Dr. Amin is an experienced, kind, and compassionate doctor. I never feel rushed, as he takes his time to do a thorough exam and answer questions. He and his staff always make sure I feel safe, comfortable, and have a good experience. The office environment is inviting and spotlessly clean. He utilizes the latest equipment and practices strict safety and sanitation procedures. I highly recommend Dr. Amin and DNTL studio.

Since the time of Dr. Desai making a special appointment to evaluate my emergency situation outside of regular business hours and providing a solution a few years ago I have been working with DNTL for all of my dental work. The staff at DNTL has been taking excellent care of all of my dental needs. If you are searching for a great dental office I highly recommend checking out DNTL.

I have been coming to this dental office for years. I can't say enough about Dr Amin, Julie and absolutely EVERYONE in this office! They care genuinely about you as a person and patient. Dr Amin is gentle, caring and his technique is outstanding! As is all the care I've ever received here. Come here as a patient and you'll see what I mean!

I recently visited DNTL Studio and was thoroughly impressed. The office was clean and inviting, creating a calming atmosphere. The staff were polite and attentive, making me feel comfortable throughout my visit. The hygienist, Chelsea, was very gentle while taking my X-rays and ensured a pain-free cleaning. I appreciated the range of treatment options provided. Dr. Amin and Dr. Desai were both skilled and professional, and I left feeling extremely satisfied with my treatment. I highly recommend DNTL Studio for anyone seeking quality dental care.

The absolute best dental office I have ever visited. Dr. Amin and his staff are extremely thorough and take the time to address any and all concerns a patient might have. Julie gave me the best cleaning and oral health consultation I have ever received. I left the office feeling so taken care of and strongly recommend them to anyone in the area.

I have been a patient at this practice for a very long time. When the previous owner, Dr. Bahri, retired, Dr. Desai and Dr. Amin took over and seamlessly integrated themselves into the practice. I have been consistently pleased with the care provided by Dr. Desai and Dr. Amin, as well as the entire staff. The team is incredibly friendly and welcoming, from my teeth cleanings with hygienist Julie to my dental work with Dr. Desai. Assistant Rossana and receptionist Ani, along with all the other staff members, are always attentive and make me feel like a valued patient. I am grateful to be a part of such a great team and highly recommend DNTL Studio.

DNTL was able to schedule an appointment for for me the next day after I broke my molded which was an emergency for me eventhough I was not a client. Dr Amin. was able to complete dental procedures during my visit and he was really gental and explained complete procedure from being to completion. All of DNTL Team were very professional and nice during my experience. I have found my new dental studio and will refer anyone I hear needs a good dentist as I am 100% satisfied!

I've been coming to this office since 2006 & remained a patient when Dr. Amin & Dr. Desai took over the practice. I've been thrilled with their work and so happy that Dr. Bahri left the practice in great hands! All the hygienists are extremely kind and welcoming as well. I now live in San Diego and still make the drive to Upland twice a year for my dentist appointments because I don't trust anyone else!
