Searching for a good dentist recently has been a problem for me so I thought I would give online reviews a try. I was worried about going to find a new dentist because the last place I went was a disaster. I needed a dentist in Rancho Cucamonga so I searched review sites and saw Baseline Dental had great reviews so I decided to give them a chance. I had the same experience as the reviews I read. When I went there the front staff and everyone was really friendly. I saw Dr. Buck who was very thorough and explained the things I needed. The last place I went said I needed a lot of work done and didn’t explain why. Dr. Buck said I needed less than half of the work the previous dentist said which is about what I expected in the first place. He also explained why I needed a crown and showed me on the x-ray why. When I went back for my cleaning they did such a good job. My last two offices I was in and out in like 15 minutes for the cleaning and it felt like they did nothing. At Baseline Dental the hygienist took her time and did a really good job cleaning my teeth. I have had such bad experiences at other places but here you just feel like you can trust them. I’m so glad I’m going to Dr. Buck now. To top it all off they gave me a gift bag as I left. I will be telling all my friends. Thanks for everything.

I have been a patient at Baseline Dental Practice for over 10 years. It is the best dental office I  have ever been to. I usually only go for my 6 month check ups with my hygienist, Simone. This time I needed a small procedure with Dr. Buck. He listened to my concerns and was very gentle. I hardly felt a thing. Everyone at this office is friendly and they treat you like family.  Thanks everyone at Baseline Dental!

Frankly I’m bummed that Yelp doesn’t give 10 stars because that’s what I’d be giving Dr. Buck!  He’s fantastic!  He and his staff are so friendly and supportive.  So here’s the scoop.  I haven’t gone to the dentist in a while… AKA 8 years.  I know, I’m terrible, don’t judge.  My last dentist was a little rough and left a bad taste in my mouth…literally. But after 8 years, I knew the time had come for me to be a man and face my fears.  So I called Baseline Dental and made an appointment.  Dr. Buck was so kind and soothed my troubled heart.  After inspecting the war zone in my mouth, he discussed a plan of how to tackle these problems…together.  The strategy involved me setting multiple appointments and then… showing up.  Then, with his radiant personality, his extraordinary skill set, and the use of the brilliant laughing gas, we went to work.  Everything went so smoothly.  It was excellent.  I feel like I should be the poster boy for Dr. Buck because I gave him so many wonderful problems to solve.  Almost as if my mouth was created to fulfill his destiny. Anyway, after multiple cavities filled, root canals, extractions, and gum cleanings, I’ve learned two very important lessons….Dr. Buck is the Man.  Don’t fear the Man.  Go see him….every 6 months if possible. I probably should floss more

I have been a patient of this practice for over 30 years. Unfortunately, the service is more about the price per head than the patient care, of late. I will be pursuing another practice where I am not just a number. Too impersonal. Didn’t used to be that way, and sadly, isn’t where I want to be.

Dr. Buck was friendly and professional. My wife had 3 teeth that needed work. We had visited multiple other dentists that were cold and uncaring. I got an appointment quickly, did not wait long and was in and out in a little over an hour. I cannot recommend a dentist more highly. If you want to be treated by a dentist that cares and does good work, go see Dr. Buck

Maricela S. from Rancho Cucamonga, CA (Source: Yelp)


Everyone in this dental office is attentive from the front desk, to the dental assistant, hygienist , and doctor Buck is really nice, funny, gentle and  makes you feel super comfortable by explaining procedures

Carlos E. from Rancho Cucamonga, CA (Source: Yelp)


Doctor Buck was honest and did excellent work. All the staff were very informative of all the work I would be needing and would run through all the costs. Definitely would recommend. Michelle and all the other front desk girls were super caring in getting all my work done in a quickly fashion! It’s hard to find this in a dental office but this one had it all 🙂

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


Wow! Who would have ever thought you could leave the dentist’s office with such positive feelings?? I could not be more pleased with the care my son received at Baseline Dental. From the minute we walked in the door, the friendly hellos from multiple staff members assured me we were in the right place, but the care from the dental assistants and dentist sealed the deal. My son commented when we left that he would never have any nervous feelings about going to the dentist if we had always come to Baseline Dental… and he had a root canal!! Thank you to everyone at Baseline Dental for a great experience. We didn’t always go to Baseline Dental, but we definitely will now!

A place that makes you like going to the dentist.  Come here and you won’t be disappointed.  I’ve been coming here since I was a small child and I will never go anywhere else.

