Based on the reviews, I was expecting and looking forward to a 5-star experience. Unfortunately,…read morethat was not my experience, and I felt I was given 1-star treatment. The female dental assistant was not welcoming or friendly. When I mentioned that I wanted to skip the CBCT scan due to financial reasons, as the cost can be hundreds of dollars depending on insurance, she continued to push the scan 4-5 times despite my clearly stating that I did not want it. I found this extremely uncomfortable and felt that my decision was not being respected. When it came time for the X-rays, the lead apron was tossed onto me rather than being placed on me with care. I have pectus excavatum, which made this particularly uncomfortable and, in my opinion, was not handled professionally. My experience with Dr. Omid Dianat was also concerning. I was placed in a Trendelenburg position, with my head lower than my feet. I have cystic fibrosis and related sinus issues, which make me particularly prone to dizziness and migraine spikes. I had disclosed my medical history and symptoms in the forms I completed prior to the appointment. Being placed in that position exacerbated my symptoms and left me feeling extremely ill afterward. I understand that certain procedures and positioning may be necessary, but I believe my medical history should have been reviewed and taken into consideration before positioning me this way. At the very least, I would have appreciated being informed beforehand so we could discuss whether there was a more appropriate position for me. Additionally, when the electric pulp tester (EPT) was used on an already extremely sensitive tooth, I would have appreciated even a brief warning that the test could cause significant pain. A simple 10-second explanation would have made the experience much less distressing. Overall, I left feeling genuinely disappointed because I had high expectations after reading so many positive reviews. I was hoping to feel heard, respected, and cared for throughout my appointment, particularly after taking the time to provide detailed information about my medical history and concerns beforehand. Instead, I left feeling that my decisions, comfort, and individual needs were not given the level of consideration I expected. I'm sharing this feedback because I believe these concerns could have been addressed with better communication, more attentiveness, and a little more compassion. I hope the office takes this experience seriously and considers how these interactions can be improved so future patients feel more comfortable, respected, and cared for.

I can't say enough great things about this office. I was referred by my dentist for a possible root…read morecanal and to say I was in pain was an understatement. I called on Thursday afternoon. The sweet girl at the front desk literally got me in the next morning. A few hours later I had a root canal. Dr. Lin is very kind and did a great job with this terrified patient. Everyone at this office is awesome. I went from excruciating pain before my root canal to pretty much no pain after. Fabulous office.

UPDATE: Dr. Lin and I spoke on the phone Feb 3, 2026 and he…read morelocated my medical record. We agreed we will discuss a resolution at a future date after we exchange additional documentation with each other. I will update this post when appropriate based on new information. ORIGINAL REIVEW: I got my root canal here before my general dentist could place the crown. After the root canal I went back to the general dentist and upon taking X-rays told me the root canal was done improperly and was incomplete. I had to back to Dr. Lin for a second root canal on the same tooth. Upon going back the GP he said it's a little better but he's still not completely satisfied but would "probably be ok". Facing the reality of having to do a third root canal on the same tooth for "probably" not necessary, I did the crown after the 2nd root canal and hoped for the best. Flash forward about six years later and the same tooth got an abscess bleeding out to the gum. Ended up losing the tooth and had to get an implant suffering through more dental procedures and will end up costing almost $9,000 out of my own pocket for all the work to be done diagnosing and treating the problem with three different specialties and doctors. If the tooth couldn't be saved by Dr. Lin he had a duty to tell me that and then I could have gone to a different doctor or had the tooth pulled. Obviously I couldn't go back to Dr. Lin and this practice because he had already proven to me he is incompetent and can't be trusted. I would advise you to avoid this practice based on incompetence, failure at duty of care and the dangerously poor skill of the doctor. I'm filing the appropriate complaints with the licensing and insurance company. If it were up to me, this doctor would have his license revoked.

I have extreme sensitivity in a tooth with a 10-year-old pulp cap. Last May, I bit into an RX date…read morebar (I've had these many times) and felt sharp pain in tooth #4. For six months I dealt with sensitivity, mainly triggered by hot and cold. I could eat and chew just fine as long as I started chewing on my left side first. Last May, I spoke with my dentist, had X-rays taken, and he told me I'd eventually need a root canal. He didn't give me any other solutions, so I just waited to see if things would get worse. Six months later, I scheduled an appointment with Dr. Gharib's office because the sensitivity was getting to me (even though it was on and off), and I started feeling pain up my cheek. I was worried about potentially having an infection or, even worse, an abscess. Christine at the front desk was so kind and accommodating. It was easy to schedule an appointment. She told me that Dr. Gharib is very conservative and only recommends procedures when absolutely necessary. I figured that was just something she said to everyone. At my appointment, I had X-rays done and reviewed them with Dr. Gharib. He was very kind, soft-spoken, and answered my many (many) questions while listening intently to my concerns. I did not feel rushed at all--I felt like I was actually being heard. After his examination, he didn't see any infection on the X-ray, but it did show a slight fracture in the pulp cap filling, which could be the cause of the heightened sensitivity. He didn't pressure me to do a cone beam scan or even suggest it; I personally requested it because I wanted to be absolutely sure there wasn't an infection at the root, since that would make a root canal necessary. The cone beam scan confirmed I had no infection whatsoever--thank goodness. He sat with me for a long while discussing what I could do to help the sensitivity and the slight fracture. He said it might be as simple as replacing the filling with an inlay or onlay, but since my pulp cap is very close to the nerve, that carries the risk of needing a root canal if it fails. He suggested trying Sensodyne for a few weeks and then having my dentist check whether an inlay or onlay, to replace the filling, is an option. There's a chance that might fix the problem. After my appointment, I felt so much more at ease. I was relieved that I didn't have an infection and grateful that I actually had options before committing to a root canal. Dr. Gharib even wrote me a long email afterward, reiterating everything we talked about. That, right there, is a dentist who truly cares. If and when I ever need a root canal, I'll be going to Dr. Gharib. He is professional, honest, thorough, and welcomes ALL questions. All the positive reviews you've read are true. Not every dentist cares like this!

His expertise professionalism, and honesty immediately stood out.It's clear from both his credentials and patient reviews that he genuinely cares about doing what's best for his patients-not just making a profit. After my previous experiences, I felt genuinely relieved and confident in his care. I highly recommend Dr. Gharib to anyone who's seeking an honest and skilled endodontist.

The team that provided dental care to me was kind and welcoming. They made me feel comfortable from the moment I arrived. My hygienist was Bruce. He was personable and easy to have a conversation with. He and the dentist (can't remember her name, but she was very kind) were thoughtful, patient, and explained everything thoroughly. They made sure all of my concerns were addressed. What really stood out was the personalized care. They looked at my specific needs and made recommendations that were affordable and made sense. I appreciated that they focused on what would work best for me instead of giving generic recommendations. Additionally, I need to have a crown due to a fractured tooth. I already knew this might come up because a previous dental office had mentioned it. However, that dental office wanted 2 1/2 times the amount out of pocket than Oceanic Dental. They provided a print out of the work to be done, how much would be billed to my insurance and how much was my responsibility. Best of all, they left it to me to make the decision on when and didn't try to persuade me. It was a completely pressure free experience. You can tell the staff values their patients and wants every visit to be a positive experience. Their attention to detail and genuine concern for patient care made a lasting impression. The only con here is that the parking can be difficult during very busy times. However, I highly recommend Oceanic Dental to anyone looking for a dental office where you'll feel well cared for and treated with kindness.
