I've been seeing Dr. Quinteros for over 14 years, which speaks volumes about the trust and confidence I have in his work. During this time, he has performed various procedures on me, from wisdom tooth extractions and x-rays to cleanings and cavity treatments, always with the same dedication and professionalism. What I appreciate most is how clearly and simply he explains each step of the…

process, using technology that makes it easy to understand the diagnosis and treatment options. He also always provides preventative recommendations that help maintain long-term oral health. His immediate availability is another great advantage, as it gives me peace of mind knowing I can always count on him. Without a doubt, I recommend Dr. Quinteros and his team for their professional excellence and the trust they inspire through their personal approach.

I've been seeing Dentist Quinteros since I was a kid. I put the cap on once and it was amazing... 100% trustworthy.

I went to this clinic because the care is excellent, the prices are tailored to each patient's budget, and Dr. Juan Quinteros is a sweetheart with his patients. The staff is great, I recommend it.

I've been attending Dr. Quinteros' clinic all my life. I started with the father and now with the son. It's more than a professional relationship; I feel protected by the team of professionals.

I'm sharing my experience at the Quintero Rancagua clinic. The care is superb. The doctors are very kind, and the entire medical team is very caring. My husband and I got implants, and they've worked incredibly well. I recommend the Quintero clinic 100%.

I went to get a cavity removed (which wasn't painful yet). It turns out they didn't remove it completely, and I had to go back two months later because of pain in my filled tooth, but now: for a root canal. Okay. I'm getting the root canal, AND I HAVE TO GO BACK because the doctor (a Cuban one) performed the treatment incorrectly. All because of a cavity I went to have removed responsibly before…

I had an accident, and after visiting several clinics, I ended up here and had a great experience. From the first day, the secretaries were very kind and dedicated to each patient. Not to mention the first-class professionals. This clinic has the latest technology and everything is top-notch. I've recommended it and have been very satisfied. Thank you for everything you did for me. I would…

Hello, I was seen by Dr. Quinteros, a professional, empathetic, concerned about the patient, and he explains everything clearly.

My wife was treated rudely by one of the dentists; he was in a disrespectful and vulgar manner. Dr. Juan P. Arenas
Ana Maibee via Google 5.0 out of 5
I want to share my experience with Dr. Juan Quinteros' dental clinic at Bueras #20 in Rancagua. I had an implant for many years and went to his clinic to have it replaced. I was referred to Dr. Juan Pablo Arenas, an excellent professional with great compassion and respect. I highly recommend the clinic for its quality and cutting-edge technology. Many thanks to all the staff.
C.E via Google 1.0 out of 5
Terrible service. Due to a botched procedure, I lost four teeth (the two upper front teeth and the two upper canines). They never took responsibility for anything, not even an apology. And don't even get me started on the owner of the clinic... when her father ran it, the service was much better, but now that it's in his daughter's hands, they do whatever they want with the patients and don't care…

if you sue them. DO NOT GO TO QUINTEROS DENTAL CLINIC. A LARGE PART OF THE STAFF ARE RECENTLY GRADUATED YOUNG PEOPLE WHO WILL MESS UP YOUR TEETH (THEY LEARN BY US).

Hello, I went yesterday for toothache and I was surprised by the attention from the person who made my appointment over the phone to the humane and empathetic manner of each of the members who participate in this clinic. Furthermore, it has great technology and is affordable. But I recommend it. Now I just hope to recover from the extraction of my wisdom tooth, which was taken out the same day.
Polett Espindola via Google 1.0 out of 5
The service from Dr. Pablo Olate, brother-in-law of Dr. Quinteros, was terrible. I had orthodontic treatment with him, and he didn't do a good job. I say this because I consulted several clinics for other opinions, and they all said the same thing. Dr. Olate is unethical; he only cared about the money. Every time I went, I told him I had a problem with a tooth, but he ignored me, and now it…

t seems I'll have to get a root canal. The day came to have my braces removed—I'd had them for a year—and he was extremely rough about it. He left traces of glue or whatever they used to attach them, and the first thing he asked when I walked into the office was, "How much money are you bringing?" All he cared about was MONEY. He always rushed things, was very careless, and didn't explain your case or the procedures. If you didn't notice he'd forgotten to put an elastic band on, he'd just let it slide. That's how careless he was. He'd finish a 15-20 minute appointment in 5, doing everything haphazardly. So, from the bottom of my heart, DO NOT GO TO THAT ORTHODONTIST.
