Our family has been going to Dr. Duran for years now, and I wouldn’t go to any other dentist. We are treated like family, contacted promptly with updates or schedule changes, and they are always willing to work with me. Dr. Durans work is painless and I have never had any problems with the work he’s done! And BEST STAFF EVER! They’ve all been there for years with each other and they operate like a fine oiled machine!! LOVE DENTAL HEAVEN!

Took my son to get his two bottom wisdom teeth extracted last Friday, Dr Duran did a fantastic job! My son was very nervous but Dr Duran & his staff made him feel very comfortable. During the procedure he felt no pain & was listing to his headphone the entire time. Since his wisdom teeth were impacted, he had minimal swelling & little pain (after the numbness went away) but once he started taking his meds he was feeling great! Went back today to get his stitches removed & both of his gums where the wisdom teeth were pulled out look amazing! Thank you again Dr Duran you have a way with making everyone feel comfortable! We will be back soon.

Recently had oral surgery at dental heaven. I was extremely nervous and scared. The office offers nitrous oxide and the Dr. Is very comforting. I didn’t feel a thing and was happy with the results

Outstanding dentist and staff. My entire family goes to dental heaven. We have been patients since 2002! I love dr. Duran and his staff and I REFUSE to see another dentist……insured or not! I guarantee u my dentist is the best one around!!!

Nelson S. from Upland, CA (Source: Yelp)


Had a broken tooth that needed a root canal. I was really concerned about the pain and treatment. My first visit was to do X-rays and to pin point the damage. This was painless and very straight forward. The monitor is right in front of you so you can see all of the images.  Next appt. The dreaded Root canal. Lol… Dr.Duran was AMAZING!!! I did not feel anything. Not even the needle to numb my gums. I had ZERO pain. After the numbness wore off, I still didn’t have any pain. I’m a 51 yr old male. Let me just say I found my dentist for life. I’m not exaggerating.

This place is amazing! From the intial visit the staff are wonderful, if your cold they have blankets, if you are nervous ether have options which really work for you and very affordable. That’s just the beginning, the dentist makes sure your teeth are beautiful and healthy. I would recommend them to anyone

Mariel B. from Rancho Cucamonga, CA (Source: Yelp)


Came to get cleaning done. Very happy with staff and Dr. Duran. They took X-rays and pictures to show me exactly were I had cavities! No other dentist had taken the time to show me before! Very happy I can tell they care about my oral health and not only my money! Thank you Dr.Duran!

Andre L. from Rancho Cucamonga, CA (Source: Yelp)


Just want to say to anyone out there searching for a dental office, this has been the best place for me.  Dr. Duran and all the staff are wonderful! They will work with you to help with your dental health.  I have extensive problems due to my age and other factors and they found a way to help me out.  Don’t hesitate to call them or even to stop by in person for any questions you may have.

Kim C. from Rancho Cucamonga, CA (Source: Yelp)


Everyone here is so nice and proffesional. As soon as you walk in they greet you with a smile and when they are working on you they do it with such care and sensitivity. I didn’t really enjoy going to the dentist until like 2 years ago i came to Dental Haven. I really recommend coming here and bringing your kids.

Andrew I. from Rancho Cucamonga, CA (Source: Yelp)


Dr. Duran and his staff make the dentist an enjoyable visit. I was absolutely terrified of the dentist so much so that I did not go for over a decade. Dr. Duran and his staff completely changed my outlook on dentists. Of his staff, Cheryl, Diana, and Jennifer all played their parts in making it a wonderful experience. The best part is they all make you feel human. They obviously take great pride in what they do, and their teamwork shows. No pain at all, they make you feel comfortable in the chair, and it’s over before you could start to worry about the fact you’re at the dentist. Overall, if you are worried about the dentist, I highly recommend this awesome practice. I cannot wait to go back and finally have healthy teeth. I would give them 6 stars if I could.

Eddie C. from Lancaster, CA (Source: Yelp)


Best dentist I’ve been to. I come from pretty far away about 2 hours just to see them. They have the best people working there so friendly and nice. Always working with me and accommodating my busy schedule.  I would really recommend anyone trying them at least once you won’t regret it.

I just had my initial appointment but will update after all my treatment. First I’d like to say that I have severe anxiety and anything to do with teeth is at the top of my list. When I called when a bunch of unusual nervous questions I was answered kindly and patiently from Jennifer. The lady (didnt catch her name but will find out) at the front desk is so kind. She played with my son and was so helpful. Taking x-rays and photographs was painless and efficient. Dr. Duran was thorough and quick. I have an entire treatment plan set up with the different options from Jennifer. The kindness and professionalism really makes me at ease on top of the option for nitrous to help ease my worries. Looking forward to being problem free in my mouth.

