The only dentist I’m whiling to see! Dr Cohen is the only doctor in the history of doctors to ever give you a shot on your gums and you won’t feel it! Well, unless he misses!  jk! Kidding aside, hands down the funniest, sharp, helpful and most affordable out there. He does fine work, painless and reliable. Super friendly and did I mention funny?! He loves to make people laugh and he’s always in a great mood no matter what! The staff is great also, trust me, it’s a great place to get your smile up to your standard! Go see for your self! You will be happy you did

Dr. Cohen is very honest and polite dentist. He has been practicing for probably more than 25+ years. He is a funny, friendly guy who is extremely knowledgeable of his field. He is excellent at administering anesthesia. His is very observant of everything occurring with his patients. He did very well with my 4 year old and 12 year old. A wonderful dentist !

Lisa B. from Santa Ana, CA (Source: Yelp)


My family and I absolutely love Dr. Cohen. My mom, dad and my immediate family all see Dr. Cohen. He makes you feel very comfortable in the office. I absolutely HATE the numbing shots and he makes it so you don’t really feel a thing. Hes very flexible and fits you in if you have pain or a emergency. His prices are very affordable and he works with you. He listens to you and what you have to say and does everything in his power to make you feel better. I recommend him 110%!

Joy B. from Fullerton, CA (Source: Yelp)


Dr. Cohen is, hands down, the best dentist I’ve ever been to! As a child, I had a very tramatic experience. I’ve been through, at least 10 different dentists’ in the past 7 years.  Most dentists’ didn’t care about my extreme fear, or tried to charge for things I didn’t need done. Dr. Cohen has a very flexible schedule and is very honest. He’s a very funny guy, which helps you forget you’re even in a dental office. My husband and I are beyond satisfied with the service he provides, that I even take my 2 kids (5 & 12) to him. He’s excellent with children. One more thing, he gives the best shots I’ve ever gotten. You can’t feel a thing. I live in Fullerton,  but drive all the way to Santa Ana because Dr. Cohen is simply the best!!!

Tracy G. from Costa Mesa, CA (Source: Yelp)


Finally an honest dentist. Switched to him from my prior dentist who was extremely dishonest and handled Patients teeth like a used car lot! Dr. Cohen is amazing, honest, and is great to talk to. He explains dental procedures so I could understand, is affordable and very honest. I am so happy our family found him:)

 Missy B. from Long Beach, CA (Source: Yelp)


It took me a long time to find a dentist I like and trusted. A coworker recommended Dr. Cohen to me and I am so happy they did. I have been a patient for about 2 or 3 years now. Dr. Cohen tells it like it is, is friendly, professional and a great dentist. No up-sell or unnecessary procedures have ever been recommended. The staff is wonderful as well.

Heather Z. from Santa Ana, CA (Source: Yelp)


When I tell people I am heading to the dentist, they cringe, but I don’t know why – I love my dentist! Love Dr. Cohen, love his team! You get experts who listen, clean and get you in and out of the chair as quickly as you are comfortable with.

Kelly G. from Parker, AZ (Source: Yelp)


I was a Registered Dental Asst for Dr Cohen for 5 years (1988-1992). I sent my kids, parents, siblings, uncle, aunt, cousins and friends to him. To this day, my kids say he was the best dentist ever. If they didn’t live in Montana, Missouri and Guam, they would be bringing there own families to him. He is absolutely magical when giving injections. Not only is he a fantastic dentist, he genuinely cares about each and every patient that walks in the door. If you felt rushed at all in his office, it is because he has so many loyal patients and he is super busy. Just check out all the hours he works. You may have to wait a bit when you get there, but let me tell you, DR COHEN IS WORTH THE WAIT. Bottom line, he is an awesome dentist and was an awesome employer, best ever. If you happen to read this Dr Cohen…Miss ya bunches, Kelly Gates, Surgical RN

Dr.Cohen “KING OF DENTISTRY” “MY HERO” Honest and an expert.He saved three of my teeth and one of my husbands teeth Walnut Dental wanted to pull them.Dr Cohen has a great bedside manner as well.Highly recommend. He is old school and truly knows Dentistry like no other I have ever met EVER! WE LOVE DR.COHEN!!!

Candice M. from Fontana, CA (Source: Yelp)


I had a root canal done today for the first time And Dr. Cohen was amazing! Very informative throughout the whole process and helped ease my anxiety. Totally recommend him! Oh and his shots don’t  hurt at all!!!