Alyssa F. from Rancho Cucamonga, CA (Source: Yelp)


I had to do a filling and it was honestly the best experience I’ve ever had with a dental office. Dr. Buck was super nice and thorough. I could tell he really cared about my comfort. The dental assistant theresa was super sweet and made me feel at ease. I look forward to my next experience with this dental practice

Daryl D. from Ontario, CA (Source: Yelp)


Great Dental place! Just started going here and the staff are amazing, very kind and welcoming! This is the first dentist where I did not feel “pushed” into trying to have something done. I’m very happy with this dental spot and will be staying here

Lindsay M. from Bloomington, CA (Source: Yelp)


I came in to see Dr. Buck for a tooth infection & extraction. Himself, as well as his staff are incredibly professional and polite. Dr. Buck eventually referred me to an oral surgeon to complete my treatment and even the surgeon he referred me to was a God-send. I’m super grateful for my treatment at Baseline Dental & thankful to the awesome doctors and staff for treating me so gently & so well. I appreciate them very much and would highly recommend this practice to anyone

Doug J. from Loma Linda, CA (Source: Yelp)


Dr. Buck is OUTSTANDING! I took my granddaughter there to have four wisdom teeth pulled. She was a nervous wreck and so was I. From the moment we got there, everyone was so kind and comforting. Dr. Buck took care of the teeth, and my granddaughter was amazed at the lack of pain and discomfort she experienced. He was even great at soothing the grandfather. Thank you Dr. Buck for being a compassionate, talented dentist

Yaima M. from Rancho Cucamonga, CA (Source: Yelp)


My whole life I have been scared of the dentist, as many people are; but, my prior experiences have been more than just unpleasant. I’ve dealt with many dentists who have taken the more expensive route to a solution, or even straight out lied to me and recommended procedures that were unnecessary. Needless to say, I don’t trust dentists. Until now. Dr. Hernandez treated my mom after she received a crown and her dentist was not available. They are open Saturdays, which is amazing, and with little wait and little paperwork, my mom was in the chair and on her way to relief. She was treated with respect and the utmost care. Thankfully, the pain she was experiencing was cured with a little drilling on the crown, and she was on her way. No gimmicks, no smoke and mirrors, it was a simple procedure and it was handled with grace and in a timely manner. Since that day I have been a patient of Baseline Dental, I have dealt with both Dr. Buck and Dr. Hernandez, they are both amazing. The staff is friendly, welcoming and knowledgeable.  Baseline Dental has integrity and most importantly, they care about ME. I would highly recommend. Tip for parents: for your kids (or yourself) they also have a pokestop at the practice! 🙂

Entire staff is great! I never liked going to the dentist, who does? But I started going here in November to finally catch up on some long over due dental work.And I don’t regret picking Baseline dental. Every person at this location is professional and pleasant…. highly recommend Baseline Dental

Kathy J. from Rancho Cucamonga, CA (Source: Yelp)


Dr. Buck thank you for your care and the nice surprise of charging only for the X-ray.  I have been a patient at Baseline Dental for over 25 years. You are a wonderful addition to a wonderful staff. Please know that what you do makes a difference in the life of others.

Stella R. from California (Source: Yelp)


I’m SO happy I came to Baseline Dental Practice. Dr. Buck is a phenomenal individual, and the staff are amazing. Dr. Buck is super cool, compassionate, down-to-earth, genuine, and a great listener! He explains everything thoroughly, and answers all my questions and concerns. I feel safe in his hands! I recently got my wisdom teeth pulled, and Dr. Buck was super gentle, and I appreciated that SO much. I had a bad experience in the past with another dentist who removed my bottom wisdom tooth, so it took me a while to feel ready to get my top wisdom teeth removed. I was a little nervous, but the whole process was SO smooth, and recovery has been a-ok! Office is clean and peaceful! Did I mention the staff are amazing? (: Highly recommend Baseline Dental Practice

Everyone in the office is so friendly and willing to help you. I’ve been going here for a year and was the best decision I’ve made was coming to this office. From the dentist to the ortho, they’ve been amazing!

Marcella M. from Ontario, CA (Source: Yelp)


Dr. Buck is the best. A friend recommended baseline dental to me and now I’m all set up. Receptionists are so friendly and helpful which makes the whole dentist going experience less stressful.

Ashley A. from Garden Grove, CA (Source: Yelp)


Love Love Love Baseline Dental Practice! Service is prompt, scheduling and booking appts are NO HASSLE! Dr Buck is very informative, gentle and he is the go to dentist for me! Thank you to Michelle, The Beautiful Blonde Dental Assistant & to Baseline Dentals Team!!!!

Alicia G. from Rancho Cucamonga, CA (Source: Yelp)


I’ve only come in twice so far, but each time I do, I’ve had the most pleasant experience. I don’t dread going to the dentist anymore! Everyone here is so friendly and both the dental assistants and dentist are super gentle and caring!

