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.

The check in process was smooth however what happened after is what was disappointing. Dr.Morales was a terrible doctor and was very unkind. The hygienist was great so I decided to come back. I was happy to hear that Dr.Morales was no longer there. I refused to have x rays done again since we had billing issues before. They let me get seen but said next time I'd have to do them. The cleaning with the hygienist was good. I paid out of pocket for some services not covered but was disappointed that after the appointment I was charged more money. They're fraudulently charging insurance. I gave them the benefit of the doubt and called to get an explanation and was told I would get a call back. Still waiting for that call for over a month. Then today I get another bill. FRAUDS! Do not go to this dentist office. If they have any good reviews I am sure they were persuaded with something to do so.

Rose in the office also was VERY neglient on calling for her crown. It should have been weeks from the time she got her root canal to the time she got her crown. NOPE. After months of pain, calling the dentist they finally made an appt and the Endodontist said her tooth was UNSAVABLE and she had to get it taken out!!!!! So she lost her permanent tooth and of course they wanted her to get an implant. Her other root canal never got a crown either. After months of waiting for it , on the day she was suppose to get her crown Upland Dental cancelled her appointment and said they could no longer see her!!! These people are the most unprofessional people/business I have ever seen. They wanted to do thousands of dollars of unnecessary stuff of which I said "No we will just get necessary things done first. Wow, FRAUD ALERT.

From the moment I walked in, everyone was friendly and welcoming, and the office was extremely clean. My dental hygienist, Teresa was fantastic!! She showed me around, gave me a full cleaning, and actually took the time to explain how I could better care for my teeth. She taught me a lot about the benefits of using a soft-bristle toothbrush to help protect my enamel and gums. She also shared her personal routine of using a soft-bristle toothbrush in the morning and an electric toothbrush at night, which was completely new to me and made a lot of sense. Another cool touch is that they have TVs mounted on the ceilings above the dental chairs. I've never seen that before, but it definitely makes lying there with your mouth open for an hour a little more enjoyable. The doctor also seems genuinely invested in new technology and innovation. The office has all kinds of impressive equipment, including in-house 3-D printing machines. It felt more like a modern dental lab than the typical dentist's office with one sad fish tank in the lobby. I will absolutely recommend Smile Studios and will 100% be coming back.

I want to start by saying this is going to be a long one but please read to the end…read more I've been coming to Smile Studio for the last 4 years and let me tell you, they have completely transformed my smile. My first visit was very emotional and I was embarrassed and angry with myself for letting so much time go by without visiting the dentist. I am so grateful for Teresa, my dental hygienist who let me cry on her chair and reassured me I was not alone and it was going to be OK. I started periodontal treatment and saw instant results. I had routine cleanings every 3 months and after about 9 months when my gums were healthy again we had the conversation of braces. Not only are Dr. Ra and all the dental hygienist amazing but so is Dr. Dacker and the ortho team! They always worked around my periodontal cleanings to ensure my treatment was never compromised. It was not always easy to schedule cleanings on ortho days but they would move schedules around and do anything they could to make it happen and I am so thankful for everyone's efforts for the 2 1/2 years I had braces. Smile Studio gave me my confidence back and were always considerate of my time and budget. They offered payment plans for my braces, and worked with my insurance to avoid any financial burden. The ladies at the front desk are always warm and welcoming and the office is beautiful! I highly highly recommend Smile Studio, you will not find a group of professionals who care about you and your smile more.

I wish there was a superstar rating so I could more accurately express just how amazing Dr Rivera…read moreand her entire staff are - 5 stars is barely enough to scratch the surface. Let me put this review into context a bit - I have been to 6 different dentists and Mountain View Dental is my 7th and not all of those were horrible. In fact some were great. But not one was absolutely exceptional the way this office is. I have extremely sensitive teeth and gum recession which causes pain even when I am brushing my teeth or breathing in cold air, causing the need for a lot more patience and precision for the folks at a dental office working on my teeth. Most dentists are more concerned about patient throughput than actually taking care to not cause unnecessary pain with the extra time it takes. But not here - Dr Rivera and her staff are so gentle and comforting I almost feel like I am going to a spa. I have never felt more well cared for then at this office. They provide soft, cozy blankets, tell light hearted stories to keep my mind off the procedure, and put on good TV shows even though I am too nervous (read - uncontrollably crying from anxiety and nerves) to open my eyes to watch them. They don't shame me for this as other dentists have done - they just make it as quick and easy as possible to take good care of my teeth. If you are looking for a new dentist, a second opinion, or simply want to experience the way going to the dentist should be, I cant recommend this office enough.