John B. from Fullerton, CA (Source: Yelp)


Dr. Cohen and everyone here does a great job. I have been a patient for years, and will continue to visit. No nonsense dentistry with a straight forward manner.

Annie M. B. from Westminster, CA (Source: Yelp)


Dr. Cohen is the best dentist I’ve been to by far. The shot process was painless(for those who have bad experiences) Also, the dental work is fast & Efficient. No pain AT ALL. S/o to all the dental assistants they were fun and made the process Fun & 100x better.

Ali O. from Newport Beach, CA (Source: Yelp)


I felt the need for an update for these great people. First off, Evon you are great, you are a master in keeping up with everybody’s appointment  and i really felt your absence when i needed the doctor last summer and when you were on your vacation. New assistant is super friendly, fast and skillful.  She trimmed my temp caps for 85 times and she  was still friendly 🙂 And the master, Dr Cohen is all you need when you have something going on with your teeth health. Do not get fascinated with other dentist offices that are full of paintings and horse statue ( like i care when i have the worst pain). You cant match his professionalism anywhere else and also the way he handles his patience. He is gonna save your broken tooth and charge you less unlike those fancy dentists where you have to have an implant for a fortune. I recommend him to anyone and i am bringing my family here in future. Stay young doctor, we need you!

O. P. from Irvine, CA (Source: Yelp)


Dr. Cohen is my dentist since 1995. He is smart, funny and expert in his field. He is old timer. I will be sad when he retires. His office is old, old rusty equipment but who cares. I care for his skills. Yes. he is very honest dentist who will not scam you with extra treatments not needed. He is very hard working (works six days a week, longer hours since I know him). He is passionate about his work and it is his life. He can retire, because he worked hard for many years and is very successful and his children too are very smart medical doctors but he loves his work. He is the funniest dentist, reminds me of Seinfield’s Larry David. Dr. Cohen is also from New York and has his accent which is very sweet. He was an Engineer and then became a dentist in 70’s so he has both skills to apply. He is very humble too.

Patti A. from Tustin, CA (Source: Yelp)


I’ve been seeing Dr. Cohen for years. As does my whole family of 5. When my twons needed braces Dr. Cohen managed to fit is in and in 4 days pulled 8 teeth from 1 child and 9 from the other. This service allowed my girls to get going on their treatment promptly and efficiently. But mostly my kids love Dr. Cohen and swear he gives the best shots..they dont hurt. Even After many extractions my kids have no anxiety going to Dr. Cohen. Most recently I was in need of extensive dental work including extraction, bridges molds etc… Dr.  Cohen took my extensive procedures and now I have a beautiful smile again. His schedule is very flexible open early and late daily and open on Saturday. I definitely recommend Dr. Cohen. And his assistant Wendy is the best.

Shelby D. from Corona, CA (Source: Yelp)


Like so many other reviewers said….BEST DENTIST EVER! I have been seeing Dr. Cohen for the past 12 years, and my mother has used him for the past 25 years. I wouldn’t trust another dentist with my teeth the way I do Dr. Cohen. He is friendly, smart, knows exactly what he’s doing and doesn’t talk you in to getting unnecessary procedures. He knows people don’t have all the money in the world to spend on out teeth if we don’t have to, and he respects that. I recently moved further away, and I still make the  1 hour commute to see him. You will never have an horrible experience with him like the ones you hear other people talking about with their dentists. There’s nobody better than Dr. Cohen 🙂

I called Dr Cohen’s office at 7am because I had tooth pain all night. He answered the phone and told me to come in right away. He was professional and addressed my pain. Dr Cohen shows genuine concern for his patients. I always refer anyone who needs a dentist to Dr Cohen.

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


I have had the  privilege of knowing Dr Cohen for 28 years. Dr Cohen is the only dentist that I have allowed to work on my mouth. Based in Santa Ana I have travelled from as far as Lake Elsinore to preserve this relationship and to have this exceptional Dentist tend to my root canals. Dr Cohen always made me feel special, took time to explain the procedures and most of all make me laugh, without laughing gas. Dr Cohen knows his clients and his work speaks for itself. He has rebuilt my mouth over the years. He hires the best staff as well. I highly recommend this hard working, dedicated Dentist that performs quality work. A dying breed to say the least.

