well and leaves it up to me to decide if I should do the dental work or not. He is not pushy and is great in fixing the issues.  Hygienists Adele  and Sheena are awesome! His staff are super as well – nice,  friendly,  helpful,  and professional. Will continue to go to them for my dental services.

As most people I had the typical fear of going to the dentist… as an adult I kept that fear because of how much dental care cost. I am glad to announce that my fears are gone and I owe it all to Harbor Mesa and Dr. Sanacore. He is amazing and very informative, willing to work with you at creating a schedule in which you can afford your work and get it all done in a timely manner. His staff is very friendly as well and I always feel comfortable and at ease during and after my visits.

I will never go anywhere else (….) 🙂

I have been going to this dental office for close to 30 years. I used to have a terrible fear of the dentist before I found this friendly, competent practice. I have never had a minute of pain or a bad result in the many procedures I’ve had done over the years. I would highly recommend this dental office. They are among the best.

Christina L. from Long Beach, CA (Source: Yelp)


Considering I spend a lot of time at the dentist, I’m thankful I finally found one that is honest, respectful and affordable….definitely a happy camper!

I have had the pleasure of using Dr. Sanacore  and his staff from the hygienist, to the xray tech to the receptionist everyone was wonderful!  Dr Sanacore and staff demonstrated excellent professionalism, care, and attention to detail during my painless visit.  Staff was accommodating of my schedule and worked me in for a cleaning even taking care of a failed filling from a previous dentist during the same visit, on top of it on a Saturday! The procedure was completely painless they made sure I didn’t feel a thing with my sensitive teeth. I use to afraid of going to the dentist and always have dreaded a visit to the dentist, but Dr Sanacore and his staff have changed my mind about going to the dentist.  If you are looking for an excellent dentistry team look no further than Dr Sanacore and the staff at Harbor Mesa Dental Care. Hands down the best dentist experience I’ve ever had they were impressive in all areas!

I have been going here since I was a kid and I now take my kids. I have gone to other dentists but I haven’t found anywhere better.

Kathy P. from Phoenix, AZ (Source: Yelp)


I no longer live in the area but Dr. Sanacore and all of the staff at Harbor Mesa Dental Care are amazing !  I moved out of state 7 years ago but was lucky to find another practice that has similar traits and business practices.  My adult kids have been patients of Dr. S for 17 years!
