    Inside waiting room us beautiful.

    The staff is warm & welcoming. I love the service here. The ladies make you feel like a long time friend. They let you know up front what's covered by your insurance and they're willing to work with you if your insurance doesn't cover something. The office is beautiful inside and the bathroom is really nice & clean. They provide great service and make sure their patients are comfortable. I have a lot of old cavities and my gums are sensitive. They made sure I didn't feel any pain during my cleanings and root canals. Even my 4 year daughter likes going here because of the warm friendly environment. And I love the fact that they text patients when they can't reach you by phone.

    I had to take pictures of the forms Oasis Dental didnt give me

    *** DO NOT COME HERE UNLESS YOU WANT TO BE ROBBED*** I have been forced to place a lawsuit against Oasis Dental due to lack of communication, overcharge, false information, pain and suffering. *Beware* any business that insists that you robo-sign your documents and will not give you copies of their agreement is shady. This business does not return phone calls, and will lie to you about your condition and overcharge your insurance for services that you did not request. I was in a car accident May 2017, despite the airbag being deployed, my head hit the windshield, broke the glass of a Mercedes-Benz S500 that was totaled. I was taken away via Ambulance ended up with a concussion, fractured arm, minor scrapes and 3 broken teeth. Pretty scary. I have 10 ultra white Lumineers, they were approx $1600 each complimented by all white fillings. The teeth that were broken were a bridge near the Lumineers so I wanted to be certain that an authorized Lumineer professional did the repairs. Did not want to damage my investment. I went online to the Lumineer Website, found Oasis Dental, had my Husband's top tier 30 year LAPD Dental insurance verified, told Oasis Dental my issue, they claimed to be Lumineer Specialists and that they understood my issue, I agreed to be prepped. I paid in cash an upcharge to numb the painful shots and endured the discomfort of dentistry. After I sat up I was told that I had been given *two fillings that were ??desperately necessary?? and that I needed to call back later to get verification for the bridge repair!!! Dafuq ***They used ALL OF MY INSURANCE FOR FILLINGS I DIDN'T NEED and had me leave their offices in pain with BROKEN TEETH!!!!*** I have never felt so violated. Why would they do this? I asked when I was going to get my BROKEN teeth repaired and Emma at Oasis told me that I would have to wait until my insurance company reloaded my insurance for 2018!!! WHY? I have money, credit cards TODAY, yet Oasis Dental offered no other suggestions for form of payment. The next day I went to Dr. Jefferson of Sierra Lakes Dental, had my bridge repaired while I watched Sixteen Candles in their modern offices, they took photos and documented the damage on my behalf, gave me a discount and expedited my bridge. I now bring my twin girls there. I reported Oasis Dental to our coverage Delta Dental who informed us in writing that Oasis Dental claimed that they had examined me and that I never had any broken teeth when I came to them. Delta Dental directed me to the California Dental Board and BBB... So I am suing. I ended up having to pay out of pocket because Oasis Dental robbed me, tried to hurt and inconvenience me. Why even suggest that I walk around with broken teeth and a pocket full of money? If they couldn't repair my damage I would have thanked them graciously for their time and moved on. I have filed a lawsuit in Small Claims Court to be compensated for the money I am out because Oasis Dental ripped me off. I am a reasonable person and this could have been worked out easily. I will pursue this until I am satisfied. Not asking for more, just justice. BEWARE*** STAY AWAY**DO NOT COME HERE* unless you don't care what happens to you and you don't mind being treated like a cash register.

    Before and after! 4 baby root canals and reconstruction! Dr. Johnson saved her baby teeth!

The staff did not seem concerned about the risk to my child. They also did not seem educated in preventing allergic reactions for future patients. The clinic was clean and the staff were polite albeit uneducated in food allergies. Those with a tree nut allergy be warned.

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.

    review okay here we go …read more.. I would strongly discourage anyone from coming to this dental office. The quality of the work has been unacceptable. They placed a temporary crown that fell out after only two weeks. I have had temporary crowns before and have never experienced anything like this. When I called for an emergency appointment to have it fixed, they told me they had no availability and suggested I go to CVS to buy temporary tooth repair putty and fix it myself until their next available appointment. That is not the level of care I expect from a dental office. The billing issues have been even worse. After spending over a month going back and forth between the office and my insurance company, I discovered they had charged me more than $1,000 out of pocket for work my insurance had already paid for. On top of that, they billed me for two premium crowns that I never approved or received. I actually received standard porcelain crowns. Their explanation was that these were all "coding mistakes." To make matters worse, they acknowledged that they owe me a refund of over $800, but I was told I have to wait seven days because the person who processes refunds, Kristie, is on vacation. Between the poor dental work, lack of emergency care, repeated billing errors, and the inconvenience of waiting for money that should never have been charged in the first place, this has been an incredibly frustrating experience. I would recommend looking elsewhere if you want quality dental care and accurate billing.

But really do we really know? Unfortunately my wife has had a ton of work done on her teeth throughout the years. We've seen dentists who recommended doing a full mouth reconstruction $60k. She's had multiple root canals and crowns. We went to our normal dentist who said she needs a new crown because a cavity is forming. But we weren't sure. We heard about Kaio Dental from another dentist friend and drove the hour drive from OC to see him. Let's just say we found our new dentist and are willing to drive that hour every 6 months. Dr. Tram is amazing. He taught at Western so he's knowledgeable and skilled. He understands its a changing field and one way is not the correct way. He also knows that explanation to the patient is key. He actually explained to use and showed us with a CT scan why she should hold off on the crown. There was a possible infection in the root so he recommended the imaging being read by an endodontist because if he replaced the crown and introduced bacteria into the area, it may cause even more pain. Something we had no idea on. He has amazing ethics. Isn't in it for the money. Just wants to be a good dentist. He doesn't do same day crowns anymore as he said it's too rushed and he wants focus on the quality since he does it himself. Great team, great office, clean, good parking.