Anonymous from Irvine, CA (Source: Yelp)


Very honest dentist. Just like CF said, not fancy office, does not have the latest equipment, old furniture, but he only recommends treatment that’s necessary without the inflated price. Dr. Cohen ha been practicing for probably more than 25+ years, he is a humorous and friendly guy. He will tell you his life story, his wife, his adult kids, his house, everything! He gives pain free shots that even my kids did not even know that he’s already done. He charges according to the insurance booklet, does not inflate price, treats you all the same whether you have HMO, PPO, or cash. He is also very accommodating to patient’s schedule, he is a very dedicated and honest dentist that I highly recommend. Best to make the first appt of the day to avoid the wait because he really cares and spends enough time with each patient.

Jose A. from La Habra, CA (Source: Yelp)


Dr. Cohen runs a small operation but he is the best dentist I’ve ever gone to. He is honest, friendly, and personable. I’m glad I gave him a shot. If you want to get lost in the shuffle at the fancy big dental shops then go ahead, more Dr. Cohen for me.

Ebert B. from Anaheim, CA (Source: Yelp)


He is very good at what he does. He will explain what procedure you need and why. I have been going to Dr. Cohen’s office for about 8 years now and he is very honest. I once took my kids to one of those “carnival kiddie” dentist offices where you wonder if you are being charged for the air conditioning in the building. They told me my son and daughter had tons of work and an extraction that was needed. I was hesitant at first to take my children anywhere else–knowing how frightened they were. However, I needed a second opinion and I got one. Dr. Cohen told me my kids did not need much work done and made sure my children were comftorable. They are no longer afraid to go to the dentist and I feel confident taking them with him. I highly recommend Dr. Louis Cohen to all of my friends and family.

Linda S. from Fullerton, CA (Source: Yelp)


He is a good dentist…and I’ve been to a couple bad ones…He has done two crowns for me and cleaned my whole family’s teeth. The wait can be long, but he is good. And his novacane (sp) shots do not hurt a bit. I’m a bit afraid to Yelp him becasue the wait will get longer!!

The M. from Steamboat Springs, CO (Source: Yelp)


Dr. Cohen is not only personable, but hilarious. Me & my husband went to see him for the first time today and we immediately felt like we’d known him for years. The first thing he told me is that he knew my husband was from the mid west and that I was a California girl. I asked him “How’s that? Does my husband have a mid west way about him?” he said “No, by his social security number! I know these things!”
He was non stop fun the whole time. I felt like I was at a dental improv. If you’re nervous to go to the dentist, he’s your guy. If you like to laugh, he’s your guy. He’s professional and an absolute delight! Thanks Dr. Cohen!

Scarlet M. from Orange, CA (Source: Yelp)


I love DR. Cohen. And no I do not over exaggerate that. He is awesome! I’ve been going to him since I was a little girl and my family and I are very fortunate to have such a caring dentist that we trust and can tell us how it is and what kind of work we need done. Easy to talk to and just a simple and non stressful visit every time I go and see him. Thank you for being so amazing ! I appreciate you and your staff more than you know. You are all awesome!

Johana M. from Fullerton, CA (Source: Yelp)


Hands down the best dentist, ever! Dr. Cohen is incredibly nice and he understands that money does NOT grow on trees. I do not have dental insurance, I pay out of pocket every time and he is so understanding when I need a little more time to come up with the whole payment. I have hated going to the dentist all of my life, particularly because the idea of a needle piercing my gums is terrifying! I never felt the needle when he has had to numb me up, his technique is flawless! I have gotten crowns here, fillings, root canals, and I got a wisdom tooth extraction (I was not under anesthesia). I asked him to removed the tooth in one piece (if possible) and he did just that ! I also had an infected root canal and I called in without an appointment he rushed me in and made time to see me. The removal was the next day!  The staff is nice, but I come here because Dr. Cohen is honest and hardworking — he understands that tooth aches are serious and can interfere with daily activities. His rates are superb!

Alanna B. from Santa Ana, CA (Source: Yelp)


I love Dr. Cohen. I’ve been going to him for practically my whole life and always enjoy seeing him. He makes you feel comfortable since going to the dentist can be a scary thing for some people. He is very friendly. Also he does make himself available if there are any issues that you have. The only things I’ve had to get done at his office besides x-Ray, cleaning and fillings, was getting my wisdom teeth pulled out and boy can I say he gives the best shots ever and I’m a type of person who hates getting shots at the doctors. I understand what some reviewers are saying that they feel “rushed” and I have had a few times where I didn’t get in at my set appointment time, but he is still very thorough with each of his patients. I would definitely recommend him if anyone was looking for a good dentist.