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


I am so pleased with my appointments this far! This office has the feel of a private practice office to it… very warm and inviting. Dr. Buck was great! Their X-ray tech was very good and their orthodontist Dr. Firoutz was awesome. The front office staff was very friendly and accommodating as well. I have a feeling this will be my dentist office for years to come

Freddy G. from Corona, CA (Source: Yelp)


I was unhappy with my previous dentist, so I came to baseline dental to get a second opinion on some work I needed done (dental implant). All of the staff up front were warm and welcoming. The dentist was on time with my scheduled appt which is always a plus. When I got to the back, Dr. Buck clearly explained everything that was going on in a simple, easy to understand way. He was friendly, thorough and let me know all of my options. Not only that, he let me know what to expect during and after the visits to eliminate any fears or hesitations I had. Their quote came in at almost $1000 less than my previous dentist as well! I’m glad I picked Dr Buck and Baseline dental for this dental implant I need done. I had such a good experience that they’ll be my primary dentist going forward

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


Love this place. When you first walk in you are greeted with smiles and a hello. Everyone at the front desk is nice and Welcoming. The hygienist and assistants are great. The dentist are great. I would recommend this office to everyone. I use to be very fearful of dentists but they really put my mind at ease.

TJ. S. from Southern California, CA (Source: Yelp)


The staff is always friendly and welcoming – I was even informed 40 minutes before my appointment that they were a little bit behind, and I that should come 10 minutes later than the original appointment time. They do a great job communicating; they call to confirm appointments, they remind if one hasn’t made and it’s overdue, etc. The work done is always quick, efficient and an all-around pleasant experience. Parking is always available and close to the door. The waiting room is never full. Open on Saturdays?! Very nice not having to take time off from work or school etc. There’s nothing here to complain about. Always satisfied with my experience!

LaRhonda R. from Rialto, CA (Source: Yelp)


Very nice & clean dental office. Receptionist & staff are very kind. Dentist has the most gentle hands and very concerned with your comfort when working in your mouth. Hands down! Never had an issue with prices either. Great job Dr & staff. See you in 6-8 months!

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


I am not a fan of dentists; but we all need them. I’ve known Dr. Buck personally for over 10 years and always admired his work ethic. He continues to work hard as a dentist and it shows. I’ve seen him show how much he really cares for people and he continues to deliver the same care for his patients. With Dr. Buck, you are not just another number, you are his patient. The office is spacious and the staff is friendly. Thank you Dr. Buck!

Love everybody here! Everyone is super nice, which makes going to the dentist more enjoyable I would and I do recommend baseline dental !!

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


My favorite dental office. The ladies at the front are always welcoming. I have seen Dr Hernandez for many years and for a variety of dental work: root canal, crowns, and he is an exceptional dentist-caring, gentle, and competent. I trust him with my dental needs and I also take my daughters here. Dr Buck is also very kind and  gentle and I would recommend him as well. All the hygenists are great; I always leave with my teeth feeling clean and I appreciate their positive attitudes and the way they provide exceptional service. I would highly recommend them with confidence

Took mi kids and they even said they loved this dentist after having other bad experiences at other facilities. The staff is very nice and friendly!

Kelly G. from San Bernardino, CA (Source: Yelp)


I could go to other dental practices that my take my insurance, but I’ll pay cash just so I can go to Baseline Dental. Dr. Buck is such an amazing dentist with the best staff, and I feel at ease knowing my family is getting the best care. Rest assured when you go to Baseline Dental your teeth are in the best hands possible!

Yaima Montes de Oca (Source: Facebook)


As someone who is afraid of the dentist I naturally avoid it, but with Baseline I feel comfortable. They are considerate, honest, and great at what they do! Thank you Baseline!

Lizette V. from Downey, CA (Source: Yelp)


My husband and I just recently moved closed to the area. So it was time to look for a dentist, since its been a while since we both seen one. Had my first consultation today and the service was so great. The placed is very cleaned and everyone is very professional. They make you feel welcome.  I would highly recommend this place.

M. T. from Rancho Cucamonga, CA (Source: Yelp)


Fast, honest service. Did my dental work as well as my kids, Im surprised they do not specifically advertise that they do children’s dental. Dentists did an awesome job with my kiddos.  front office is great as well!

Erin U. from Rancho Cucamonga, CA (Source: Yelp)


I definitely recommend this dental office. I was in pain, so I called first thing this morning. I had never been there before, but they were still able to get me in today. Everything about my experience was great. I felt like the staff was friendly, personable, & professional. They were able to work with me with all my insurance stuff to make sure I wasn’t paying unnecessary expenses. If you are looking for a new dentist, you should check this office out