I have the worst teeth ever!  So of course I have spent a lot of times in the dentist chair.  Just thinking about it makes my blood pressure go up.  I fount Dental Heaven about 4 years ago and I absolutely love them!  Dr. Duran, Sharyl and Diana feel like extended family.  Because of the covid 19 situation they are only open for emergencies, of course I had one.  They got me right in.  They only have one seat available in the lobby.  Have you keep the pen you sign in with and are all completely geared up.  If you are looking for a superior dentist and even better staff look no further!!!  Thank you Dental Heaven for taking such good care of me

I first visited dental heaven 18 years ago and went in a few times,d unfortunately my insurance changed and they were no longer in my network. I recently went back to see doctor Duran and his staff and I was greeted with the same warmth that I remember from 18 years ago. Dr. Duran is extremely personable and honest. His dental work and knowledge are both impressive. I’m happy I’m back…. Looking forward to the next 18 years

Jennifer P. from Rancho Cucamonga, CA (Source: Yelp)


My son and i have been coming to Dental Heaven since 2011. Dr Duran and his staff have always been friendly to my son and and I .They work with you financially and do amazing work. They are also really good with kids. I always recommend them to my friends and family. I couldn’t imagine going anywhere else

Wish there were 10 stars I could post! Top quality Dentistry, patient, kind. Dr. Duran takes his time, discuss your treatment and Expectations. From the minute that you get there at the front desk you know you’re in the right place, staff is superb. I have the highest highest anxiety going to the dentist and they have made it so easy and comfortable for me to keep returning Dental heaven.

Dr. Duran is very good at what he does and has the lightest touch of any dentist I’ve ever gone to. His thoughtful and deliberate approach to my procedures (and there have been a lot) has made me a lifetime patient.

Johnathan A. from Rancho Cucamonga, CA (Source: Yelp)


I really love this place. I’ve been here so many times and had the best experience ever. The nurses are all the kindest and Doctor there is amazing at his job. Any problem you have he can handle. I give this five stars and recommend it for everybody

D. C. from Rancho Cucamonga, CA (Source: Yelp)


All of my life I have had very negative experiences at a dental office. Enough about the past let me brag about Dental Haven. First call I was greeted by Diana (love her energy) She immediately made an appointment for me and was in within the week. Wow!! They are so organized and friendly. When I came in I was greeted by the same warm welcome. I’m not going to lie I was still a bit skeptical. I mean it’s a dental office all they want to do is take my teeth and money like all the rest of them, right?? NO not at all!!  Gosh, Dr Duran named his dental office perfectly. Dental Heaven, it really is Every time I’ve come here I feel so comfortable and at ease. Never have I felt that way at another dentist ever. With all the work I’m getting I’m happy to sit on the “hot seat”. the entire staff is so genuine and helpful. They are happy to answer any questions or concerns I have. I am super grateful to have found Dental heaven.

I’ve gone to this dentist for about 2 yrs now, probably the best experience over the last 10 years with several other dentists. Honest, good customer service and great work/results…so far. Highly recommend.

My family of 6 have been going to Dental Heaven for 8 years and they have been so wonderful!  The entire staff is friendly, and Dr. Duran is amazing.  Dental Heaven takes the fear out of going to the dentist.  My kids actually want to go!  Four of us have gone through the orthodontic program, as well.  I would never want to take my family or myself anywhere else.  Thank you, Dental Heaven!

Excellent experience! Staff very friendly, and doctor always take good care! I have been a patient for 9 years! I would definitely recommend!

Letty X. from Victorville, CA (Source: Yelp)


I have two little boys (age 3 & 7) who LOVE going to the dentist because it is heaven! The Doc always makes my kids feel safe and comfortable.  He takes the time to explain all procedures and recommendations not just to me but to the boys as well. He shows them all his cool gadgets and always sends them off feeling great about their smile. The staff is awesome as well. They are professional,  kind, and also very funny. Although they only see us twice a year, they never forget my boys. On our last visit, the nurses surprised my son by wearing silly glasses with a plastic nose during his check up.
I highly recommend Dental Heaven

I hands down have never liked going to the dentist. I get a lot of anxiety going in and getting procedures done! But here at Dental Heaven, the staff and, even the doctor, are so nice and so gentle!! And they don’t push extra charges on you, trying to make extra sales. They explain things so well and make sure you understand the procedures getting done. I highly recommend them!

Onna H. from Corona, CA (Source: Yelp)


Been going here since I was a small young child probably around the age of like 7. I was literally terrified of the dentist. I went from Loma Linda Children’s Dentistry to Dental Heaven’s office. Up until I met Dr. Duran I would cry as a child & panic but when I started coming to Dental Heaven Dr. Duran made me feel so calm & relaxed. Dr. Duran was patient with me and have always treated me so kindly. The staff is like a family & I always feel welcomed & right at home. Would not see myself going anywhere else. Dr. Duran is very knowledgeable and up to date on all medical practices and procedures. I have never encountered any issues throughout the many years I’ve been going to Dental Heaven. I definitely will be bringing my children to Dr. Duran when I have some in the near future if he is still practicing.

Omg !! I had a toothache for 2 weeks straight and didn’t want to be bothered with a dental office . Finally I couldn’t take it anymore so I did my research and ran across dental heaven and I must say I don’t regret it AT ALL . My first visit which they called an emergency exam only concentrated what was bothering me . Boom three days later Dr. Duran had that taking care of . He pulled my tooth without any pain or discomfort. If I felt any source of pain he stop and numb me again . This office really care about you as a patient and not just your money and I’m forever thankful for that . I would recommend anybody to go here. I go back next week for full exam and check up .
