I am extremely disappointed with the care I received at Barosum Dental in Upland. My experience…read moreleft me feeling unheard, misdiagnosed, and ultimately traumatized. While I was out of town on July 12, 2026, I developed severe pain on the lower right side of my mouth. As soon as I returned, I scheduled an emergency appointment for July 15. I also had a previously scheduled deep cleaning appointment for July 16. During my emergency visit, the female dentist appeared to minimize my concerns. Instead of focusing on the area where I was experiencing pain, she asked whether I had seen an endodontist for a referral from a year earlier and questioned a shadow in my gums that had existed for over 30 years on the opposite side of my mouth. I requested X-rays, and a 360-degree scan was performed. After reviewing the images, she told me everything looked fine, that I had no cavities, gave me Sensodyne toothpaste for tooth sensitivity, and said I was cleared to proceed with my deep cleaning the following day. Later that same day, the office coordinator called and told me they wanted me to see the endodontist before my cleaning. I went to the appointment, and within five minutes the endodontist identified a cavity. My primary dentist confirmed the finding and recommended that my wisdom tooth be extracted. I was extremely upset that my condition had been missed during my emergency visit. I asked to speak with the female dentist who had evaluated me, but she was unavailable. I scheduled the extraction for July 17, 2026. Because I had previously had a successful experience using nitrous oxide during another tooth extraction, I requested it again to help manage my anxiety. I was numbed for the procedure and was told I was receiving nitrous oxide, but I never felt its effects. I noticed the dental assistant was on the phone for much of the procedure, and it appeared that no one ensured the nasal cannula was properly positioned. I informed both the oral surgeon and the assistant that I did not feel like I was receiving the nitrous oxide, but my concerns were dismissed. I remained anxious throughout the procedure, and the extraction was ultimately unsuccessful. I left the office emotional, traumatized, and deeply disappointed. This was the worst dental experience I have ever had. As healthcare providers, listening to patients is essential. I repeatedly expressed my concerns and felt they were ignored every step of the way. I will not be returning to this office. I also plan to verify that my insurance was not billed for procedures that were not completed, including the deep cleaning and the unsuccessful tooth extraction. I hope this review encourages the office to improve communication, patient care, and attention to patient concerns so that others do not have a similar experience.

I looked on…read moreYELP to see more reviews on my previous Periodontist, Dr. Daniel Gardiner and there weren't any recent reviews for him and his office. Just wanted to let you know that prior to my move, I had been coming here for over 20 years! Cherie was my hygienist and throughout those years, we had a sweet friendship there as we both are moms of boys, now men! Dr. Gardiner is a sweetheart and a very thorough dental professional. I was referred to them by my dentist, Dr. Janet Churella, DDS of Chino (RIP) due to my gums receding way in the late 1990's. After years of brushing with Extra soft toothbrushes that this office had provided me, my gums have no longer receded further thanks to my bi-yearly check ups here. Sure do miss the sweet staff there who were always so accommodating when I was late to my my appointment due to my forgetfulness or the traffic. They were like family! There should be many more recent reviews here on YELP for Dr. Gardiner and his staff so I am on here to let you know that this periodontist and his staff are the best I have had!

We are incredibly grateful for the care my husband received and would highly recommend this oral surgeon to anyone needing oral surgery or any of his services. It is reassuring to know that there are still doctors who combine exceptional skill with genuine compassion. Five stars all the way!

The dentist I saw then, I have not seen again, but she was amazing, especially during a very stressful experience of having to have a tooth removed thanks to a horrible previous dentist. i am one of those who hates going to the dentist, but when it comes to coming here, its not so bad. Since that experience, I have been seeing Dr Guevara. He is AWESOME. First dentist I ever met who talks me OUT of spending money and going through painful dental surgeries. That alone really develops trust for me. I've had a need to have some cosmetic work done which I have put off for years because it takes time to build that relationship and trust that they are truly helping me versus lining their pocket. We discussed my needs and developed a plan together. I'm a little phobic still, but Dr. Guevara puts you at ease with conversation, jokes and he's actually really interesting to talk to and is knowledgeable in many subjects. I get my cleanings here and have had a crown made since my initial problem and I am truly comfortable and happy coming here for my dental needs. I have no idea who Greenway is, but Dr Guevara is fantastic and you could not ask for a better, more trustworthy dentist.

When I first called them, the front desk lady Christine was very helpful and friendly; so I decided to give it a try. I was not disappointed, everyone in the office was just as nice and helpful. Dr. Kao spoke very patiently, took his time and explained his diagnosis and treatment. Office manager Lisa was also a down to earth and interesting person to chat with. Overall, they gave me a small and family-like feeling, which is rare for a dental office. (Especially coming from a massive place like Western)

When I asked the front desk for an estimate, I was told "10 minutes," which turned into another 30 minutes on top of the long wait. When the dentist finally came in, he did not greet me, introduce himself, or explain anything. He came in grunting, immediately grabbed my bottom lip with force, and said "lots of tartar" -- which I already knew, that's why I scheduled the appointment. He then walked away to see another patient. Meanwhile, he spoke politely and attentively to the next patient, asking her about her concerns -- I was never asked how I was feeling, what my symptoms were, or anything about my pain. After this brief interaction, the dentist never returned. After nearly three hours in the office, I was told no treatment would be done that day. I was only given a prescription, and even that was communicated indirectly through the assistant while he was in the room. This experience felt dismissive, disrespectful, and completely unprofessional. Patients deserve basic courtesy, communication, and consent -- none of which I received here.