Steve K. from Irvine, CA (Source: Yelp)


Honest, fair, reliable, old-fashioned dentistry. The first time I went in, I didn’t realize he doesn’t take debit or credit cards. Cash or checks only. He didn’t miss a beat, just told me to get him next time! Not “bring it by tomorrow”. Not “mail it”. Just pay me next time. Granted, some of the equipment looks a bit past its prime, and you won’t get fancy digital xrays here. What you will get is, as I said, honest, fair, reliable, dentistry. No inflated prices or “Treatment plans”. Just good, simple, dental care.

Karina S. from Orange, CA (Source: Yelp)


Dr. Cohen has been my dentist for a decade and at 30 years old that’s a third of my life! He has taken such great care of my dental needs. 5 years ago my son was born with cerebral palsy and lots of medical issues. I ignored my dental health and when I finally made time to go Dr. Cohen kept me positive and promised slowly but surely we’d get my mouth back in order. Finally after a year and a half of major work I’m happy to say we are pretty much done! I am so thankful and grateful to have not only a great dentist but a wonderful person working on my teeth. I recommend any and everyone to pay him a visit for anything from routine cleanings to major root canals.

Albert G. from Tustin, CA (Source: Yelp)


First time patient, I haven’t been to the dentist in 15 to 20 years. As normal, I was mortified. As soon as I spoke to Dr. Cohen I knew I was in great hands. He has a great sense of humor made feel at ease. I highly recommend seeing Dr. Cohen!! God bless.

Milton D. from Buena Park, CA (Source: Yelp)


I come here every 6 months to do my cleaning they are very honest and they do a very clean and good jobs I have been to many dentists but Dr Louis is the best no question asked he is not going to do thinks you don’t need and he is open on Saturdays witch helps a lot.

Helene C. from Tustin, CA (Source: Yelp)


I have always been afraid of dentists my whole life.  Dr. Cohen has actually made me enjoy going to the dentist.  He is kind and patient and does not try to “sell” you work that you do not have to have done.  I do not have insurance and his prices out of pocket are very reasonable and he allows me to make payments for work that needs to be done.  The office is not “fancy” but it is clean and friendly.  I am so glad that I found Dr. Cohen and would recommend everyone to try him.

Angela C. from Henderson, NV (Source: Yelp)


I Love Dr. Cohen, my family has been going to him for years, he calls himself a mouth machine, he’s great, he’s an old school dentist, honest, answers his owns phones, no computers, not at all like these new age dental offices that wanna Nickle and Dime you and don’t care about their patiences. Dr. Cohen cares and his office staff is very friendly.

Virdi A. from Riverside, CA (Source: Yelp)


Love Dr. Cohen’s office. I have been going for 15+ years to his office. It is true about other reviews that he is really honest about pricing, he doesn’t try to scam you into something you need. I have to pay a little extra to keep my dental PPO insurance and drive from Riverside just to see him but it is worth it. It is not a fancy looking office but he really treats you well; he always asks me how my brother and other members of my family are doing. I recommend him to anyone that needs an honest, good dentist.


It was forty years ago that I ventured out of New York City, New York with my new bride to southern California after having joined the United States Air Force as an officer, serving in the capacity as a dentist. While my time in the military was honorable and provided me with remarkable training, I only served for five years, leaving as a Major in the Air Force. I graduated from Columbia University School of Dentistry in New York knowing that both my wife and I wanted to move west to a warmer climate. The United States Air Force provided me with the excellent opportunity to make this dream come true. When I left the Air Force, I joined a large dental practice in Riverside, California as an associate to the pratice. Then I went on to purchase my own dental practice in Santa Ana, California where I have remained until this very day, over thirty -three years. My wife and I have three grown children and seven grandchildren; we consider ourselves very blessed and spend as much time with our family as we can. As for my career, I am an extremely fortunate man. I love being a dentist, and I believe my patients know this based on my commitment and devotion to them, their family members, and/or neighborhood friends. My ultimate goal is to offer quality dental work for affordable prices. Everyone who comes to our office can count on our honesty, our respect, and his or her thoughts and feelings being taken into consideration. I operate a smaller size dental practice that employs a staff of combined full time and part time employees some who have been with me for three decades and others who have been with me three to five years. Together we comprise a dental office that works hard to make sure that our patients leave happy and with a great smile.
